Radius of gyration, on the other hand, has a relationship with moment of inertia however it is defined as the square root of moment of inertia divided by the system's mass. This number gives you a distance from the axis of rotation at which there is an equal moment of inertia than that of the entire system.

Nuclear force as explained above

1Thank You

Yogita Ingle 5 years, 6 months ago

Nuclear force is the strongest force in the nature .

The particles inside the nucleus are charged particles (protons) and neutral particles (neutrons) which are bounded to each other by a strong interaction called nuclear force or strong force. Hence, they may be defined as the forces binding the nucleons (protons and neutrons) together in a nucleus. These are responsible for the stability of the atomic nucleus.

Rohit Krishna 5 years, 6 months ago

It helps you to answer questions easier than you expected,If you are confused about the answer to a question,you can simply use the dimensional formula to get to the answer.Bit it can't always be applied if two or more options having same dimensions are given. For eg:You are asked to find the work done in a giben situation.But you are unable to get to the answer due to some errors in intervening steps.In such cases,you can apply dimensional formula to arrive at the answer and equate the formula to the dimensions of work, if and only if all the options have different dimensions.

What is the origin of electromagnetic force and strong nuclear force?

Posted by Nemha Chala 5 years, 6 months ago

Sia ? 4 years, 5 months ago

The electromagnetic force is a long range force which acts of charged particles. Like charges repel and unlike charges attract.

The colour force binds quarks together. It binds three quarks to make a baryon such as a proton or neutron. It binds two quarks to make a meson. The strong nuclear force is actually a residual effect of the colour force where quarks in a proton or neutron get bound to quarks in adjacent protons and neutrons. This effectively binds protons and neutrons to make a nucleus.

The weak nuclear force is responsible for radioactive beta decay. It can convert a proton into a neutron, a positron and an electron neutrino. It can also convert a neutron into a proton, an electron and an electron antineutrino.

The strong nuclear force is very short range and can only bind adjacent protons and neutrons. The electromagnetic force is long range. Thus every proton in a nucleus repels every other proton. This is which heavy elements are unstable.

Posted by Aniket Singh 5 years, 6 months ago

1 answers

Sia ? 4 years, 5 months ago

That is when supply voltage V and armature resistance Ra are kept constant, speed is directly proportional to armature current Ia. Thus if we add resistance in series with armature, Ia decreases and hence speed decreases. Greater the resistance in series with armature, greater the decrease in speed.

Abhishek Jha 5 years, 6 months ago

The Scope of Physics Physics is the study of energy, matter, and their interactions. It’s a very broad field because it is concerned with matter and energy at all levels—from the most fundamental particles of matter to the entire universe. Some people would even argue that physics is the study of everything! Important concepts in physics include motion, forces such as magnetism and gravity, and forms of energy such as light, sound, and electrical energy.

Rohit Krishna 5 years, 6 months ago

a=πr^2. Therefore,da/dr=d(πr^2)/dr=2πr. By applying product rule, d(πr^2)/dr=r^2 * d(π)/dr + π *d(r^2)/dr =2πr Note that derivative of pi is zero as it is a constant and the rule d(r^x)/dr= x * r^x-1 applies here
