A heat pump has a coefficient of performance of 7.05. If the heat pump absorbs 20 cal of heat from the cold outdoors in each cycle, find the heat expelled to the warm indoors. Answer in units of cal. I believe COP (heating mode) : 7.05 and COP = Qh/W Qc = 20 cal so I have to find Qh= ? cal I dont know an equation to put all this together? Please help, thank you.
The required force to push the box straight up at a constant speed is zero.
<h3>Net force on the box at constant speed</h3>
The net force on the box is calculated by applying Newton's second law of motion as follows;
∑F = 0
F - Ff = ma
<em>(at constant speed, acceleration is zero)</em>
Thus, the required force to push the box straight up at a constant speed is zero.
