Explanation:
Yes, it takes more energy to vaporize 1 kg of saturated liquid water at than it would at .
Answer:
0.125m
Explanation:
Given that:
Length of spring = 100m
Extension, e = 0.250
Recall :
F = ke - - - - (1)
Therefore, if spring is cut into 2 halves :
Then,
k = k1 + K2 ; since k1 and K2 are of equal length
Extension = e'
k = 2k
F = ke'
Then,
F = 2ke' - - - - - (2)
Equate (1) and (2)
ke = 2ke'
e = e'
0.250 = 2e'
0.250 / 2 = e'
e' = 0.125m
Answer:
<h2>2400 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = 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
PE = 60 × 10 × 4
We have the final answer as
<h3>2400 J</h3>
Hope this helps you
