Answer from: monnn91351

The given statement about the nuclear reaction as three (alpha decay, beta decay and fusion) is false.

Option B

Explanation:

The branch of the study of the nucleus is known as nuclear physics. There are four types of nuclear reaction namely,

1. Fission

2. Fusion

3. Nuclear Decay

4. Transmutation

As the name suggests, when two or many parts of the nucleus fuse together, it is a nuclear fusion reaction. And when one nucleus is divided or splits into two or many parts separately, it is the nuclear fission reaction.

In nuclear decay, the unstable isotope of the element is automatically converted to the new element by ionizing radiation whereas its reverse process called transmutation.

Answer from: Quest

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
