1. While exploring sea life, a biologist went under water and on land. He recorded the depths above and below sea level where he found different creatures. Creature Depth above or below sea level
Hermit crab 2 ft
Clam 0 ft
Snapper ft

Redfish ft

(a) List these creatures in order from deepest to highest.
(b) Write a comparison statement for the depth of the hermit crab and the redfish.

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.
