Since the angular distributions of the absorbed and emitted
radiation patterns are different and also the EM radiation carry
momentum,so it is found that a net radiation pressure force is
exerted more on smaller grain.When calculated over much long period
of time,this force comes out to be very small.
This result reflects that putting the net radiation pressure can
significantly modify the grain orbit and hence it causes the grain
to move in spiral path toward the Sun.

Constants In this example we will investigate the viability of using radiation pressure to propel a spacecraft. Suppose a spacecraft with a mass of 2.50 x 10 kg has a solar sail made of perfectly reflective aluminized film with an area of 2.59 x 106 m2 (about 1 square mile). If the spacecraft is launched into earth orbit and then deploys its sail at right angles to the sunlight, what is the acceleration due to sunlight? (At the earth's distance...

6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...
