When you are playing pool and a moving ball hits a stationary ball and the moving ball stops what happens to the momentum of the moving ball?
When a moving pool ball hits a stationary ball, some kinetic energy from the moving pool ball is transferred to the stationary ball and it attains momentum.
Both in the case of elastic and inelastic collisions, momentum is preserved. That means the total momentum will always be the same.
Momentum (ρ) is defined as "mass in motion". There are two factors affecting the momentum. Mass(m) and velocity(v).
ρ = m×v
So for a stationary object momentum will be 0. When the moving ball hits the stationary ball, it starts moving, because it gets kinetic energy from the moving ball. The total momentum before and after the collision will always be equal.
mₐ₁× vₐ₁ = mₐ₂×vₐ₂ + m₂ v₂
mₐ₁× vₐ₁ is the momentum of ball A before the collision
mₐ₂×vₐ₂ is the momentum of ball A after collision
m₂ v₂ is the momentum of ball B after collision.
So the stationary ball begins to move after the collision due to increased kinetic energy and attains some momentum. The total momentum of the system remains the same.

the equivalent capacitance is a. 9 μf b. 6 μf c. 3 μf d. 2 μf e. 1 μf
The equivalent capacitance is 21 μF.
In electrical engineering, equivalent capacitance often abbreviated as C eq—is a measurement of the total combined electric charge held in two or more capacitors connected in series or parallel. A capacitor is an electrical device that stores electrical energy into the electric field. Typically, a capacitor has two electrical leads that are separated by a dielectric or other insulating substance.
We are given that,
capacitance =c₁ =9 μF
capacitance = c₂ =6 μF
capacitance = c₃ = 3 μF
capacitance = c₄ =2 μF
capacitance = c₅ = 1 μF
Thus If the capacitor is connected in parallel the equivalent capacitance, cₐ can be calculated by the equation,
cₐ= c₁+c₂+c₃+c₄+c₅
cₐ = 9 +6 +3 +2+1 μF
cₐ = 21 μF

What is the velocity of a wave that has a wavelength of 3.0 m and a frequency of 12 Hz?
It travels at a speed of 36 meters per second
The velocity of a wave is a measure of how fast the wave travels through a medium. It is given by the equation v = λf, where v is the velocity, λ is the wavelength, and f is the frequency. In this case, the given wavelength is 3.0 meters and the given frequency is 12 Hertz.
Plugging these values into the equation, we can calculate the velocity of the wave:
v = (3.0 m) * (12 Hz) = 36 m/s.
This means that the wave travels at a speed of 36 meters per second.
It is important to note that the velocity of a wave depends on the properties of the medium through which it is traveling, as well as the wavelength and frequency of the wave itself.

two drivers make 100-km trips. Driver 1 complets the trip in 2 hours. Driver 2 takes 3 hours but stops for an hour halfway. which driver has a greater average speed? Explane
Answer:
Driver 1
Explanation:
In this scenario, driver 1 has a greater average speed than driver 2. To determine the average speed of a driver, we need to divide the distance traveled by the time it took to travel that distance. In the case of driver 1, who traveled 100 km in 2 hours, their average speed would be 100 km / 2 hours = 50 km/hour. For driver 2, who traveled 100 km in 3 hours but stopped for an hour halfway, their average speed would be 100 km / (3 hours - 1 hour) = 33.33 km/hour. Since 50 km/hour is greater than 33.33 km/hour, driver 1 has a greater average speed.
the plate area of a parallel-plate capacitor of capacitance c is doubled and the distance between the plates is halved, so that the volume of the dielectric remains the same. the new capacitance of the capacitor is
The new capacitance of the capacitor is Cf = 4Ci is the correct answer.
What is capacitance?Capacitance is an electrical property of a material or system that is related to the amount of charge it can store in an electric field. It is measured in Farads (F), which is the ratio of the electric charge stored on a capacitor to the applied voltage. In other words, it is an expression of the ability of an electrical system or component to store energy in the form of an electric field. It is an important factor in the design of electrical systems, and can be used to control the flow of electric current in circuits. It is also used to measure the amount of voltage that a capacitor can sustain before its capacitance decreases.
Using the Capacitance theorem
Given:
Capacitance of Parallel Plate Capacitor = C
Area = 2A
Distance = 1/2d
Volume of the dielectric remains the same.
New Capacitance =?
1. Initial Capacitance can be written as:

A free-body diagram for the ball at an instant in time is shown in Figure 2. The magnitude of the tension force is also indicated in Figure 2. Which of the following equations represents the centripetal acceleration of the ball if its tangential speed is increased to 2vo ?
The centripetal acceleration of the ball if its tangential speed is increased to 2 v₀ is (4 M v₀²)/R.
The centripetal force equation that we are aware of is
F = (m* v²)/r ----(1)
where,
m is the of the ball
v is the velocity
r is the radius
We are aware that F = m* a ----(2)
Equating (1) and (2), we have,

where, a is centripetal acceleration
In this problem, it is said that, the tangential speed is increased to 2 v₀, then the centripetal acceleration

The greatest acceleration the man can give the airplane is 6.102*10^-3 m/s^2
What is a frictional force ?
The force produced when two surfaces slide past one another and make contact is known as frictional force. The surface texture of these forces and the amount of force pressing them together have the biggest impact.
Mass of the person
m1 = 93kg
Mass of the air plane
m2 = 118000 kg
Coefficient of static friction between the shoes of the person and floor
μs=0.79
Acceleration due to gravity
g=9.8m/s^2
The maximum force the person can apply on the floor is equal to his weight
F = w = m1∗g
= 93∗9.8=911.4 N
The maximum frictional force he can get from the floor is the product of coefficient of static friction and normal reaction
Ff = μs∗N

When a ball at a billiard table hits another ball it is an example of elastic collision?
The collision of two billiard balls is an example of elastic collision.
An elastic collision is a collision where Kinetic energy is preserved. In this type of collision, there will be no change in overall kinetic energy and momentum.
An inelastic collision is where the Kinetic energy is not preserved. Here some of the kinetic energy is transferred to some other form of energy like thermal energy or sound energy.
In both type of collisions, momentum is preserved. There are fewer examples of perfectly elastic collision in real life. Collisions in atomic levels are examples of perfectly elastic collisions. But some collisions where the energy loss is negligible are considered elastic collisions. One such example is the collision of the billiard balls.

Sliding friction is significantly less than static friction for a pair of specified surfaces. because moving an object in motion is simpler than moving an object at rest.
Why do sliding and static friction differ?Contact points are not given enough time to fully interlock while sliding. thus, less friction. But because the surfaces interlock so effectively while the object at rest, friction increases. The difference between static and sliding friction is thus explained.

Any of the button-like ends of axons through which axons create synaptic connections with other nerve cells or with effector cells is known as an axon terminal. Neurotransmitter-containing synaptic vesicles bind at the axon terminal. The cell opens up to calcium ions upon activation by a graded potential or by an action potential of the presynaptic neuron. This starts a chain reaction that leads to the synaptic vesicles fusing into the axon terminal membrane. The synaptic vesicle proteins that the calcium ions activate create fusion holes that allow the neurotransmitters to leave.

0.02x = 0.1 ( 100 - ( 5 + x ) )
0.02x = 0.1 ( 100 - 5 - x )
0.02 x = 10 - 0.5 - 0.1x
0.12 x = 9.5
x = 9.5 / 0.012
x = 79.2 cm
