The answer is B(There should be always a second force to make an interaction with the other one)2. C It follows Newtons Third Law, when a force is applied it produces an equal amount of force in the opposite direction. But the above option is only correct when the given nail is piercing through the wall if its not then the forces on both hammer and the nail is the same.3. B Her hand is providing a normal force to the apple against the force of gravity.......
9. 2 people, 1 twice as massive as the other, attempt a tug of war with 12 meters of rope on frictionless ice. After a brief time they meet. The heavier person slides a distance of
A) 3m.
B) 4m.
C) 5m.
D) 6m.
1. The answer is B
(There should be always a second force to make an interaction with the other one)
2. C
It follows Newton's Third Law, when a force is applied it produces an equal amount of force in the opposite direction. But the above option is only correct when the given nail is piercing through the wall if it's not then the forces on both hammer and the nail is the same.
3. B
Her hand is providing a normal force to the apple against the force of gravity.
4. While falling there is no reaction force but after the person falls the answer should be B where the Earth pushes against the person.
5. A the force is given by the exhaust gasses on the rocket.
6. A
It is not possible as because the force exerted is equal to mass x acceleration. No the mass of the tissue paper is very small and now in order to create a 50N force u need to punch with a huge acceleration! Which is practically not possible.
7. A less than 3000N
8. C The same as because the car and the bug is a single mass now.
9. D 6m will be the distance
