3. how much work is done on a small car if a 3150 n force is exerted to move it
75.5 m to the side of the road?

W = 237825 J

Explanation: Work is defined as "a force causing movement or displacement of an object":

W = F*d

where W is the work, F is the force and d is the distance, and in this casewe have:

F = 3150 N

d = 75.7 m

W = 3150N*75.5m = 237825 J

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq
