What is the average speed of a person who swims 105m in 70s ?

v = 1.5 [m/s]

Explanation:

This problem can be solved using the definition of velocity which is the relationship between space and time.

v = x/t

where:

v = speed [m/s]

x = distance = 105 [m]

t = time = 70 [s]

v = 105/70

v = 1.5 [m/s]

i wanna say it’s between b and d, leaning more towards b.

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.
