Cells are the basic building block that makes up all living things. Cells are microscopic. What does this mean?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Me with this and you will be marked brainliest

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).
