In Fig, the bar is uniform and weighing `500 N`. How large must `W` be if `T_(1)` and `T_(2)` are to be equal?

In figure the bar is uniform and weighing 500 N. How much must be the weight of the block (in N) be if T_(1) and T_(2) are to be equal ?

Determine the tension T_(1) and T_(2) in the strings shown in Fig.

A train is at rest. It accelerates for a time t_(1) at a uniform rate alpha and then comes to rest under a uniform retardation rate beta for time t_(2) . The ratio t_(1)//t_(2) is equal to

The weight W of a certain stock of fish is given by W = nw, where n is the size of stock and w is the average weight of a fish. If n and w change with time t as n = 2t^(2)+3 and w=t^(2)-t+2 , then the rate of change of W with respect to t at t = 1, is

In fig tension in the string that connects the masses A and B is T_(1) and that in the string connecting B and C is T_(2) then T_(1)/T_(2) is:

Two spherical black bodies of radii R_(1) and R_(2) and with surface temperature T_(1) and T_(2) respectively radiate the same power. R_(1)//R_(2) must be equal to
