A is not the correct answer because the amplitude and oscillation and there is 1/2 A in oscillation
In order to indicate that ones business is indeed

</span><span>Evaluation
– assess the plan after its pilot test for area of improvement</span>
PEg = Mass x Height x Gravity. So it doesn't matter how much PEg she started with, since you're finding how much it changed when she walked down 2.5 meters of stairs. So by plugging into the equation, you'll find how much potential energy was lost by walking down. (I'll leave it up to you since idk if you use 10 or 9.8 as gravity)

Answer:</h2>
If you triple the charge, the electric potential is 3V.
<h2>
Explanation:</h2>
If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.
<em>But why this is true?</em>
Well, the potential V due to a single point charge q is:

If the strength of the charge is tripled means that our new q1=3q, therefore:


So you can see that in fact if you triple the charge, the electric potential is 3V.
Answer:
Explanation:
given
m= 17.5kg
F= 75N
d= 5.7m
∪=0.150
θ= 21°
a. W = Fcos θ × d
75cos21° ×5.7
=399.106J
b. normal force is zero. 0 Joules
cos 90°=0
