8. which of the following best describes an
object with constant velocity?

a = 0

Step-by-step explanation:

The answer choices were found else where.

To have a constant velocity, we need to have an acceleration that is equal to 0. This is because if we have a sudden movement it will make the line on a graph go up dramatically then after the acceleration, the line will go back down because the velocity will drop. That will cause the velocity not to be consistent and in this case we need it to be.

Best of Luck!

90% rotation

step-by-step explanation:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
