Answer 1

Explanation:

Derive the equation S="4 using velocity time graph.

(b) The brakes applied to a car produces an acceleration of 6 m/s in the opposite direction to

motion if the car takes 2s to stop, after the application of brakes, calculate the distance it

travels during this time.

33. Differentiate between

(a) Gymnosperm and Angiosperms (any three)

(6) Aves and reptilia (any two)

Or

(a) What is ozone layer? Name the compound by which it is depleting. How can it be controlled

(b) What are weeds? Give example.
