A bowling ball rolls down the alley and hits a pin. Compare the force exerted by the ball on the pin to the force exerted by the pin on the ball during the collision between the ball and the pin. Is one force larger than the other or are they equal in magnitude to each other? Does this relationship of the two forces change at any time during the collision? Explain please.

The magnitude of the force exerted by the ball on the pin will be equal to the magnitude of the force exerted by the pin on the ball and thus, the relationship doesn't change at anytime. This fulfils Newton's third law of motion.

Explanation:

Newton's third law of motion states that; "For every action, there is an equal and opposite reaction."

This statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Now, applying this to the question,

we can say that: "the magnitude of the force exerted by the ball on the pin will be equal to the magnitude of the force exerted by the pin on the ball and thus, the relationship doesn't change at anytime!

your answer would be fusion

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
