9) A vector describe as a quantity that has both magnitude and direction. 10) We use vectors to describe in physics in physical quantities, including displacement, velocity, acceleration, force, momentum, and torque.

The vector is typically represented by an arrow, with the length of the arrow representing the magnitude of the vector and the direction of the arrow representing the direction of the vector. In addition to the magnitude and direction, vectors also have a starting point and an end point. Vectors can be added together to obtain a resultant vector that represents the sum of the individual vectors. Vectors can also be subtracted, multiplied by a scalar, or divided by a scalar.

For example, displacement is a vector that describes the distance and direction between two points. Velocity is a vector that describes the speed and direction of motion and acceleration is a vector that describes the rate at which velocity changes. Force is a vector that describes the push or pull on an object and momentum is a vector that describes the motion of an object and its resistance to change. Torque is a vector that describes the rotational motion of an object. So therefore vectors are an important tool for physicists because they allow them to describe physical quantities in a way that is both concise and precise.

To find the velocity of the particle, we need to find the derivative of the equation of motion, s = f(t), with respect to time t.

Let's denote the velocity as v(t):
v(t) = f'(t)
Given that the equation of motion is s = f(t), we need to differentiate it with respect to t:
ds/dt = f'(t)
Now, let's substitute the given values. When t = 4, we can evaluate the derivative at that point:
v(4) = f'(4)

To find the speed at t = 4, we need to find the magnitude of the velocity. The speed is always positive, regardless of the direction of motion.

Therefore, we can take the absolute value of the velocity:
speed = |v(4)|

Please note that without the specific equation of motion, it is not possible to provide the exact values for velocity and speed at t = 4.

TRUMP KILLED 223,000 PEOPLE AND HE STILL DOES NOT CARE! HE SAYS WE ARE ROUNDING THE CORNER. HE CAN NOT EVEN HAND OUT STIMULUS TO DYING BUISNESSES AND AIRLINES!

The rear window of an automobile is defogged by passing warm air over its inner surface. The temperature of the warm air is denoted as t[infinity].

The rear window of an automobile can be cleared of fog by circulating warm air over its inner surface. This process involves directing warm air onto the window to raise its temperature and prevent condensation. The temperature of the warm air used for defogging is represented as t[infinity].

By passing this warm air over the inner surface of the window, heat is transferred from the air to the window, raising its temperature and reducing the temperature difference between the window and the surrounding air.

This helps to eliminate or minimize the formation of condensation on the window, improving visibility for the driver. The warm air effectively acts as a heat source, counteracting the cooling effect that leads to fog formation on the window.

A basketball player running at 4.60 m/s directly towards the basket jumps into the air to dunk the ball while maintaining his horizontal velocity.

When the basketball player jumps into the air, he experiences a parabolic trajectory due to the effects of gravity. However, since he maintains his horizontal velocity, his horizontal motion remains unaffected throughout the jump.

The vertical motion of the player can be analyzed using the equations of motion under constant acceleration. The initial vertical velocity is zero, and the acceleration due to gravity is approximately 9.8 m/s². Using these values, we can calculate various parameters of the player's jump.

For instance, the time it takes for the player to reach the peak of his jump can be found using the equation v = u + at, where v is the final vertical velocity (which is zero at the peak), u is the initial vertical velocity, a is the acceleration due to gravity, and t is the time.

The maximum height reached by the player can be determined using the equation h = ut + 0.5at², where h is the height, u is the initial vertical velocity, a is the acceleration due to gravity, and t is the time.

Since the player maintains his horizontal velocity throughout the jump, his horizontal displacement remains the same, which depends on the initial horizontal velocity and the time of flight.

By solving these equations, we can obtain the specific values for the time of flight, maximum height reached, and horizontal displacement of the player during his jump.

The combination of a wire coil and a core would make the weakest electromagnet 20 coils of insulated wire around a hollow cardboard core. Thus, option B is correct.

Electromagnet is a type of magnet that produces its magnetic field when an electric field is applied across the material. The electromagnet is the temporary magnet as it acquires the magnetic properties when the electric current passes through it. When there is no electric current, its magnetic properties disappear.

Electromagnet consists of a wire wound on the coil and the current passes through the wire. The wire wound on the coil is mostly a ferromagnetic material like iron and the coil is a soft iron core. In an electromagnet, the magnetic field depends on the number of turns of the coil and the current flows through it.

From the given, steel core is wounded with wire it makes a strong electromagnet depending on the number of turns of the coil. The cardboard core is not a ferromagnetic material and hence, a small number of turns over the cardboard forms the weakest electromagnet.

5. All the resistors in this circuit, the 18 Ω resistor included, are in parallel. The voltage drop across each resistor is the same, which is the equivalent to the potential difference of the battery. That is, 36 V [choice K].

6. The ammeter is in series with the branch containing a 12 Ω resistor. Since the voltage drop across this resistor is 36 V, the current in this branch will be I = V/R = (36 V)/(12 Ω) = 3.0 A [choice D].

7. The equivalent resistance of the circuit can be calculated as follows:

1/R = 1/12 + 1/9 + 1/18 = 1/4; thus, R = 4.0 Ω [choice G].

8. Electrical power can be defined as electrical work/time, and electrical work can be given by W = qV. If P = qV/t and q/t = I (charge flowing per unit time is equal to current), then P = VI. From Ohm's law, V = IR, and I = V/R. Substituting V/R for I in the power equation, P = V²/R.

For this circuit, the V = 36 V and R (the equivalent resistance) = 4.0 Ω. So, the power loss in the circuit is P = (36 V)²/(4.0 Ω) = 324 W [choice J].

The thrown football has Potential or stored Energy, PE, by virtue of its position in the air and the ability for it to fall by itself. The thrown football also has Kinetic Energy, KE, given that the ball is in motion and requires an equal and opposite amount of energy to stop it. Both the PE and the KE  are forms of Mechanical Energy, ME and the Mechanical Energy of the football is equal to the sum of its Potential and Kinetic Energy. That is ME = PE + KE

Explanation:

Potential energy, PE, is the energy that is the held or stored energy of a body such that the body is able to do work without the addition of energy from an external source

A thrown football that has an elevation or height above the floor level has the capacity to come back down and bounce on the floor without the presence of assistance at the topmost height of the football. Therefore, the thrown football has potential energy, given to it by the thrower

Kinetic Energy, KE, is the energy possessed by a moving that comes from the motion of the object

Given that the thrown football is in motion, it posses kinetic energy

Therefore, the thrown football possesses both potential energy and kinetic energy which are forms of mechanical energy ME

The combined energy of the football is therefore called the Mechanical Energy ME of the ball which is the sum of the potential and kinetic energies of the football, given as follows;

The Mechanical Energy of the football = The Potential Energy of the football + The Kinetic Energy of the football

∴ ME = PE + KE

Answer:

See explanation below

Explanation:

In this case, you want to know if you put an object between these forces, which direction would go.

To know this, we need to calculate the moment of an object, which is defined as the product of a force and it's distance. In other words:

M = F * d   (1)

And, in order to reach equilibrium the force will exert a direction in clockwise or anticlosewise, and these moments, should be even:

anticlockwise moment = clockwise moment.

The clockwise would be the forces to the right, and anticlock would the only force to the left of the axle.

Clockwise moment = (10 * 0.8) + (25 * 2.6) = 73 Ns

Anticlockwise moment = 34 * 3.5 = 119 Ns.

As we can see, the moment in the anticlockwise is higher than the actual clockwise moment, therefore, we can assume that the object will move anticlockwise, or simply move to the left.

Answer:

0.27475 N

Explanation:

To find the net force acting upon q2, we need to find the force exerted by q1 to q2 and the force exerted by q3 to q2, and to do that we should apply the formula

\(F = |\frac{kq_{1}q_{2} }{r^{2} }|\)

where in k is coulomb's constant (\(8.99*10^9 \frac{Nm^{2}}{C^{2}}\))

q1 and q2 are the charges

and r is the distance between the two charges.

Finding the force exerted to q2 by q1:

\(F = |\frac{(8.99*10^{9} * (-5*10^{-6}) * (2.5*10^{-6})}{(0.500)^{2}}|\)

F = 0.4995 N

q1 would be attracted to q2, so it would go to the right, so it's a positive force

Finding the force exerted to q2 by q3:

\(F =|\frac{(8.99*10^{9})*(-2.5*10^{-6})*(2.5*10^{6})}{0.250^{2}}|\)

F = 0.22475 N

q3 would be attracted to q2, so it would go to the left, so it's a negative force

F = -0.22475N

Add-up the forces: 0.4995 + (-0.22475) = 0.27475 N

The collisions that are considered inelastic are the ball of clay dropped onto the floor (clay sticks to the floor) and the bullet colliding with a block of wood (bullet embedded in the wood).

The collision of a golf club hitting a golf ball and the rubber ball dropped onto the floor are not specified as inelastic in the given options.An inelastic collision is one in which kinetic energy is not conserved, meaning that the total kinetic energy of the system before the collision is different from the total kinetic energy after the collision. In the case of the ball of clay dropped onto the floor, the clay sticks to the floor, resulting in a loss of kinetic energy and deformation of the clay, indicating an inelastic collision.

Similarly, when a bullet collides with a block of wood and gets embedded, there is a loss of kinetic energy and deformation, indicating an inelastic collision. On the other hand, the golf club hitting a golf ball and the rubber ball dropped onto the floor do not provide sufficient information to determine if the collisions are specifically inelastic.

Answer:

the number of loops in the coil and the electric current.

Explanation:

Just took the test and got it correct.

The most likely cause of a change in action potential shape is alterations in ion channel activity, which affect the flow of ions across the cell membrane.

Action potentials are electrical signals generated by excitable cells, such as neurons and muscle cells, to transmit information. The shape of an action potential is determined by the coordinated opening and closing of ion channels, which allow the selective passage of ions across the cell membrane. Any disruption in ion channel activity can lead to changes in the action potential shape.

Several factors can cause alterations in ion channel activity. Mutations in ion channel genes can result in dysfunctional channels that fail to open or close properly. This can lead to prolonged depolarization or repolarization phases, resulting in a change in the action potential shape. Additionally, changes in the concentration of ions, such as potassium or calcium, can impact the activity of ion channels, leading to modifications in the action potential waveform.

External factors, such as drugs or toxins, can also influence ion channel activity and subsequently affect action potential shape. For example, certain medications can block specific types of ion channels, altering the membrane potential and changing the action potential morphology. Similarly, toxins produced by bacteria or other organisms can interfere with ion channel function, leading to abnormal action potentials.

In summary, alterations in ion channel activity caused by genetic mutations, changes in ion concentrations, drugs, or toxins are the most likely causes of changes in action potential shape. These disruptions can affect the flow of ions across the cell membrane and result in modifications to the characteristic waveform of action potentials.
