The strength of electric field E is 17 N / C.
<u />
<u>Explanation:</u>
Electric field strength is defined as the force per unit charge acting at a point in the given field. The equation for the strength of the electric field is given by
E = F / q
where E represents the electric field strength,
F represents the force in newton,
q represents the charge in coulomb.
Given the charge q = 0.30 coulombs
force F = 5.0 N
Electric field strength E = force / charge
= 5.0 / 0.30
E = 16.66 = 17 N / C.
The kinetic energy is
![\frac 1 2 m v^2](https://tex.z-dn.net/?f=%5Cfrac%201%202%20m%20v%5E2)
and the height of the building doesn't matter at all.
![E = \frac 1 2 m v^2 = \frac 1 2 (2)(5)^2 = 25](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%201%202%20m%20v%5E2%20%3D%20%5Cfrac%201%202%20%282%29%285%29%5E2%20%3D%2025)

However instead of crests and troughs, longitudinal waves have compressions and rarefactions. Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
