What property of the wave is labeled H?
amplitude
crest
wavelength
trough

Gam radio signals can usually be heard behind a hill, but fm often cannot. that is, am signals bend more than fm. explain. (radio signals, as we shall see, are carried by electromagnetic waves whose wavelength for am is typically 200 to 600 m and for fm about 3 m.)

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
