Explanation:
<em>The height of the pendulum is measured from the lowest point it reaches (point 3). </em>
At 1, the kinetic energy of the pendulum is zero (because it is not moving), and it has maximum potential energy.
At 2, the pendulum has both kinetic and potential energy, and how much of each it has depends on its height—smaller the height greater the kinetic energy and lower the potential energy.
At 3, the height is zero; therefore, the pendulum has no potential energy, and has maximum kinetic energy.
At 4, the pendulum again gains potential energy as it climbs back up, Again how much of each forms of energy it has depends on its height.
At 5, the maximum height is reached again; therefore, the pendulum has maximum potential energy and no kinetic energy.
Hope this helps :)
I just did 1,000 nuclei divided by 250 and got 4.
The answer is 4 years.
Hope this helps!

D. The answer is D because any other scenario is possible. For example, in A, John could very easily put the planets in order. In problem B, he could draw some planets bigger than others. On C, he could color the planets on a different color. He can not hovever, move the planets
Answer:
920 kg
Explanation:
You can figure this out using the equation for kinetic energy:
Given:
KE = 222640
v = 22
m = ?
Answer:
The maximum allowed current for each speaker is 3.73 A
Explanation:
Given;
resistance of each speaker = 4.9Ω
power through each system channel = 68 W
the current through the fuse of the speaker circuit = 4 A
From ohms law, the maximum allowed current for each speaker is calculated as;'
P = I²R
Where;
p is power
I is current
R is resistance
I = √(P/R)
= √(68/4.9)
= 3.73 A
Therefore, the maximum allowed current for each speaker is 3.73 A
