Answer:
Your answer is: K.E = 8.3 J
Explanation:
If the height (h) = 169.2 meters (m) and the mass (m) is 0.005 kilograms (kg) the total energy will be kinetic energy which is equal to the potential energy.
K.E = P.E and also P.E equals to mgh
Then you substitute all the parameters into the formula ↓
P.E = 0.005 × 9.81 × 169.2
P.E = 8.2908 J
So your answer is 8.2908 but if you round it is K.E = 8.3

<h2>Hello!</h2>
The answer is: A. Uranium is a rare metal
<h2>Why?</h2>
Since nuclear energy itself isn't non-renewable, the metal used to create it is non-renewable. Uranium (U-235) is a very rare metal that can not be reused after the nuclear energy process.
According to scientific reports, there is enough Uranium (U-235) to produce nuclear energy for about 5,700 years, using conventional nuclear energy plants.
Have a nice day!
there is 1000 grams in 1 kilogram
Divide
80/1000 = 0.08
0.08 kilograms is your answer
hope this helps
