Q1 On an icy battle ground, a commando is getting ready to fire a cannon which includes a shell. The mass of cannon is 4 times as big as the mass of shell. As the commando has some knowledge of Physics, he calculates that to hit an enemy base (on ground], he has to launch the shell al en angle above the ground with a velocity w with respect to cannon. The range of the shell: 8w sin 20 5g w sin 20 5g 4w sin 20 5g 3w- sin 20 02 The equation of an ideal gas is given by. where is the volume of the gas and is nonzero constant. Then specific heat capacity of gas is. R C=C. (av-1) R C = C. c - 1 R C = C, + av R C =C+
