Radio signals travel at a rate of 3 × 10^8 meters per second. how many seconds would it take for a radio signal to travel from a satellite to the surface of the earth if the satellite is orbiting at a height of 3.6 × 10*7 meters?

a.) 8.3 seconds
b.) 1.2 × 10^–1 seconds
c.) 1.08 × 10^16 seconds
d.) 10.8 × 10^15 seconds

B. 1.2x10^-1 seconds

Explanation:

a and c

c is 100% but i am confused in a

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
