The units (U) of velocity acceleration and force in two systems are related as under: (a) U'_(V) = (alpha^(2))/(beta)U_(V) , (b) U'_(a) = (alpha beta)U_(a) (c) U'_(F) = [(1)/(alpha beta)]U_(F) All the primed symbols (U) belong to one system and unprimed ones (U) belong to the other systems. alpha and beta are dimensionless constants. How momentum units of the two systems are related?

Let F(alpha)=[[cos alpha,-sin alpha,0sin alpha,cos alpha,00,0,1]], where alpha in R Then (F(alpha))^(-1) is equal to F(alpha^(-1)) b.F(-alpha) c.F(2 alpha)d.-[[1,11,0]]

A silver cup is plasted with silver by passing 0.001 F of electricity . The amount of Ag deposited is (Ag = 107.8)

The focal length of a mirror is given by (1)/(v)-(1)/(u)=(2)/(f). If equal errors alpha are made inmeasuring u and v. Then relative error in f is

Let f(u) be a continuous function and for any real number u.let [ul denote the greatest integer less than or equal to u.Show that for any x>1int_(1)^(x)[u]([u]+1)f(u)du=2sum_(i=1)^(x)i int_(i)^(x)f(u)du

A stone of weight W is thrown straight up from the ground with an intial speed u. If a drag force of constant magnitude f acts - on the same through out its flight , the speed of stone just before reaching the ground is (1) usqrt((W-f)/W) (2) usqrt((W+f)/f) (3) u sqrt((W+f)/(W-f)) (4) u sqrt((W-f)/(W+f))

The restoring force and P.E. of a particle executing a S.H.M. are F and U respectively when its displacement is x. The relation between F, U ad x is
