Answer: The number of people that work in the white house are 200. If that is your question? If not just let me know and i will gladly help.
the orbit of the moon around earth causes the phases since the light from the moon is caused by a reflection of sunlight... btw wrong subject,....
<em>1</em><em>.</em><em>259ms^2</em>
Explanation:
since, WORK DONE = FORCE*DISTANCE
AND, FORCE=MASS*ACCELERATION
SO, THE WORK DONE BECOMES=MASS*ACCELERATION*DISTANCE
ACCELERATION=WORK/(MASS*DISTANCE)
AND, WORK=686J
MASS=227kg
DISTANCE=2.4m
THEREFORE, ACCELERATION=686/(227*2.4)
=686/544.8
=1.259ms^2
Explanation:
Remember that power is defined as how much Work is done per unit of time.

Work is defined as the amount of force applied across a certain distance.

Since in both cases of climbing the ladder (on Earth and the moon), Luke coveres the same amount of <em>distance </em>in the same amount of <em>time</em>, we are only left with one difference between the two cases - gravity.
If you were to carry your backpack on the moon with the same load of text books, it would take less force to pick it up on the moon. Therefore, Luke expends less effort on the environment with less gravity - the moon.
To find the difference factor - you would want to divid the gravitational contants between earth and the moon.
Answer:
.05
Explanation:
wavelength/frequency = wave speed
45 = 2.5/x
x = 0.05
