Which of the following is true because of the associative law of multiplication? 2(3⋅4)5=6⋅20 2(3⋅4)5=120 2(3⋅4)5=5⋅4(3⋅2) 2(3⋅4)5=2⋅3(4⋅5)

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.
