Pliz answer my question, start from Qno:15

15 -differences between gymnosperms and angiosperms:

16-

17- Uniform acceleration is a change of equal velocity in equal interval of tine.

Non- Uniform acceleration is a change of unequal velocity in equal interval of time.

18- Three equation of motion:

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.

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
