A person standing on the floor of an elevator drops a coin. The coin reaches the floor in time `t_1` if the elevator is at rest and in time `t_2` if the elevator is moving uniformly. Then

A

`t_1=t_2`

B

`t_1ltt_2` or `t_1gt t_2` depending upon whether the lift is going up or down

C

`t_1lt t_2`

D

`t_1gt t_2`

A person standing on the bank of a river observes that the angle of elevation of the top of a tree standing on the opposite bank is 60^(@) . When he moves 40 m away from the bank, he finds the angle of elevation to be 30^(@) . Find the height of the tree and the width of the river. (sqrt3=1.73)

Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time t_1 . On other days. if she remains stationary on the moving escalater, then the escalator takes her up in time t_2 . The time taken by her to walk up on the moving escalator will be:

Same quantity of ice is filled in each of the two metal containers P and Q having the same size, shape and wall thickness but made of different materials. The containers are kept in identical surroundings. The ice in P melts completely in time t_1 , whereas that Q in takes a time t_2 . The ratio of thermal conductivities of the materials of P and Q is

A person of mass 60 kg stands on a weighing scale in a lift (elevator). What would the scale read if the elevator moves (i) up with a uniform speed of 5 m//s (ii) down with a uniform acceleration of 4 m//s^2 (iii) up with a uniform acceleration of 4 m//s^2 ? [Given : g = 10 m//s^2 ]

A simple pendulum attached to the ceiling of a stationary lift has a time period T. The distance y covered by the lift moving upwards varies with time t as y = t^(2) where y is in metres and t in seconds. If g = 10 m//s^(2) , the time period of pendulum will be

A projectile can have the same range R for two angles of projection. If t_1 and t_2 are the times of flight in the two cases, then the product of the two time of flight is proportional to A. R^2 B. frac(1)(R^2) C. frac(1)(R) D. R

The figure shows the elliptical orbit of a planet about the sun S. An ellipse is the curve obtained when a cone is cut by an inclined plane. It has two focal points. The sum of the distances to the two focal points from every point on the curve is constant. F_1 " and " F_2 are the two focal points of the ellipse . The shaded area CF_1D is twice the shaded area AF_1B. t_1 is the time taken by the planet to move from C to D and t_2 is the time to move from A to B Which laws do we understand from the above diagram and description?
