Answer: 61.2N
F=kq1q2/r^2
F=8.98E9(1.6E-19)(1.6E-19)/(1.93E-15)^2
F=61.2N
If they research it then they would get the answer that they need to find out of the universe that is what I think.

Answer: A wavelength is how long ONE wave is. First divide the distance of the whole diagram by the number of waves. you will get 2m. This is the answer.
<span>a = ΔV/Δt = (5000-10000)/60 = -500/6 = -83.(3) m/sec^2</span>
(h + .16) m g = 1/2 k x^2 total PE of block relative to where it stops
(h + .16) .82 * 9.8 = .5 * 120 * .16^2 PE released = PE of spring
8.04 h + 1.29 = 1.536
h = (1.536 - 1.29) / 8.04 = .031 m = 3.1 cm
