The coolant gas in a fridge takes heat from the fridge and "pumps" or "dumps" it in the outside. The back of a working fridge is usually quite warm, and one source of that heat is the contents of the fridge.
Electrical energy is used to pump the coolant round the various components of the fridge's cooling system. It also possibly powers any lights in the fridge. That funny whirring sound may well be a motor, and motors are driven by electrical energy. If your power goes off, then your fridge stops fridging. all the stuff in the fridge warms up to room temp slowly, and you may end up with some "too warm" grub.
Answer:
Weight of the object will be 195.6 N
Explanation:
We have given mass of the object m = 20 kg
And acceleration due to gravity at any location is given 
We have to find the weight of the object in N at the location where value of acceleration due to gravity is
Weight of the object is given by W = mg , here W is weight , m is mass and g is acceleration due to gravity
So weight W = 20×9.78 = 195.6 N
So weight of the object will be 195.6 N
Answer:
Explanation:
we can look for the final velocity of the object using the eqaution of motion as shown:
v² = u²+2gH
v is the final velocity
u is the initial velocity = 10m/s
g is the acceleration due to gravity = 9.81m/s²
H is the height of the object = 175m
Subxtitute the given parameters inti the formula and get v:
v² = 10²+2(9.81)(175)
v² = 100+3433.5
v² = 3533.5
v = √3533.5
v = 59.44m/s
Hence the final velocity of the object is 59.44m/s

Answer: 240.25joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
Thus, Workdone = Force x distance
Since, Work = ? (unknown value)
Force = 77.5N
Distance = 3.1metres
Workdone = 77.5 N x 3.1metres
= 240.25 joules
Thus, Amanda did a work of 240.25joules on the crate
