Answer:
f = 400 / 5 s = 80/sec frequency of revolution
P = 1/f = 1/(80/sec) = .0125 sec period of revolution
Gravity pulls objects down to the earth
Energy of gamma rays is given by equation

here we know that
h = Planck's constant

now energy is given as


now by above equation



now for wavelength we can say



Answer:
10 N
Explanation:
F = ma = m(Δv/t) = 5.0(10.0 - 0)/5.0 = 10 N
