You are trying to lift a car to change a tire using a hydraulic jack. You apply a force of 57 N to the input piston who's diameter is d1. As a result, the output piston, which has a diameter d2, applies a force to the car. The ratio d2/d1 has a value of 7.5. Ignore the height difference between the input piston and output piston and determine the force that the output piston applies to the car.

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics

The particles that are found in the nucleus of an atom are

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).
