A jug of orange juice requires 3 cans of orange concentrate and 5 cans of
water.
a) Accidentally, 4 cans of
concentrate were mixed with 5
cans of water. Is the mixture
stronger or weaker than it
should be? Explain.
b) Suppose 6 cans of water were
mixed with 3 cans of
concentrate. Is the mixture
stronger or weaker
than it should be? Explain.

the answer is is 12 bc 4 - 5 - 6 - 3= 12

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.

1/4 because there is 4 grades.
