Subtract. What is the difference (9 * 10"") - (4 * 10 ") in scientific
notation?
(9 * 1010) – (4 * 1019 = ? * 100
10
DONE

(5 * 10")

Step-by-step explanation:

9-4 = 5

I don't understand the "" part but im pretty sure this is what you meant

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

step-by-step explanation:

1. practice, practice & more practice
