Otal energy= PEmax on the spring = KEmax of the oject
<span>Total Energy= KE+PE at v or x not maximum. </span>
<span>Using the second line </span>
<span>E= 3/4 E + PE </span>
<span>PE = 1/4 E </span>
<span>PEmax =E = 1/2 kA^2 </span>
<span>PE=E/4 = (1/2)kA^2 / 4= kA^2/8

Answer:
1.08×10⁹ J
Explanation:
From the question given above, the following data were obtained:
Power (P) = 100 kilowatt
Time (t) = 3 hours
Energy (E) =?
Next, we shall convert 100 kilowatt to Watts. This can be obtained as follow:
1 KW = 1000 W
Therefore,
100 KW = 100 KW × 1000 W / 1 KW
100 KW = 100000 W
Thus, 100 KW is equivalent to 100000 W.
Next, we shall convert 3 hrs to second (s). This can be obtained as follow:
1 h = 3600 s
Therefore,
3 h = 3 h × 3600 s / 1 h
3 h = 10800 s
Thus, 3 h is equivalent to 10800 s.
Finally, we shall determine the amount of energy consumed as follow:
Power (P) = 100000 W
Time (t) = 10800 s
Energy (E) =?
P = E/t
100000 = E / 10800
Cross multiply
E = 100000 × 10800
E = 1.08×10⁹ J
Therefore, 1.08×10⁹ J of energy was consumed.
That is 19 seconds cuz of the fast inplosion

The sign of the charged particle is positively charged.
<h3>What is potential difference?</h3>
- When a single charge is transported in an electric field, work is done by the potential difference (also known as electrical potential).
- There is potential energy stored in this charge that could flow when work is done on it.
- Voltage is the possibility of a single charge flowing. The need to flow increases with voltage.
- Here, voltage can be the potential differences.
The potential difference between the 2 points determines the movement of that particle. An electron moves from lower to higher potential which is negatively charged, and a positively charged particle moves from higher to lower potential.
Now, since the particle is moving from a point A having 160 v potential to point B having 100 v potential that is it is moving from higher potential to a lower potential therefore the particle will be a positively charged one.
