Answer:
Work cause a change in kinetic energy
The volkswagon experiences a greater force as it was hit by a larger object that had a larger mass than itself
Answer:
The amount of charge on the plates is now equal to half its original value
Explanation:
From the question we are told that
The charge on the plate is Q
The initial separation is 
The new separation is 
Generally the capacitance of the capacitor is mathematically represented as
Generally the charge of the parallel plate capacitor is mathematically represented as
=> 
Here 
, A and V are constant , so looking at the question we see that Q varies inversely with d
So
Here K is a constant
so
=> 
=> ![Q_1 d_1 = Q_2 * [2 d_1]](https://tex.z-dn.net/?f=Q_1%20d_1%20%3D%20%20Q_2%20%2A%20%5B2%20d_1%5D)
=> 
So we see from the mathematically relation that the charge of the parallel plate capacitor will reduce by half of it original value

The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.
Answer:
0.025 Meters a second, or 0.025 m/s
Explanation:
So, if we take the information that we know, 1) The wall is 2 meters thick, and 2) it took a total of 0.05 seconds to travel all the way. So, to get our answer, lets divide 0.05 by 2. That lands us with 0.025! This answer makes sense, because we know that sound travels quickest in solids, (Due to sound-waves being a mechanical longitudinal wave, and solids have the densest particle formations, allowing the sound wave to travel swiftly compared to liquids and gases, in which the particles are more spread out.)
