A baseball has mass 0.147 kg. If the velocity of a pitched ball has a magnitude of 42.0 m/s and the batted ball's velocity is 54.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat.

Explanation:

Given that,

Mass of the baseball, m = 0.147 kg

The initial speed of the baseball, u = 42 m/s

The final speed of the baseball, v = -54 m/s (in opposite direction)

We need to find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. The change in momentum is given by :

We know that the impulse applied to it by the bat is equal to the change in momentum. So, the impulse is 1.764 kg-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.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
