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:
Volume of metal cylinder with the help of a vernier callipers of least count 0.01 cm when diameter is 1.22 cm and length 5.35 cm. Find its uncertainty as
A two-slit arrangement is set up to produce an interference pattern on a screen. The fringes are too close together for convenient observation. How could the distance between them be increased?
In a spectrometer experiment monochromatic light is incident normally on a diffraction grating having 4.5 x 105 lines per meter.The second order line is seen at an angle of 30 to the normal what is the wavelength of the light?
The value of acceleration due to gravity on the surface of the earth is g.If the diameter of the earth becomes double of its present value and its mass remains unchanged, the value of acceleration due to gravity on the surface of the earth would become
If the acceleration due to gravity at the earth's surface is 9.8 m/s2 and the mass of the earth is 80 times that of moon and radius of earth 4 times that of moon,the value of G at the moos's surface will be:
A body of mass 5 kg is moving with a momentum of 10 kg m/s.A force of 0.2 N acts on it in the direction of motion of the body for 10 seconds.The increase in its kinetic energy is
Two point charges A and B separated by a distance R attract each other with a force of 12 x 10-3 N.The force between A and B when the charges on them are doubled and distance is halved
