Answer:
The efficiency of the screw is 85.5%
Explanation:
to calculate efficiency you have to do
efficiency=energy output/ energy input × 100%
so e=855/1000 × 100%=85.5%
Well Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat. While <span>Heat energy (or thermal energy or simply heat) is defined as a form of energy which transfers among particles in a substance (or system) by means of kinetic energy of those particles. In other words, under kinetic theory, the heat is transferred by particles bouncing into each other.</span>
Newton’s Second Law concerns the generation of force based on an object’s mass and acceleration, as described by the equation F=ma.
