Fthe sun blows up at some instant and four minutes later we on earth sit down to eat lunch, those two events are separated by a spacelike interval. the sun's blowup cannot possibly have influenced us at the time we sat down, because it takes 8 minutes for light to reach us from the sun. and since the interval is spacelike, there must be a reference frame in which the two events are simultaneolls. find the speed of this frame relative to the sun-earth rest frame.

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.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
