One mole of a monatomic ideal gas has an initial pressure, volume, and temperature of Po, Vo, and 335 K, respectively. It undergoes an isothermal expansion that triples the volume of the gas. Then, the gas undergoes an isobaric compression back to its original volume. Finally, the gas undergoes an isochoric increase in pressure, so that the final pressure, volume, and temperature are Po, Vo, and 335 K, respectively. Find the total heat (including the algebraic sign) for this three-step process.
A car is driven east for a distance of 47 km, then north for 25 km, and then in a direction 29° east of north for 29 km. find (a) magnitude (in km) of car's total displacement from its starting point and (b) the angle (from east) of the car's total..
