1. Law 1, since there is no other force acting on your body as you stand there, so you will continue to go forward.

2. Law 3, since the swimmer is using opposite forces to propel herself through the water. She generates a force by pushing the water which helps to push her forward.

3. Law 2, since you are giving the motorcycle more energy as a result of the gas being transformed into the energy that helps to accelerate the motorcycle's speed.

3241004551 [841]

Answer:

option A

Explanation:

given,                    

angular speed is constant

initial distance = r                

final distance (r')= 2 r

initial linear velocity = v

final linear velocity = v'

we know,                  

v = r ω......................(1)

where r is the distance

ω is the angular speed

now,            

v' = r' ω            

v' = 2 r ω        

v' = 2 v                

hence, the linear velocity doubles.

The correct answer is option A
