An archer standing on the back of a pickup truck moving at 28 m/s fires an arrow straight up at a duck flying directly overhead. The archer misses the duck! The arrow was fired with an initial velocity of 49 m/s relative to the truck. a. For how long will the arrow be in the air?
b. How far will the truck travel while the arrow is in the air?
c. Where, in relation to the "duckless" archer, will the arrow come down? Will the archer have to 'duck'?

the answer to this question is 60 n

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.

as technology advances, new experiments often expose problems in accepted theories. c
