What best describes the relationship of the wavelengths in the electromagnetic spectrum?
A
Microwaves are shorter than visible light waves.

B
Gamma rays are longer than ultraviolet rays.

C
Radio waves are shorter than gamma rays.

D
Infrared waves are longer than X-rays.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

explanation:

could i give you a exaplo that could you?

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
