The answer for the following question is explained below.
- <u><em>Therefore the work done is 130 kilo Joules.</em></u>
Explanation:
Work:
A force causing the movement or displacement of an object.
Given:
mass of the person (m) = 65 kg
height of the cliff (h) = 2000 m
To calculate:
work done (W)
We know;
According to the formula:
<u>W = m × g × h</u>
Where;
m represents mass of the person
g represents the acceleration due to gravity
where the value of g is;
<u> g = 10 m/ s²</u>
h represents the height of the cliff
From the above formula;
W = 65 × 10 × 2000
W = 130,000 J
W = 130 Kilo Joules
<u><em>Therefore the work done is 130 kilo Joules.</em></u>
Answer:
Many things, such as building the Great Wall of China, and building highways.
Explanation:
Answer:
Spin a coil of wire inside a magnetic field or move a magnet inside a coil of wire.
Explanation:
This is according to Faraday's law of electromagnetic induction.
Answer:
False. They can’t change the charge but they can change the mass
On half life is 5370 years; 6 half lives have passed. You just multiply,
5370*6 = 32,220 years
