In the livingroom of your house you would like to run a 300 W stereo, a 30 W computer, a 960 W laser light projector, and two 120 W lights. Assuming your house is wired for 120 Volts, how much current will be pulled by these electrical devices

12.75 A

Explanation:

The total power is 300 + 30 + 960 + 2 × 120 = 1530 W

Electrical power is given by

Then

With a voltage of 120 V,

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.
