An amplitude modulation transmitter radiates 20 kw. if the modulation index is 0.7, find the magnitude of the carrier power?

carrier power is 16.1 kW

Explanation:

given data

power transmit P = 20 kW

modulation index m = 0.7

to find out

carrier power

solution

we will apply here power transmit equation that is express as

  ...............1

put here all value in equation 1  we get carrier power

solve it we get

carrier power = 16.1

so carrier power is 16.1 kW

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

photocells convert light energy to electricity
