Answer:
33,333.3J/s
Explanation:
Energy expended which is the work done in Joule
=250,000J
Time taken to expend the energy =7.5s
Power =Unknown
Formula
Power = <u> </u><u> </u><u> </u><u> </u><u> </u><u>Work</u><u> </u><u> </u><u> </u>
Time
Hence, Power = <u>250,000J</u>
7.5s
Power = 33,333.3J/s
A dishwasher and a dryer im not sure if that is right but that’s what I would put
Okay. There is a simple formula to go with this where:
p = mv
P: Momentum.
M: Mass.
V: Velocity
Sub the numbers in and solve for M.
10.0 = m(1.5)
10.0/1.5 = m
6.67 kg = m
Therefore the mass of the ball is 6.67kg.
Well first of all, a planet doesn't have a semimajor axis, although it's orbit does.
In an orbit with a smaller semimajor axis, the planet moves faster, and its orbital period is shorter.
That's why the International Space Station circles the Earth in less time than the Moon does.
