2. a race car starts at 400 m/s and then stops in 20 seconds. calculate acceleration. acceleration=final velocity - initial velocity/ change in time
a. -20 m/s2
b. 40 m/s2
c. 20 m/s2
d. 55 m/s2

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.

explanation:

the assestment will probley apele with cause and effect

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
