The initial velocity of a particle is u (at t = 0) and the acceleration f is given by f = at. Which of the following relation is valid?
Find the force of friction acting between both the blocks shown in the figure. u = .4 5 Kg → F= 20 N u = .1 10 Kg
Let u(x) and v(x) satisfy the differential equation (du)/(dx)+p(x)u=f(x) and (dv)/(dx)+p(x)v=g(x) are continuous functions.If u(x_(1)) for some x_(1) and f(x)>g(x) for all x>x_(1), does not satisfy point (x,y), where x>x_(1), does not satisfy the equations y=u(x) and y=v(x) .
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
Assertion : The focal length of the mirrorr is f and distance of the object from the focus is u , the magnification of the mirror is f//u . Reason : Magnification =("Size of the image")/("Size of object" )
If x,F and U denote the dispalcement, force acting on and potential energy of a particle then
If x, F and U denote the displacement force acting on and potential energy of a particle:
A silver cup is plasted with silver by passing 0.001 F of electricity . The amount of Ag deposited is (Ag = 107.8)
