At Deoprayag (Garhwal, UP) river Alaknanda mixes with the river Bhagirathi and becomes river Ganga. Suppose Alaknanda has a width of 12 m,

The moon will begin to move in a straight line in the direction in which it was moving at that instant because the circular motion of moon is due to...

Law of conservation of momentum is applicable to isolated system (no external force is applied). In this case, the change in velocity is due to the gravitational force of earth.

If the average depth of rivers is h meter, then the flow  volume of water in the river Alaknanda =20*h*12000/3600 m³/s  =66.67h m³/s  The flow volume of water in the river Bhagirathi...

In single slit diffraction experiment fringe width is β = 2λD/d If d is doubled, the width of central maxima is halved. Thus size of central maxima is reduced to half. Intensity...
