Inelastic collision and a host of other factors causes the loss of energy.

Kinetic energy of an object is the energy that it possesses due to motion.

It can be defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. When it has gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

In an inelastic collision which is the case of ball X and Y, the kinetic energy of the system is not conserved. The energy that you find lost has been dissipated as other forms of energy. This can be heat, friction, vibrational energy transferred to atoms of the colliding particles, energy lost to deform the atomic structure etc.

In conclusion, the inelastic collision nature of the two balls results in the loss of energy through different forms.

Since the velocity is constant, the change in velocity is 0, which means that the acceleration is also 0. Therefore, the magnitude of the acceleration that the car experiences is 0.

The speed of the car is given as 65 miles per hour (mph). Therefore, the speed of the car is given by:

v = 65 mph

The time taken by the car to travel is given as 30 minutes. Therefore, the time taken is given by:

t = 30 minutes

= (30/60) hours

= 0.5 hours.

The distance traveled by the car can be calculated using the formula :

d = v × td

= (65 × 0.5) miles

= 32.5 miles1 mile is equal to 1608 meters.

Therefore, the distance traveled by the car is:

d = 32.5 miles

= (32.5 × 1608) meters

= 52140 meters

The magnitude of the acceleration that the car experiences can be calculated using the formula: a = Δv/Δt

Here, Δv is the change in velocity and Δt is the time interval. In this case, the velocity is constant.

Therefore, Δv = 0

We know that, v = d/t

Rearranging this formula, we can write t = d/v

Substituting the values of d and v, we get:

t = (52140 meters)/(29.0576 meters per second)

= 1794.79 seconds

The time interval is given as 0.5 hours, which can be converted to seconds as follows:

Δt = 0.5 hours × 3600 seconds/hour

= 1800 seconds

We can now substitute the values of Δv and Δt into the formula for acceleration.

a = Δv/Δt

= 0/1800

= 0

Therefore, the magnitude of the acceleration that the car experiences is 0.

To calculate the magnitude of the acceleration that the car experiences, we first need to calculate the distance traveled by the car. Using the formula for distance, we can calculate that the distance traveled by the car is 52140 meters. Since the velocity is constant, the change in velocity is 0, which means that the acceleration is also 0. Therefore, the magnitude of the acceleration that the car experiences is 0.

The freezing Point of water is a physical property

The ability of oxygen to react with iron to cause rust is chemical property

Explanation:

The glider's speed just after the skydiver lets go is approximately 39.52 m/s.

To answer this question, we can use the conservation of momentum principle. Before the skydiver lets go, the combined momentum of the glider and skydiver is:

Initial momentum = (mass of glider + mass of skydiver) * initial velocity
Initial momentum = (680 kg + 60 kg) * 38 m/s

When the skydiver releases his grip, the glider's mass is reduced by the skydiver's mass. Let v be the glider's velocity just after the skydiver lets go:

Final momentum = mass of glider * v

Since momentum is conserved:

(mass of glider + mass of skydiver) * initial velocity = mass of glider * v

Now, we can solve for v:

v = [(680 kg + 60 kg) * 38 m/s] / 680 kg

v ≈ 39.52 m/s

Just after the skydiver lets go, the glider's speed is approximately 39.52 m/s.

If the flow is laminar, alpha = 1.0. The alpha factor in the pipe flow energy equation, also known as the Darcy-Weisbach friction factor, accounts for the frictional losses due to fluid viscosity and turbulence in the pipe. Here option D is the correct answer.

The "alpha" factor in the pipe flow energy equation accounts for the velocity profile across the pipe. It is defined as the ratio of the average velocity to the maximum velocity in the flow, and its value depends on whether the flow is laminar or turbulent.

For laminar flow, the value of alpha is 1.0, while for turbulent flow, the value of alpha is approximately 1.05. This is because the velocity profile for turbulent flow is flatter than for laminar flow, resulting in a slightly smaller alpha value.

It is worth noting that the "alpha" factor does not account for variable density. This is taken into account by the Reynolds number, which is a dimensionless quantity that characterizes the flow regime and is defined as the ratio of inertial forces to viscous forces.

Complete question:

Which of the following is true about the "alpha" factor that is in front of the velocity terms in the pipe flow energy equation?

Alpha accounts for the velocity profile across the pipe.

A - If the flow is laminar, alpha = 2.0.

The period of the race car's motion around the circular racetrack is approximately 0.01664 seconds.

The period of motion is the time it takes for an object to complete one full revolution or cycle. In this case, the race car is moving in a circular path, and we can calculate the period using the formula \(T = 2\pi r/v\), where T is the period, r is the radius of the circular path tangential velocity, and v is the velocity of the race car.

First, we need to convert the radius from millimeters to meters:

T is the period of motion,

R is the radius of the racetrack, and

v is the velocity of the race car.

Given that the radius of the racetrack is 265 mm (0.265 m) and the velocity of the race car is 40.0 m/s, we can substitute these values into the formula:

\(T = (2 * \pi * 0.265 m) / 40.0 m/s.\)

Simplifying the equation:

T = 0.01664 s.

Therefore, the period of motion for the race car is tangential velocity approximately 0.01664 s seconds. This means that it takes approximately0.01664 s seconds for the race car to complete one full lap around the circular racetrack.

The median depth of the sinusoidal function is 14m represents the average or middle value of the water depth over one complete cycle.

To determine the period and median depth of the sinusoidal function that relates time and water depth at the ocean port, we need to analyze the given information.

The period of a sinusoidal function represents the time it takes for one complete cycle. In this case, the period would be the time it takes for the water depth to repeat its pattern.

Given that the maximum depth of 20m occurs at 8:00 am and the minimum depth of 8m occurs 6.2 hours later, we can calculate the period as follows:

Period = Time for one complete cycle = Time of minimum depth - Time of maximum depth

Period = 6.2 hours

Finally, the period of the sinusoidal function is 6.2 hours.

The median depth represents the average or middle value of the water depth over one complete cycle. To find the median depth, we can calculate the average of the maximum and minimum depths:

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward the another magnet (Magnet 1) that cannot move. The potential energy in the system of magnets increases because Magnet 2 moves against the magnetic force.

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or the other factors.

Common types of the potential energy include the gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is joule, which has the symbol J.

Potential energy is associated with the forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and the final positions of the body in space.

Explanation:

If the cyclist doubles her speed to 10 m/s, she will use 4000 J of energy to cycle 1 km

When an object is moving, it has kinetic energy, which is defined as the energy it possesses due to its motion. The amount of kinetic energy depends on the mass of the object and its speed. In the case of cycling, the amount of energy a person uses to cycle a certain distance depends on their speed, the weight of the bike, and the resistance of the terrain.

To answer the question, let's assume that the cyclist initially cycled 1 km at a speed of 5 m/s. The energy she used can be calculated using the formula:

Kinetic energy = 0.5 x mass x velocity^2

Let's assume that the cyclist and her bike have a combined mass of 80 kg. At a speed of 5 m/s, her kinetic energy can be calculated as:

Kinetic energy = 0.5 x 80 kg x (5 m/s)^2 = 1000 J

Now, if the cyclist doubles her speed to 10 m/s, her kinetic energy will increase. We can calculate her new kinetic energy as follows:

Kinetic energy = 0.5 x 80 kg x (10 m/s)^2 = 4000 J

Therefore, if the cyclist doubles her speed to 10 m/s, she will use 4000 J of energy to cycle 1 km. This is four times the amount of energy she used when she cycled at a speed of 5 m/s.

The frequency of a sound wave affects the way our ears perceive sound:

1) A sound wave is created when an object vibrates and causes the molecules in the surrounding medium (such as air or water) to vibrate.

2) The frequency of a sound wave is the number of times that the object vibrates back and forth per second. This frequency is measured in hertz (Hz).

3) When a sound wave reaches our ears, it causes the eardrum to vibrate.

This vibration is then transmitted to the inner ear, where it is detected by hair cells in the cochlea.

4) The cochlea is a fluid-filled structure in the inner ear that contains hair cells that are sensitive to different frequencies of sound.

5) Hair cells in the cochlea that are closest to the entrance of the ear are most sensitive to high-frequency sounds, while hair cells at the other end of the cochlea are most sensitive to low-frequency sounds.

6) When a sound wave enters the ear, it causes the fluid in the cochlea to vibrate.

This vibration causes the hair cells that are sensitive to that frequency to bend.

7) The bending of the hair cells generates an electrical signal that is transmitted to the brain via the auditory nerve.

8) The brain then interprets the electrical signals from the hair cells as sound.

The frequency of the sound wave determines the pitch of the sound that we hear, with higher frequencies being perceived as high-pitched sounds and lower frequencies being perceived as low-pitched sounds.

In summary, the frequency of a sound wave determines which hair cells in the cochlea are activated, which in turn determines the pitch of the sound that we hear.
