Which of these is a good example of Newton's First Law of inertia
Eddi Din [679]

Answer: The correct option is A.

Explanation:

Inertia is a state of an object or body to maintain its state. It resists any change in its state.

Newton's first law of inertia: When an objects is in state of motion, it will remain its state of motion or if it is in state of rest then it will remain in rest unless it is acted upon by external motion.

In the given options, a ball sits motionless on the ground is good example of Newton's first law motion. No external force is acting in this case.

In options (B), (C) and (D) , the external force is acting.

Therefore, the correct option is A.

A student rubs a rubber balloon on their hair for several seconds. The student then rubs a second rubber balloon on her hair for
erastovalidia [21]

Answer:

Option A

Explanation:

In this experiment, when balloon is rubbed on the chair electrons are transferred from the hair to the surface of the balloon thereby making balloon negatively charged and hair positively charged. When two negatively charged balloon are brought close to each other, they repel while when balloon is brought closer to the hair, they attract each other

Hence, option A is correct

A meteor moving through outer space continues to move on the same path until an outside force acts on it
Fittoniya [83]

Newton stated 3 laws that rules moving bodies:

First law - an object remains in its state (resting or moving at constant speed) unless acted upon a force

Second law - the force (F) of an object is equal to its mass (m) multiplied by its acceleration (a); F = m x a

Third law - when an object exerts a force upon another, the second object exerts a force that is equal in magnitude and opposite in direction

So, according to the First Law of Motion, the metor moving through outer space will continues its motion until an outside force acts upon it
