Answer:
<h2>500 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
GPE = 5 × 10 × 10
We have the final answer as
<h3>500 J</h3>

C. Falling unstable air forms a cold airmass
The solution is impossible because when the apply the right equation for electrical power, the current obtained is 0.83 A and not 11.4 A
<h3>What is power?</h3>
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = voltage (V) × current (I)
P = IV
With above formula, we can obtain the current drawn by the bulb. Details below
<h3>How to determine the current flowing in the circuit</h3>
From the question given, the following data were obtained:
- Power (P) = 100 W
- Voltage (V) = 120 V
- Current (I) =?
P = IV
Divide both sides by V
I = P / V
I = 100 / 120
I = 0.83 A
Thus, we can see that the current drawn by the bulb is 0.83 A and not 11.4 A
From the above, we can see clearly why the inquisitive physics student' calculation is wrong.

Answer:
(e)-The current is doubled.
Explanation:
According to Ohm law, where I is the current, V is the voltage and R is the resistant.
If V is doubled, while R remains constant we would have
The current is doubled.
