Aperson looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 3.84 m/s relative to the ground. when the train moves at a constant velocity, the raindrops make an angle of 25° when they move past the window, as the drawing shows. how fast is the train moving?

Determine the maximum r-value of the polar equation r =3+3 cos 0

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).
