ROCKET PROPULSION:
The motion of a rocket is an application of the law of conservation of momentum and Newton's 3rd law of motion. The gases ejected out from the combustion chamber of the rocket, move downward and gain a downward momentum and the rocket moves upward to balance the momentum of gases.
An α particle is a positively charged particle. Rutherford observed the behaviour of these particles when they approach the interior of the atoms as shown in fig. Rutherford ob
An air stream is saturated with a vapor (B) at 130°F and 1 atm pressure. It is cooled down to 80°F where some of the B is condensed and separated from the vapor stream. The remai
The mass of a proton and of an antiproton is 1.00728 u. Recall that the conversion of exactly 1 u into energy yields 931.5 MeV. a. Measure the mass used up when a proton and
