The spring of a rocket in flight burns up due to friction .At whose expense is the heat energy required for burning obtained ? The rocket or the atmosphere ?

Text Solution

Verified by Experts

Heat energy required for burning of casting of rocket comes from the rosket itself . As result of work done against friction the kinetic energy of rocket continuously decreases and this work against friction reappears as heat energy .

Answer the following : The casing of a rocket in flight burns up due to friction. At whose expense is the heat energy required for burning obtained ? The rocket or the atmosphere?

The helicopter has a mass m and maintains its height by imparting a downward momentum to a column of air defined by the slipstream boundary as shown in figure. The propeller blades can project a downward air speed v_0 , where the pressure in the stream below the blades is atmospheric and the radius of the circular cross section of the slipstream is r . Neglect any rotational energy of the air, the temperature rise due to air friction and any change in air density rho . If the power is doubled, the acceleration of the helicopter is :-

A rocket is fired ‘vertically’ from the surface of mars with a speed of 2 km s^(–1) . If 20% of its initial energy is lost due to martian atmospheric resistance, how far will the rocket go from the surface of mars before returning to it ? Mass of mars = 6.4 xx 10^(23) kg, radius of mars = 3395 km, G = 6.67 xx 10^(-11) N m^(2) Kg^(-2) .

A potato gun first a potato horizontally down a half-open cylinder of cross-sectional area A . When the gun is fired , the potato slug is at rest , the volume betweeen the end of the cylinder and the potato is V_(0) , and the pressure of the gas in this volume is P_(0) . The atmospheric pressure is P_("atm") . where P__(0) gt P_("atm") . The gas in the cylinder is diatomic, this means that C_(V) = (5R)/(2) and C_(P) = (7R)/(2) . The potato moves down the cylinder quickly enough that no heat is transferred to the gas. Friction between the potato and the barreel is negligible and no gas leaks around the potato . The parameters P_(0) , P_("atm"), V_(0) and A are fixed, but the overall length L of the barrel may be varied. The maximum kinetic energy E_("max") with which the potato can exit the barrel?

A rocket of mass 1000 kg is to be projected vertically upwards. The gases are exhausted vertically downwards with velocity 100m//s with respect to the rocket. (What is the minimum rate of burning fuel, so as to just lift the rocket upwards against the gravitational attraction?) (Take g=10m//s^(2) )

An ideal monoatomic gas is confined in a cylinder by a spring-loaded piston of cross-section 8.0xx10^-3m^2 . Initially the gas is at 300K and occupies a volume of 2.4xx10^-3m^3 and the spring is in its relaxed (unstretched, unompressed) state, fig. The gas is heated by a small electric heater until the piston moves out slowly by 0.1m. Calculate the final temperature of the gas and the heat supplied (in joules) by the heater. The force constant of the spring is 8000 N//m , atmospheric pressure is 1.0xx10^5 Nm^-2 . The cylinder and the piston are thermally insulated. The piston is massless and there is no friction between the piston and the cylinder. Neglect heat loss through lead wires of the heater. The heat capacity of the heater coil is negligible. Assume the spring to be massless.
