(c)Both (a)and (b)
(d)none of these
HEN​

Answer 1

Answer:

option d because force depend on rate of change of momentum

Answer 2

The right response is (c) both (a) and (b).

• Any influence that results in a change in how an object moves is referred to as force. A force that is exactly proportional to the rate of momentum change is applied to an object when its momentum changes.

• In other words, the force is determined by dividing the change in momentum by the amount of time it took for the change to take place. This implies that the force is proportional to the magnitude of the change in momentum and the rate at which it happens.

• Newton's second rule of motion, which says that the force exerted on an object is equal to the rate of change of its momentum, describes this link between force, momentum, and time. Hence, force is a function of both the change in momentum and the speed at which that change occurs.

• The distinction between a push and a pull, as well as between a force that is in touch with another object and one that is not, must be made. Friction, tension, and normal forces are examples of contact forces, whereas gravity, electric, and magnetic forces are examples of non-contact forces.

• Many branches of physics, such as mechanics, electromagnetic, and thermodynamics, depend critically on an understanding of the connection between force and momentum.
