We are given
the torque requirement of 97 Newton meter.
The formula of the torque is
τ = r * F * sinθ
where
τ is the torque
r = radius from the axis of rotation to the point of application.
F = force exerted
θ = the angle between the lever arm and the radius
Try to substitute the given and solve for F.
A. Energy was used to change phase of water from liquid to gas (evaporation). it is radiated back into the atmosphere from the stove.
This is because water evaperates after reaching it's boiling point.
