Asprinter accelerates from rest to a velocity of 12m/s in the first 6 seconds of the 100 meter dash .
a ) how far does the sprinter travel during the first 6 seconds ?
b ) how much farther does the sprinter have to travel to reach the finish line ?

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

Explain why electric current cannot exist if a current doesn't have a voltage source.

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
