Answer:
Work done against gravity will be
W = Mgℓ
Explanation:
Work done to raise the mass from ground to given height is against gravity
So here work done is given by the formula
here we know that
it is the force due to gravity which is also known as weight
so here distance moved by the object is given as
d = ℓ
now work done is given as
W = Mg ℓ
Answer:
the atomic mass is 11
Explanation:
the atomic mass is basically how many protons and neutrons there are so for this all you have to do is some simple math:
5 + 6 = 11
and boom, ur atomic mass is equal to 11!
Answer:
The carriage has the energy, W = 2469.6 J
Explanation:
Given data,
The height of the hill, h = 21 m
The carriage with the baby weighs, m = 12 kg
The energy possessed by the body due to its position is the potential energy,
<em>W = P.E = mgh joules</em>
Substituting the values,
W = 12 x 9.8 x 21
= 2469.6 J
Hence, the carriage has the energy, W = 2469.6 J
