Miss Y agreed to keep a request from her friend to cook rice in an aluminium pot. A metal

cover was used on the top of the aluminium pot during cooking, but after a short while, the

metal cover was fallen down. They involved in a debate to explain it using a theorem of physics

why the metal cover has been fallen down from the top of the aluminium pot. Miss Y said that

it was due to produced pressure but her friend agreed on it to some extent and also asked about

the conversion of energy, demanding to show the expression for the theorem. Could please

help Miss Y?

1.As a smart physics student,mention a law of physics which is very important to you?Explain with an example why do u think that the law is very important.

2.Say,Mr X runs on a plain land and jump from a spot in forward direction.Recognize and describe his jumping motion through an equation and make an argument for your answer.

One day a teen boy went out of their house and stood beside a pond. He threw a small rock in the pond relatively far from him and found that a nice wave was coming toward him. He felt a lovely moment. He threw another similar stone in the pond relatively close to him. He found that the first wave was disturbed and was not coming to him smoothly. He tried to understand, ‘why did it happen?’ but failed and become unhappy. How will you explain this incidence in details to the boy to make him so happy? Please mention the principle involved in the incident and explain different cases of its applications.

A 0.140-kg baseball is dropped and reaches a speed of 1.20 m/s just before it hits the ground. It rebounds with a speed of 1.00 m/s. What is the change of the ball's momentum?

You throw a ball vertically upward from the roof of a tall building. The ball leaves your hand at a

point even with the roof railing with an upward speed of 15.0 m/s; the ball is then in free fall. On its

way back down, it just misses the railing. Find (a) the ball’s position and velocity 1.00 s and 4.00 s

after leaving your hand; (b) the ball’s velocity when it is 5.00 m above the railing; (c) the maximum

height reached; (d) the ball’s acceleration when it is at its maximum height.

. A particle moves a fixed point O. The velocity v of the particle at time t s is given by v = (3t − 2)(t − 4) and s . A particle moves a fixed point O. The velocity v of the particle at time t s is given by

v = (3t − 2)(t − 4) and s = 8m when t = 1s, find:

(a) the initial velocity of the particle [1]

(b) the acceleration of the particle when t = 3s. [2]

(c) the values of t when the particle is at rest [2]

(d) the distance the particle is from O when t = 2s. [5]

(e) the distance travelled when t = 2s= 8m when t = 1s, find: (a) the initial velocity of the particle [1] (b) the acceleration of the particle when t = 3s. [2] (c) the values of t when the particle is at rest [2] (d) the distance the particle is from O when t = 2s. [5] (e) the distance travelled when t = 2s
