I don't see any answers, but I do know that machines help for example: make chocolate bars. people do not have to cut the bars or another example: salt or season chips. or washing laundry. or electric cutters help so we do not have to do it by hand or with a knife.
Does this Help?
A or c I’m pretty sure it’s c though hope it helps:)
The answer is B. 79 joules.
To calculate this we will use the formula for potential energy (PE):
PE = m * g * h
where m is mass of an object, g is gravitational acceleration, h is a height at which is the object.
It s given:
m = 8.10 kg
g = 9.8 m/s²
h = 0.99 m
After replacing them in the formula for potential energy:
PE = 8.10 * 9.8 * 0.99 = 78.6 J ≈ 79 J
