Explain the collector as the hot reservoir
The mean solar flux at the Earth's surface is ~2.00 J*cm^-2*min^-1. In a nonfocusing solar collector, the temperature can reach a value of 85.0 C. A heat engine is operated using the collector as the hot reservoir and a cold reservoir at 298 K.

If the vessel had a yield strength in compression in equal to that of 4340-HR steel (901 x 10^6Pa) and a safety factor of 2 was employed, what would the wall thickness need to be to withstand the pressure at the bottom of Challenger Deep (1086 atm

Radium (Ra) decays to radon (Rn) which decays to polonium. If at t = 0, a sample is pure radium, how much polonium does it contain at time t? Suppose No is the number of radium atoms at t = 0, and Lambda1 and Lambda2 are the decay constants for Ra
