Answer:
a)COP = 1.67
b) W = 300 J
Explanation:
given,
refrigerator removes = 500 J from a cold reservoir
discharge = 800 J to its hot reservoir
a) COP = 
COP = 
COP = 1.67
b) heat per cycle exhausted to the
W + 500 = 800
W = 800- 500
W = 300 J

Explanation:
it's needed top release energy due to the breaking of chemical bonds.
The displacement of the particle in the time interval 5 seconds to 8 seconds will be 1.5 meters.
Displacement is a vector quantity; meaning it has both magnitude and direction; magnitude being the distance between the interval at 5 seconds and position at 8 seconds, while the direction is from position at 5 second to position at 8 second. This is irrespective of the route followed during the time interval.
