The antenna for an am radio station is a 77.5 m high tower whose height is equal to one‑quarter the wavelength of the broadcast signal. at what frequency does the station transmit?

this is a good question! i'll do some research and come back when i have the answer!

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
