------------------------------------------------ How much potential energy is in a closed system where the height of the object is 2 m, and the mass is 10 kg?

Hint: [tex]PE = mgh[/tex]

A. 10 J
B. 196 J
C. 20 J
D. 200 J

Answer :

Answer:

D. 196 J

Explanation:

PE=mgh=10×9.8×2=196J

Answer:

Answer: B. 196 J

• potential energy is calculated from the formula:

[tex]{ \tt{p.e = mgh}}[/tex]

• m = 10 kg

• g = 9.81 m/s²

• h = 2m

→ Substitute:

[tex]{ \tt{p.e = (10) \times (2) \times (9.81)}} \\ \\ → \: { \boxed{ \tt{potential \: energy = 196.2 \: \: joules}}}[/tex]
