The charge on the second sphere is -9.6×10⁻⁶ C.

The force of attraction or repulsion between two charged things is directly proportional to the product of their charges and inversely proportional to the square of their distance, according to Coulomb's law.

Given, Q1 = +2.3 x 10⁻⁶ C

distance, r = 2m

attraction force, Fa = 0.05N

now by using Coulombs law,

Fa = k×Q1×Q2/r

0.05 =  9×10⁹×2.3 x 10⁻⁶ × Q2 /2

Q2 = 2×0.05/ 9×10⁹×2.3 x 10⁻⁶

Q2 = 9.6×10⁻⁶ C.

Since it is an attractive force therefore charges will be opposite,

The charge on the second sphere is -9.6×10⁻⁶ C.

Answer:

a. 10.2 N b. 1.73 c. 58.8 N d. 10.2 N

Explanation:

a. The force that will make the block slide down the plane

This is the component of the block's weight along the plane F = mgsinθ where m = mass of block = 1.2 kg, g = 9.8 m/s² and θ = angle of incline = 60°.

So, F = mgsinθ = 1.2 kg × 9.8  m/s² × sin60°.= 10.18 N ≅ 10.2 N

b. The coefficient of friction

The coefficient of friction, μ = tanθ = tan60° = 1.73

c. The normal reaction.

This is equal to the vertical component of the block's weight. So, F = mgcosθ. Substituting the values for the variables from above, we have

F = mgcosθ = 1.2 kg × 9.8  m/s² × cos60°.= 58.8 N

d. The frictional force

Since the block does not slide, there is no net force on it. If f is the frictional force, then

F - f = ma. Since a = acceleration = 0,

F - f = 0

f = F = mgsinθ = 1.2 kg × 9.8  m/s² × sin60°.= 10.18 N ≅ 10.2 N

The possible genotypes of the offspring are: TT, Tt, and tt.

The possible phenotypes of the offspring are: tall and short.

The percentage chance of being homozygous can be calculated using a Punnett square. When the heterozygous parents are crossed, the possible genotypes of the offspring are:

| T | t

--|---|---

T | TT| Tt

t | Tt| tt

From the Punnett square, we can see that there is a 25% chance of the offspring being homozygous (TT or tt). This is because there are four possible outcomes and two of them result in a homozygous genotype (TT and tt).

Answer:

E(nergy) = V * Q        where V(oltage) = work/charge

E = 50 J/C * 1.6E-19 C = 8.0E-18 Joules

The proton gains approximately 8.01 x \(10^-18\) joules of energy as it accelerates through the 50-volt electric potential difference.

To calculate the energy gained by a proton as it accelerates through an electric potential difference, we can use the formula:

Energy (in joules) = Charge of the particle (in coulombs) × Electric potential difference (in volts)

The charge of a proton is approximately 1.602 x \(10^-19\) coulombs.

Given that the electric potential difference is 50 volts, we can now calculate the energy gained by the proton:

Energy = (1.602 x \(10^-19\) C) × (50 V)

Energy ≈ 8.01 x \(10^-18\) joules

Hence, the proton gains approximately 8.01 x \(10^-18\) joules of energy as it accelerates through the 50-volt electric potential difference.

The non-conservative work done on the stone (Wnc) is equal to the change in mechanical energy is -4.8 J.

To find the non-conservative work (Wnc) done on the stone, we need to consider the change in mechanical energy.

The mechanical energy of an object consists of its potential energy (PE) and kinetic energy (KE):

Mechanical Energy (E) = Potential Energy (PE) + Kinetic Energy (KE)

At the initial position, when the stone is dropped, all its energy is in the form of potential energy since it is not yet in motion. The potential energy can be calculated using the formula:

PE = m * g * h

where:

m = mass of the stone = 0.05 kg

g = acceleration due to gravity = 9.8 m/s^2

h = height = 10 m

PE = 0.05 kg * 9.8 m/s^2 * 10 m

PE = 4.9 J

At the final position, just before the stone strikes the ground, its energy is in the form of kinetic energy. The kinetic energy can be calculated using the formula:

KE = (1/2) * m * v^2

where:

m = mass of the stone = 0.05 kg

v = velocity = 2 m/s

KE = (1/2) * 0.05 kg * (2 m/s)^2

KE = 0.1 J

The change in mechanical energy (ΔE) is given by:

ΔE = KE - PE

ΔE = 0.1 J - 4.9 J

ΔE = -4.8 J

The negative sign indicates that there was a loss of mechanical energy due to non-conservative forces such as air resistance or friction.

Therefore, the non-conservative work done on the stone (Wnc) is equal to the change in mechanical energy. So, the non-conservative work done on the stone is -4.8 Joules.

When a cable with 19.01 N of tension pulls straight up on a 1.79 kg block that is initially at rest, the block's speed after being lifted 1.62 m is 3.01 m/s.

What is tension?

Tension is the force experienced by an object that is pulled or stretched.

When a cable with 19.01 N of tension pulls straight up on a 1.79 kg block that is initially at rest, the tension in the cable balances the weight of the block, which is 1.79 kg multiplied by the acceleration due to gravity of 9.8 m/s² or 17.542 N.

So, tension = 19.01 N (since the cable tension is the only force acting on the block).

Therefore, using the work-energy theorem,

W = ∆K,

where W is the work done on the block,

∆K is the change in the block's kinetic energy,

K = 1/2 m(v²).

Since the block begins at rest, K = 0 Joules when it starts moving upward, and it has some final velocity when it reaches 1.62 m.

So, W = 1/2 m(v²).

From the given data, the work done on the block is F∆y, where F is the force on the block, and ∆y is the distance the block has been lifted up to reach 1.62 meters of height.

So,∆K = F∆y∆K

= (19.01 N)(1.62 m)∆K

= 30.8182 J

The block's kinetic energy after reaching 1.62 meters of height is the same as the work done on it since no other external forces acted on it.

Therefore,

1/2 m(v²)

= 30.8182 J1/2 (1.79 kg)(v²)

= 30.8182 Jv²

= 34.31 v = 3.01 m/s

Therefore, the block's speed after being lifted 1.62 meters is 3.01 m/s.

The speedometer of a car measures instantaneous speed. It tells you the speed of the car at any given moment in time.

The speedometer of a car measures instantaneous speed. This means it gives the reading of the speed at any given moment in time.

Main part: The speedometer of a car measures instantaneous speed. It tells you how fast you are driving at that particular moment. The speedometer gives you a direct reading of how fast your vehicle is traveling. It measures the vehicle's speed at any given moment in time, rather than calculating the average speed of the entire journey.

A speedometer is attached to a vehicle's wheels to measure its speed. As the wheels turn, the speedometer calculates the speed at which they are turning. Inside the speedometer, there is a component called a speedometer cable. This component is connected to the back of the speedometer's drive mechanism. The other end of the cable is connected to a gear that is inside the transmission or the transfer case. When the vehicle is moving, the driveshaft turns the gears in the transmission or transfer case. The gear connected to the speedometer cable also turns, causing the cable to rotate. The rotation of the cable creates a magnetic field that drives the speedometer's magnetometer, which is connected to the speedometer pointer. This causes the pointer to move along the dial and show the speed of the vehicle on the speedometer.

Conclusion: In conclusion, the speedometer of a car measures instantaneous speed. It tells you the speed of the car at any given moment in time.

Answer:

Average Velocity = 3.65 m/s

Explanation:

Average Velocity  \(=\frac{Total Displacement}{Total Time}\) \(=\frac{22.1-3.85}{5}=\frac{18.25}{5}=3.65\)

The average velocity of a ball that rolls from x=3.85m to x=22.1m in 5 seconds is -3.65 m/s.

Given the following values:

Initial position, x = 3.85 m

Final position, x'= 22.1 m

Initial time, t = 0 seconds

Final time, t'= 5 seconds

The average velocity can be computed from the ratio of change in displacement and time.

The average velocity is given as:

v = (x'-x)/(t'-t)

v = (22.1-3.85)/(5-0)

v = -3.65 m/s

Hence, the average velocity of a ball that rolls from x=3.85m to x=22.1m in 5 seconds is -3.65 m/s.

Conservation of momentum describes what happens in a collision. When two objects collide, the total momentum of the objects before the collision equals the total momentum of the objects after the collision.

What is Collision?

A collision occurs when two or more objects come into contact with each other, and as a result, they exchange energy, momentum, and/or other physical quantities. Collisions can be either elastic or inelastic, depending on whether or not there is a loss of kinetic energy during the interaction.

Newtons laws of motion can be used to explain events in the natural world, such as how a pencil falls to the floor and how planets revolve around the sun. In the absence of air, all objects fall at the same rate, because the force of earth’s gravity causes objects to accelerate by 9.8 m/s, downwards, towards the ground. Air resistance can eventually counteract the acceleration from gravity. This is why a flat piece of paper falls slowly, but when the same paper is crumpled, it falls quickly. When the upward force of air resistance on an object equals the downward force of gravity on the object, it’s velocity stops increasing. This is called the object’s terminal velocity. Satellites orbit Earth because of gravity. They travel very fast, but with each meter forward that they travel, they decelerate just a tiny bit due to Earth’s gravity. Astronauts in Earth’s orbit experience weightlessness because they are in freefall. Without gravity, satellites would continue in a straight line away from Earth. Newton’s laws also describe what happens in collisions. For example, in a moving car, a passenger is also in motion. When the car comes to a sudden stop, the passenger continues in motion. To protect the passenger from striking the inside of the car, seatbelts, airbags, and other safety features decelerate passengers slowly.
