3 semicircular canals located above utricle lie –

A particle of mass 2 kg starts moving in a straight line with an initial velocity of at a constant acceleration of . Then rate of change of kinetic energy

A car of mass 1000 kg moves at a constant speed of up an incline. Assume that the frictional force is 200 N and that where, is the angel of the incline to the horizontal. The . Find the power developed by the engine

The work done in dragging a stone of mass 100 kg up an inclined plane 1 in 100 through a distance of 10 m is (take )

Statement ITwo particles moving in the same direction do not lose all their energy in a completely inelastic collision.
Statement IIPrinciple of conservation of momentum holds true for all kinds of collisions.

If momentum is increased by 20%, then kinetic energy increases by

A spring gun of spring constant 90 is compressed 12 cm by a ball of mass 16 g. If the trigger is pulled, the velocity of the ball is

The minimum velocity (in ) with which a car driver must traverse a flat curve of radius 150 m and coefficient of friction 0.6 to avoid skidding is

Read the two reaction A and B given below and select the correct option accordingly
A) ADP + Pi ATP
B) ATP ADP + Pi

Therefore the correct option is choice 1

A parallel plate capacitor of area A, plate separation d and capacitance is filled with three different dielectric materials having dielectric constants as shown. If a single dieletric material is to be used to have the same capacitance is this capacitors, then its dielectric constant is given by

A body weight 8 g when placed in one pan and 18 g when placed on the other pan of a false balance. If the beam is horizontal when both the pans are empty. The true weight of the body is

If a body of mass is carried by a lift moving with an upward acceleration , then the forces acting on the body are (i) the reaction on the floor of the lift upwards (ii) the weight of the body acting vertically downwards. The equation of motion will be given by

The equation of motion of a particle moving along a straight line is , where the units of s and t are cm and sec. The acceleration of the particle will be zero after

Assertion : First law of thermodynamics is not adequate in predicting the direction of a process
Reason : Total energy of universe is constant.
