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.
Are there answers choice or a picture I can see?
Answer:
(2)


Explanation:
<u>a)Kinematics equation for the first ball:</u>


initial position is the building height
The ball reaches the ground, y=0, at t=t1:

(1)
Kinematics equation for the second ball:


initial position is the building height
the ball is dropped
The ball reaches the ground, y=0, at t=t2:

(2)
the second ball is dropped a time of 1.03s later than the first ball:
t2=t1-1.03 (3)
We solve the equations (1) (2) (3):






vo=8.9m/s

t2=t1-1.03 (3)
t2=3.29sg
(2)
b)
t1 must : t1>1.03 and t1>0
limit case: t1>1.03:





limit case: t1>0:




Answer:
0.003
Explanation:
3 is in grammes so you divide by 1000
The answer would be 0.40m. you are finding how far the distance is between 10 and 50
