Answer:
the electric field is proportional to the voltage divided by the separation of the plates,
Explanation:
This parallel plate configuration is widely used, as it creates a uniform electric field between the plates. Where the potential and field differences are related by
DV = E d
That is, the electric field is proportional to the voltage divided by the separation of the plates, in general all these configurations are called capacitors
I creating another composite to jump one-quarter as high as the initial composite you most bear in mind factors of weight,hardness ,center of mass will be one-quarter of the prior composite in other for it to bounces only one-quarter .
From the question we are told
A composite when tested bounces half as high as the original material. How can you create another composite that bounces only one-quarter as high
Generally We know that
A composite Material is a material that is made up of more than be substance i.e is it requires substance of variant properties and make up to come together to form it.
Therefore
I creating another composite to jump one-quarter as high as the initial composite you most bear in mind factors of weight,hardness ,center of mass will be one-quarter of the prior composite in other for it to bounces only one-quarter

Answer:
Ratio of power produced by new to old car is 16:1
Explanation:
Assuming both cars have the same mass m
Let KE1 and KE2 be the kinetic energies of the old and new car respectively.
v1 = v
and v2 = 4v
KE1 = 1/2mv1² = 1/2mv²
KE2 = 1/2mv2² = 1/2m(4v)² = 1/2×m×16v² = 8mv²
Ratio of the power produced by the new car to the old one is simply KE2/KE1 =8mv²/1/2mv² = 16
Since the same time interval is given.
B) 20 cm
The height and distance will be the same. Only the image will be laterally inverted.
B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.
Hope this helps!! :)
