Answer:
0.035 (3.5 %)
Explanation:
The thermodynamic efficiency is given by:
where
is the cold temperature
is the hot temperature
In this problem we have
So the efficiency is
Relativistic mean its so fast its a fraction of the sped of light.
Answer:
Explanation:
A body under concurrent forces (concurrent forces are forces with their line of action acting at a point) is said to be in equilibrium if the sum total of the forces acting on the body is zero.
For forces acting on a balance, the sum of upward forces and the downward forced acting on the balance must be equal for the balance to be in equilibrium.
Also the sum of clockwise moment must be equal to the sum of anticlockwise moment acting on the balance.
Moment is the product of force and the perpendicular distance from the force to the pivot.
