Tension in the cable supporting an elevator, is equal to the weight of the elevator. From this, we can conclude that the elevator is going up or down with a

The total mass of an elevator with a 80 kg man in it is 1000 kg. This elevator moving upward with a speed of 8 m//sec, is brought to rest over a distance of 16m. The tension T in the cables supporting the elevator and the force exerted on the man by the elevator floor will respectively be-

Boiling point elevation is

The force exerted by the floor of an elevator on the foot of a person standing there is more than the weight of the person if the elevator is :

(A) : The apparent weight of a body in an elevator moving with some downward acceleration is always less than the actual weight of body. (R) : Normal reaction force by the floor of elevator on the body is less than the weight of the body when elevator is moving down

A person standing oin the floor of an elevator drops as coin. The coin reaches the floor of the elevator in a time t_1 if the elevator is stationary and in the t_2 if it is moving uniformly. Then

A man is standing on a weighing machine kept on the floor of an elevator. The ratio of measured weight of the man when elevator is at rest and when it is moving with downward acceleration a is 3 : 2. The value of a is :

A collision experiment is done on a horizontal table kept in an elevator. Do you expect a change in the results if the elevator is accelerated up or down because of the noninertial character of the frame?
