A man weighing 48 newtons climbs a 2.0-meter ladder. How much work is done? 0.0 J 24 J 96 J 124 J
2 answers:
<u>Answer:</u> Work done by the man will be 96 J.
<u>Explanation:</u>
Work is defined as the amount of energy that is transferred in order to move an object by an external force. It is expressed in joules.
Mathematically,
Where,
W = Work done = ? J
F = Force applied = 48 N
d = Displacement of the body = 2 m
Putting values in above equation, we get:
Hence, work done by the man will be 96 J.

Answer : The Lewis-dot structure of is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that carbon has '4' valence electrons, chlorine has '7' valence electron and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in = 1(4) + 2(7) + 1(6) = 24
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
