A car traveled 140 km from El Paso, TX to Dallas, TX in 2 hours. What was the car’s average speed in seconds?

Explanation:

first get the velocity value in km/h

140/2=70km/h

to change the value (kilometers per hour) to meters per second divide by 3.6

70/3.6=19.44m/s

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.

less than one you can't create energy
