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>
Hope this helps you
Answer:
kinetic energy = 414 J
Explanation:
given data
mass = 23 kg
speed = 6 m/s
height = 17 m
to find out
kinetic energy
solution
we get kinetic energy that is express as
kinetic energy = 0.5 × m × v² ..........................1
here m is mass and v is speed so
put here value we get kinetic energy
kinetic energy = 0.5 × 23 × 6²
kinetic energy = 414 J
Answer:
0.96 kWh
Explanation:
First of all, we can find the power of the appliance using the formula:
where
V = 120 V is the voltage of the source
I = 2 A is the current
Substituting,
Now we want to find the amount of energy used by the applied in a time of
t = 4 h
The amount of energy is given by
where
P = 0.24 kW
t = 4 g
Substituting,
6A. bottom
6B. as distance between the charges increases the force weakens between them
