Work Done = force • distance
Work Done = 5m • 50N
Work Done = 250J
Answer: 250 Joules
Answer:
A stream erodes the outsiders of meanders and deposits sand and gravel on the inside bends to from point bars. Both the velocity and channel depths are greatest near the outside bend and stream erode at outsides banks. In the same time sediment erodes is deposited in the slower water on the inside of the meander forming a point bar. Because the outside bank of a meander is eroded and sediment is deposited on the insde of the bend towards its outside bank. Hence in this meandering streams form an alternating series of cut banks and point bars along there course.
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 chemical reaction is written as follows:
Thus, the balanced chemical equation with their state is written as above.
Maybe because they’re friends and the stuff she put in there will become clear again, leaving the water clear and the friend without any suspicions?
