Which scenario represents the strongest force? (Assume particles in all scenarios are the same distance apart.) a) Protons and n
eutrons are held together inside the nucleus. b) Two particles are attracted to one another by static electricity. c) An unstable atom breaks down releasing two radioactive particles. d) Two rocks of equal mass fall to the ground at the same speed.
a) Protons and neutrons are held together inside the nucleus
Explanation:
There are four forces which are responsible for all the observations in the nature. These forces are called fundamental forces of nature and listed below:
i) Gravity
ii) Electromagnetism
iii) Weak nuclear force
iv) Strong nuclear force
Among these four, strong nuclear force is strongest one. It has also been observed that when we split nucleus, heat and energy released are larger than any other force. Hence, option (a) will be correct.
The force of attraction existent between the proton and neutron in the nucleus of an atom is extremely large. When the nucleus splits there is a large release of heat and energy larger than the force present in any of the other options listed.
Since the angular acceleration is assumed to be constant, and the wheel's angular speed is increasing from rest (0 rad/s) to 0.4π rad/s within 23.8s. Then the angular acceleration must be
