In an electrolysis experiment, a cathode of mass 5g is found to weigh 5.0lg after a current
of 5A
flows for 50seconds
What is the electrochemical equivalent of the deposited
substance​

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
