A freely falling observer  is equivalent to an inertial observer who experiences no acceleration according to the equivalence principle (option B)

The equivalence principle establishes that the gravitational force encountered in a localized region is indistinguishable from the pseudo-force perceived by an observer situated within a non-inertial (accelerated) frame of reference.

Consequently, an observer in free fall within a gravitational field undergoes no discernible acceleration, mirroring the experience of an inertial observer.

Answer:

(a) The total weight of the climber is equal to her mass multiplied by the acceleration due to gravity. Therefore, W = mg = 62 kg x 10 m/s^2 = 620 N.

(b) The two conditions needed for equilibrium are that the net force acting on the climber is zero and the net torque acting on the climber is zero.

(c)(i) The moment about her feet due to her weight is equal to the weight of the climber multiplied by the distance between her feet and the cliff. Therefore, M = W x d = 620 N x 0.9 m = 558 Nm.

(ii) To determine the tension in the rope, we need to resolve the forces acting on the climber in the horizontal and vertical directions. In the horizontal direction, the tension in the rope is balanced by the force of friction between the climber's feet and the cliff. Therefore, T = F.

In the vertical direction, the climber's weight is balanced by the normal force of the cliff and the tension in the rope. Therefore, N + Tcos(60) = W.

Since the climber is in equilibrium, the net torque acting on her must be zero. Therefore, the torque due to the tension in the rope must be equal and opposite to the torque due to the climber's weight. Therefore, Tsin(60) x 1.2 = M.

Substituting the values we have, we get:

N + Tcos(60) = W

Tsin(60) x 1.2 = M

Solving for T, we get:

N = W - Tcos(60) = 620 N - T(0.5)

Substituting this into the second equation, we get:

Tsin(60) x 1.2 = M

Tsin(60) = M / 1.2 = 558 Nm / 1.2 m = 465 N

Substituting this value of T into the first equation, we get:

N = 620 N - T(0.5) = 620 N - 465 N(0.5) = 388 N

Therefore, the tension in the rope is 465 N and the normal force of the cliff on the climber is 388N

Answer: 0.85 N

Explanation: We can solve this problem using the principles of buoyancy and Newton's laws.

First, we need to find the buoyant force acting on the metallic alloy block. The buoyant force is equal to the weight of the water displaced by the block, which can be calculated using the block's volume and the density of water:

V = m_block / ρ_block = 3.4 kg / 3700 kg/m³ = 0.0009189 m³

F_buoyant = ρ_water x g x V = 1000 kg/m³ x 9.8 m/s² x 0.0009189 m³ = 8.96 N

So the buoyant force acting on the metallic alloy block is 8.96 N.

Next, we can calculate the tension force in the spring scale attached to the block. Since the block is in static equilibrium, the tension force must be equal in magnitude and opposite in direction to the weight of the block plus the buoyant force:

Tension force = weight of block + buoyant force

Tension force = m_block x g + F_buoyant

Tension force = 3.4 kg x 9.8 m/s² + 8.96 N = 42.04 N

So the hanging scale reads 42.04 N.

Finally, we can find the reading of the lower scale. The lower scale measures the weight of the beaker and the water in it, minus the buoyant force acting on the beaker. The weight of the beaker and the water is:

weight of beaker + weight of water = m_beaker x g + m_water x g

weight of beaker + weight of water = 1.3 kg x 9.8 m/s² + 2.5 kg x 9.8 m/s² = 35.35 N

The buoyant force acting on the beaker can be calculated using the volume of water displaced by the beaker:

V = m_water / ρ_water = 2.5 kg / 1000 kg/m³ = 0.0025 m³

F_buoyant = ρ_water x g x V = 1000 kg/m³ x 9.8 m/s² x 0.0025 m³ = 24.5 N

So the reading of the lower scale is:

Reading of lower scale = weight of beaker + weight of water - buoyant force

Reading of lower scale = 35.35 N - 24.5 N = 10.85 N

Therefore, the lower scale reads 10.85 N.

If the electron gun distance and electron deflection distance both double, while the electric fields stay the same, then the angle of deflection would also double.

This is because the electric field strength is directly proportional to the angle of deflection, and since the electric field strength is staying the same, the angle of deflection increases proportionally with the increase in distance.

The equation to determine the angle of deflection is as follows: θ = Vd/E, where θ is the angle of deflection, V is the velocity of the electron, d is the distance between the electron gun and deflection plate, and E is the strength of the electric field.

When the distance between the two plates doubles, the angle of deflection will also double. Therefore, if the electron gun and electron deflection plate are both doubled in distance, the angle of deflection would be double the original angle.

1.3 m/s is the average speed of runner. Option D is the correct answer.

The total distance covered by the runner in one lap is equal to the distance around the two semicircles plus the distance along the two parallel lines. The distance around one semicircle is πr = π(49 m) and since there are two semicircles, the total distance around the semicircles is 2π(49 m). The distance along each parallel line is 96 m, and since there are two parallel lines, the total distance along the parallel lines is 2(96 m). Therefore, the total distance covered by the runner in one lap is:

Total distance = 2π(49 m) + 2(96 m) = 2π(49 m + 48 m) = 2π(97 m)

The time taken by the runner to complete one lap is given as 100 seconds. Therefore, her average speed is:

Average speed = Total distance / Time taken = [2π(97 m)] / (100 s) = 1.93 m/s

Rounding to two significant figures, the average speed of the runner is 1.9 m/s, which corresponds to option (D) 1.3 m/s.

Sound travels at a known speed, the time interval between the flash and the thunderclap can be used to calculate the approximate distance to the lightning strike.Light travels at a speed of approximately 299,792 kilometers per second in a vacuum, while sound travels at a much slower speed of around 343 meters per second in dry air at 20 degrees Celsius.

The scientist observed the lightning flash several seconds before hearing the sound of the thunderclap because light travels much faster than sound. Light travels at a speed of approximately 299,792 kilometers per second in a vacuum, while sound travels at a much slower speed of around 343 meters per second in dry air at 20 degrees Celsius.Given that the scientist was several kilometers away from the lightning flash, the light from the flash reached the scientist's location almost instantaneously. In contrast, the sound waves generated by the thunderclap took time to travel through the air over the distance between the scientist and the lightning. Consequently, it took several seconds for the sound to reach the scientist's ears.The time difference between seeing the lightning flash and hearing the thunder allows us to estimate the distance of the lightning strike.

The strong nuclear force overcomes the repulsive electric force of protons in the atomic nucleus because it is a much stronger force. It is able to act over very short distances and is mediated by particles that are much heavier than electrons and photons.

The repulsive electric force of protons in the atomic nucleus does not cause the protons to fly apart because of the strong nuclear force. The strong nuclear force is an attractive force between nucleons that overcomes the repulsion between protons due to the electromagnetic force. This force is responsible for holding the nucleus of an atom together.

We will explain the physics behind why the strong nuclear force overcomes the repulsive electric force. The protons in the nucleus are positively charged and would normally repel each other due to the electrostatic force. The reason why they do not is because they are held together by a stronger force, the strong nuclear force. This force acts between nucleons, which are particles found in the nucleus of an atom. The strong nuclear force is a short-range force that acts over distances of less than a femtometer. It is much stronger than the electrostatic force, which is why it is able to hold the nucleus together. The reason for this is that the strong nuclear force is mediated by particles called mesons, which are much heavier than electrons and photons. The strong force is able to overcome the repulsion between protons because it is much stronger than the electromagnetic force, which is what causes the repulsion in the first place.

If bulb B  is replaced with a short circuit, it will effectively bypass the circuit that includes bulb A. As a result, the current in the circuit will increase, which may cause the bulb A to become brighter.

A circuit is a closed path or loop through which electrical current can flow. It is made up of various components that work together to allow the flow of electricity. The basic components of a circuit include a power source, such as a battery or generator, wires or conductors that carry the current, and various other components such as switches, resistors, capacitors, and diodes, which help to control and modify the flow of electricity.

When a circuit is closed, the electrical current flows from the power source through the components and back to the power source. This flow of electricity is usually measured in amperes (amps) and is controlled by the voltage of the power source and the resistance of the components in the circuit.

Circuits can be either series circuits, where the components are arranged one after the other in a single loop, or parallel circuits, where the components are arranged in multiple branches, allowing the current to flow through each component independently. Circuits are used in a wide range of electrical and electronic devices, from simple household appliances to complex computer systems and telecommunications networks.

If bulb B is replaced with a short circuit, it will effectively bypass the circuit that includes bulb A. As a result, the current in the circuit will increase, which may cause the bulb A to become brighter. However, it's also possible that the increased current could cause bulb A to burn out or even damage the circuit itself. In general, it's not recommended to create a short circuit intentionally as it can be dangerous and potentially cause damage to the electrical system.

The electric potential energy of the system is approximately 38.64 Joules.

To calculate the electric potential energy (U) of the system, we can use the formula for the potential energy of a system of point charges:

U = k * (q₁ * q₂ / r₁₂ + q₁ * q₃ / r₁₃ + q₂ * q₃ / r₂₃)

Where:

U is the electric potential energy

k is the electrostatic constant (8.99 × \(10^9\) N m²/C²)

q₁, q₂, q₃ are the charges

r₁₂, r₁₃, r₂₃ are the distances between the charges

Given:

Charge of each point charge (q₁ = q₂ = q₃) = 1.00 μC = 1.00 × \(10^-^6\) C

Side length of the equilateral triangle (a) = 0.700 m

The distances between the charges can be calculated using the properties of an equilateral triangle:

r₁₂ = r₁₃ = r₂₃ = a

Now we can substitute the given values into the formula for electric potential energy:

U = (8.99 × \(10^9\) N m²/C²) * [(1.00 × \(10^-^6\) C)² / (0.700 m) + (1.00 × \(10^-^6\) C)² / (0.700 m) + (1.00 × \(10^-^6\) C)² / (0.700 m)]

Simplifying the expression:

U = (8.99 × \(10^9\) N m²/C²) * [(1.00 ×\(10^-^6\) C)² * 3 / (0.700 m)]

U = (8.99 × \(10^9\) N m²/C²) * [(1.00 ×\(10^-^6\) C)² * 3 / (0.700 m)]

U ≈ 38.64 J

To calculate the object's terminal velocity, we need to consider the forces acting on it. The main forces at play are gravity and air resistance. The force due to gravity can be calculated using Newton's second law:

F_gravity = m * g,

where m is the mass of the object (5 kg) and g is the acceleration due to gravity (approximately 9.8 m/s²).

The force of air resistance can be expressed as:

F_air = -k * v,

Where k is a constant related to the shape and properties of the object, and v is the velocity of the object. The negative sign indicates that the force of air resistance opposes the motion of the object.

At terminal velocity, the forces due to gravity and air resistance are balanced, resulting in no net force acting on the object. Therefore, we can equate these two forces:

m * g = -k * v.

Solving for v, we get:

v = -(m * g) / k.

Now, we need to determine the value of k using the provided information about air resistance. The dampening from air resistance is given as y = 3 kg/sec. The force of air resistance is proportional to the velocity, so we can write:

F_air = -y * v.

Comparing this equation with F_air = -k * v, we can see that k = y.

Plugging in the values, we have:

v = -(m * g) / k = -(5 kg * 9.8 m/s²) / 3 kg/sec ≈ -16.33 m/s.

The negative sign indicates that the terminal velocity is in the opposite direction of motion (upward in this case). Therefore, the object's terminal velocity is approximately 16.33 m/s.

When a compound's spectrum has more than one λmax (wavelength of maximum absorption), it indicates that the compound has multiple chromophores or functional groups that can absorb light at different wavelengths.

The presence of multiple λmax in a compound's spectrum suggests that there are different chromophores or functional groups within the compound that are responsible for absorbing light at distinct wavelengths. Chromophores are groups of atoms within a molecule that exhibit electronic transitions, resulting in the absorption of light.

Each chromophore or functional group has its own characteristic absorption spectrum, and the position of its λmax corresponds to the specific wavelengths at which it absorbs light most strongly. Therefore, when a compound possesses multiple chromophores or functional groups, each contributing to the absorption of light, the spectrum exhibits multiple λmax.

The presence of multiple λmax can provide valuable information about the structure and composition of a compound. By analyzing the positions and intensities of the different absorption peaks, researchers can gain insights into the specific chromophores or functional groups present and their electronic transitions.

To determine the coefficient of kinetic friction between the box and the floor, we can use the following formula:
friction force = coefficient of friction * normal force

In this case, since the box comes to rest, the friction force acting on the box is equal to the force applied to the box in the opposite direction. The normal force is the force exerted by the floor on the box, which is equal to the weight of the box.The formula for the force applied is:
force applied = mass * acceleration
Since the box comes to rest, the friction force is zero. Therefore, the force applied is also zero. Now, we can rewrite the equation for the friction force as:
0 = coefficient of friction * weight
The weight of the box is equal to the mass of the box multiplied by the acceleration due to gravity (9.8 m/s^2). Now, we can determine the coefficient of kinetic friction by rearranging the equation:
coefficient of friction = 0 / weight
coefficient of friction = 0 / (mass * acceleration due to gravity)
Since the box has mass, we cannot divide by zero. Therefore, the coefficient of kinetic friction between the box and the floor is zero. Please note that a coefficient of kinetic friction of zero implies that there is no friction between the box and the floor, which may not be realistic in most scenarios.

The electrostatic force between the negatively charged rod and the metal can will increase when additional negative charges are added to the rod, while the gravitational force between them will remain the same.

This is because the electrostatic force between the rod and the can is proportional to the charge on the rod and the distance between them, according to Coulomb's law. Adding additional negative charges to the rod increases its total charge, which in turn increases the electrostatic force between the rod and the can.

On the other hand, the gravitational force between the rod and the can is determined by their masses and the distance between them, according to the law of gravitation. Since neither the mass nor the distance between the rod and can changes in this experiment, the gravitational force remains the same.
