What is the potential energy of a falling rock if it has a mass of 64 kg and fell from a height of 54 m
1 answer:
<u>P.E (Potential Energy) = 33868.8 J</u>
<u>Explanation:</u>
The formula to calculate Potential energy is:
PE = mgh
where PE = potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object
Here, m = 64 kg
g = 9.8
h = 54 m
So, substituting the values in the formula:
PE = mgh
= 64 × 9.8 × 54
= <u> 33868.8 J</u>

Answer:
The value of the inductance is 1.364 mH.
Explanation:
Given;
amplitude current, I₀ = 200 mA = 0.2 A
amplitude voltage, V₀ = 2.4 V
frequency of the wave, f = 1400 Hz
The inductive reactance is calculated;
The inductive reactance is calculated as;
where;
L is the inductance
Therefore, the value of the inductance is 1.364 mH.
