What does newton's third law say about why momentum is conserved in collisions?

a. equal forces act in equal times, so the change in momentum for both objects must be equal.
b. unequal forces act in unequal times, so the change in momentum for both objects must be equal.
c. unequal forces act in unequal times, so the change in momentum for both objects must be unequal.
d. equal forces act in unequal times, so the change in momentum for both objects must be equal.

Option (A) is the correct answer.

Explanation:

According to Newton's third law of motion, when force is exerted by one body to second body then the  second body will also exert a force equal in magnitude and opposite in direction on the first body.

For example, when we hit a wall with our leg then the wall also applies a force on our leg and thus, our leg gets hurt.

Hence, we can conclude that newton's third law says that momentum is conserved in collisions because equal forces act in equal times, so the change in momentum for both objects must be equal.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
