The position of a particle moving along the X-axis as a function of time t (in seconds) is given by $X = t^{3}-9t + 2$. The magnitude of the acceleration of the particle at $t=3$ seconds is:

A copper and a steel wire of the same diameter are connected end to end. A deforming force F is applied to this composite wire which causes a total elongation of 3 cm. The two wires will have

A mass of 5 kg is moving along a circular path of radius 1 m. If the mass moves with 300 revolutions per minute, its kinetic energy would be:

Light waves entering a medium with higher refractive index undergo

Two inclined frictionless tracks, one gradual and the other steep meet at A from where two stones are allowed to slide down from rest, one on each track as shown in the figure below.

A positive charge +q is located at the center of mass of a cube, sphere and cylinder. The total electric flux through the surface:

Electrical energy is transmitted over large distances at high alternating voltages because:

A vehicle travels half of the total distance (L) with speed $V_1$ and the other half with speed $V_2$, then its average speed over this whole distance is:

A far away object approaches a convergent lens from the left with a uniform speed of $5~m/s$ and stops at the focus. During this time the image on the right moves:
