It makes the data thet they collect more reliable so if they need the data again, they have already tested it a few times so therefor they know that it is right.
Answer:
Ep = 117600 J
Explanation:
Data:
- Mass (m) = 600 kg
- Height (h) = 20 m
- Gravity (g) = 9.8 m/s²
- Potential Energy (Ep) = ?
Use formula:
Replace:
- Ep = 600 kg * 9.8 m/s² * 20 m
Multiply operations, and units:
What is the potential energy?
The potential energy is <u>117600 Joules.</u>
Atoms of the same element having equal numbers of protons, but different numbers of neutrons is called isotope.
