Given: Mass m = 400 Kg; Height h = 3 m; g = 10 m/s²
Required: Work = ?
Formula: Work = Force x distance F = ma a = g F = mg
W = fd
W = mgh
W = (400 Kg)(10 m/s²)( 3 m)
W = 12,000 Kg.m²/s²
W = 12,000 J
It says on a website that humidity can be measured by human hair.
Total work done is 0.13 Joules
<h3>What is work done ?</h3>
The sum of the displacement and the component of the applied force of the object in the displacement direction is the work done by a force.
According to the given information
We need to find the work done
work done = force × distance
We are given,
force = 26 N
Distance = 0.0005 meter
hence ,
Work done = 26 × 0.005
= 0.13 Joules
Total work done is 0.13 Joules

Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
