Answer:
The answer is
Step-by-step explanation:
Probability=number of specific outcomes / total possible outcomes
P(g)=12/(12+8)
P(g)=12/20
P(g)=3/5
Answer:
The energy in object is 3.8 Kilo Joules.
Step-by-step explanation:
We are given the following in the question:
Mass = 20 kg
Height,h = 20 m
g=9.5 m/s^2
Formula:
Potential energy =

Putting value we get,

Thus, the energy in object is 3.8 Kilo Joules.
