A car accelerates from rest. It reaches a velocity of 25m/s in 10 seconds. What was the cars acceleration

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.

What is the temperature in degrees celsius of a substance with a tempature of 49k

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
