Answer:
the answer to the question is a system of insulating element designed to control the path of electric current for a particular purpose
A heat pump is a device that is capable of transferring heat energy from a source of heat to what is known as the heat sink. It also moves thermal energy in the opposite direction of a spontaneous heat transfer through heat absorption from a cold space and releasing it to a warmer space.
When a heat pump is being utilized for heating, it employs the same principle with that of the refrigeration cycle used by an air conditioner or a refrigerator, but in the opposite direction since it releases heat into a conditioned space rather than the surrounding environment. Moreover, heat pump resembles much as refrigeration since it has the same components with the latter except for the presence of a reverse valve.
Answer:
923.44N
Explanation:
Obviously Fn cannot equal Fg since the elevator is moving up
Where Fn is the force read on the scale
Fg is gravitational force=mg=77.6 x 9.8=760.48N
So we use this equation:
Fnet = Fn - Fg
ma = Fn - mg
77.6 x 2.1 = Fn – 760.48
162.96N = Fn – 760.48N
923.44 N = Fn
The answer is 923.44 N
When the car comes to a stop, the final velocity must be 0 m/s.
Since the car js decelerating in a forward direction, acceleration must be negative.
final v = initial v + a•t
0 = 20 + (-6)t
t = 3.33s
