A3 mg bullet is fired from a 1 kg musket with a velocity of 3,000. m/s. what is the resulting velocity of the musket?

by momentum conservation we can say

since gun and bullet was initially at rest so initial momentum of both must be ZERO

so it will recoil back with speed 9 m/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.
