A particle after starting from rest experiences constant acceleration for \(20 {~sec}\). If it covers a distance \(s_{1}\) in the first \(10 ~{sec}\), then the distance covered during the next \(10~ {sec}\) will be:

In YDSE, the slit widths are in the ratio of \(1:\) 9. The ratio of intensity of the maxima to that of the minima is:

The relation between radius of curved road and banking angle is:

The work done in an isothermal expansion of a gas depends upon:

Which one of the following is not the unit of energy?

In a double slit experiment, instead of taking slits of equal widths, one slit is made twice as wide as the other. Then, in the interference pattern:

The magnetic field intensity inside the toroid is B. If the current in the toroid is doubled then the magnetic field intensity inside the toroid will become:

A block of mass \(2\) kg rests on a rough inclined plane making an angle of \(30^\circ\)with the horizontal. The coefficient of static friction between the block and the plane is \(0.7\). The frictional force on the block is:

Film coefficient is defined as Inside diameter of tube:

A block of mass \({m}=4 {~kg}\) undergoes simple harmonic motion with amplitude \({A}=6 {~cm}\) on the frictionlesssurface. Block is attached to a spring of force constant \({k}=400 {~N} / {m}\). If the block is at \({x}=6 {~cm}\) at time \({t}=0\)and equilibrium position is at \(x=0\) then the blocks position as a function of time (with \(x\) in centimetres and \(t\)in seconds)?
