Person receives more injuries when he falls on marble floor than that on sand. This is because On marble floor the linear momentum is reduced to zero in less time

In sand the linear momentum is reduced to zero in less time

Acceleration due to gravity is more in case of marble floor

Acceleration due to gravity is less in case of sand

A40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the. volume of the ammonia if it’s pressure is changed to 8.4 kpa while its temperature remains constant.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
