Physics question

An anti-whaling boat, the BlueYonder, is travelling in perfectly calm seas at a speed (relative to the surrounding sea) of 40 km h−1 on a bearing of 160◦. It is aiming to cross the path of a whaling ship, the Narwhal, which is sailing in perfectly calm seas at a speed...

Physics question

VA = VD, VB = VC. Curves AB and CD are isotherms; AD and BC are isochores. An ideal heat engine uses 0.03 mole of an ideal gas and operates between a hot reservoir at TH = 500 K and cold reservoir at TL = 320 K, in a cycle from A → B → C → D → A. From A → B the gas...
