Define Rocket in Drag (Princeton)?
A rocket has an effectual frontal area A and blasts off with a constant acceleration a straight up from the surface of the Earth.
a) Use either/or dimensional analysis or an elementary derivation to find out how the atmospheric drag on the rocket should vary as some power(s) of the area A, the rocket velocity v and the atmospheric density p assuming that we are in the region of high Reynolds numbers.
b) Presume that the atmosphere is isothermal with temperature T. Analyzes the variation of the atmospheric density p with height z. Presume that the gravitational acceleration g is a constant and that the density at sea level is Po.
c) Find the height ho at which the drag on the rocket is at an utmost.
A lift is moving down with an acceleration of 3m/s. A ball is released 1.7m above the lift floor. How long will the ball take to hit the floor?
A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V. The secondary winding gives a full load current of 30A at a power factor of 0.8 l
in some case we take y=-g but in some case we take y=g... why???
The conductive method Heat can be transferred by conduction from warmer to cooler objects, the quantity of heat transfer depends on the temperature difference between the two
