Answer:
80 times 12=960
Explanation:
You have to do the equation for work, the equation is work= force times distance, the force here is 80newtons, the distance is 12meters, so you would do 80 times 12 to get your answer of 960
The answer for this question is o power
Answer:light year is a measurement of distance. It is often used in special theory of relativity
Explanation:
Answer:
amount of work done = -1.77 J
Explanation:
given data
mass = 0.25 kg
speed = 5 m/s
height = 2m
to find out
amount of work done by the water on the ball bearing
solution
we get here potential energy when ball fall
potential energy = mgh
potential energy = 0.25 × 9.8 × 2
potential energy = 4.9 J
and that lose potential energy gain by kinetic energy that is express as
kinetic energy = 0.5 × m × v²
kinetic energy = 0.5 × 0.25 × 5²
kinetic energy = 3.13 J
so we get now work done that is
work done = kinetic energy - potential energy
work done = 3.13 J - 4.9 J
amount of work done = -1.77 J
