Nuclear fission experiments show that the neutrons the uranium nuclei into two fragment
of about the same size. This process is accompanied by the emission of several:
If source and observer are moving towards each other with same speed and aftercrossing they are
receding each other then frequency observed by observer:
A body moves a distance of 10 m along a straight line under the action of a force of 5 N. If the work done is 25
joules, the angle which the force makes with the direction of motion of the body is?
Two projectiles โAโ and โBโ are thrown with same speed but at angle of 40 degree and 50 degree with the horizontal. The horizontal range of โAโ will be:

A sonar depth finder in a boat uses sound signals to determine the depth of water. Fourseconds after the sound leaves the boat it returns to the boat because of reflection fromthe bottom. Assume the speed of sound in water is 1,460 meters per second. The depth of the water is, in meters, :
An electron and a proton are accelerated through the same potential. If their masses are me and mp respectively, then the ratio of their de-Broglie wavelength is:
