R=U/I so
U=RxI
U= 10 x 42
U= 420 volts
Coals energy is affordable and it is easy to burn.
Answer:
Explanation:
Potential energy, which is the energy a body assumes at a position, can be calculated using the formula:
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (m)
