QAIPM-2011-Ph-1892: NEET 2011 Physics - Class 11 AIPM-2011-Ph-1892 Solution: During an isothermal expansion a confined ideal gas does -150 J …

During an isothermal expansion a confined ideal gas does -150 J of work against its surroundings. This implies that 150 J of heat has been removed from the gas 300 J of heat has been added to the gas no heat is transferred because the process is isothermal 150 J of heat has been added to the gas

Step-by-Step Verified Solution

By the theorem of parallel axes, the moment of inertia of a body about any axis is equal to the sum of the moment of inertia about a parallel axis through the centre of mass and Ma 2 , where M is the mass of the body and a is the separation between the two axes. Therefore, the moment of inertia of the rod about an axis passing through one of its ends and perpendicular to its length is I = I 0 + M (L/2) 2 = I 0 + ML 2 /4
