A cart (mass = 2.7 kg) is pushed and held against a spring such that the spring stores 62.6 joules of energy. Use conservation of energy to determine the speed that the spring can impart to the cart when the cart is released.

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.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
