_____ is a bat specialist.

Write true or false: Salim Ali was a specialist of Chimpanzees.

A cricket ball of mass 0.5 kg, moving at 30 m cdot s^(-1) , hits a bat perpendicularly and rebounces with a velocity of 20 m cdot s^(-1) . Impulse of the force exerted by the ball on the bat is

A cricket,ball of mass 150gm is moving with a velocity of 12 m//s and is Hit by a bat so that the ball is turned back with a velocity of 20m//s . The force of the blow acts on the ball for 0.01 sec. Find the average force exerfed on the ball by the bat.

Define impulse. A cricket ball of mass 150 g moving with speed 12 m cdot s^(-1) is hit by a bat so that the ball is turned back with a velocity of 20 m cdot s^(-1) . Calculate the impulse received by the ball.

Wings of bat and insect show

Besides bats, echolocation also occurs in

Human hand, wings of bat and flipper of whale represent

Discuss how wings of bat and birds indicate convergent evolution.

A cricket ball of mass 125 g, moving horizontally at 30 m cdot s^(-1) is hit by a bat and then it moves in the opposite direction at 20 m cdot s^(-1) . If the collision takes place for (1)/(20) s, find the force exerted by the bat.

A ball moving at 30 m/s towards south is hit by a cricketer by his bat. As a result, the ball moves towards north at 20 m/s. What is the change in velocity ? If the collision lasts for 0.02s , what is the acceleration?
