A man of mass 100 kg stands at the rim of a turn table of radius 2 m and moment of inertia 4000 kg m² mounted on a vertical frictionless shaft at its centre. The whole system is initially at rest. The man now walks along the outer edge of the turnable with a velocity of 1 m/s relative to the earth.

Detailed Solution

Cancer is one of the most dreaded diseases of human beings, and is a major cause of death all over the globe.

There are so many techniques to detect cancer. Techniques such as radiography (use of X-rays), CT (computed tomography ) and MRI (magnetic resonance imaging) are very useful to detect cancers of internal organs. Computed tomography uses X-rays to generate a three-dimensional image of the internals of an object. MRI uses strong magnetic fields and non-ionising radiations to accurately detect pathological and physiological changes in living tissue.

Among these techniques, MRI is one of the safest techniques as the risk factors are low.
