5. a chandelier is hanging suspended by a chain from a ceiling. the mass of the chandelier is 9.4kg,
the mass of the chain is 0.37kg. what is the tension on the chain (in newtons)?

What are similarities and differences between refraction, reflection, diffraction and absorption?

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).

In which of these cases are the two wave points considered to be in phase with each other?
