Many fundamental laws of physics and chemistry can be formulated when doing this.
Answer:
141.56 N.
Explanation:
Data given:
Weight of the box= 200.2 N
Angle with the horizontal= 37.1°
Solution;
Gravitational force on the box, 
= weight of the box
= 200.2 N
Component of gravitational force along plane = 
( ∅ )
= W * (sin∅)
= (200.1) * sin (37.1°)
= 141.56 N
A heat engine would be less efficient due to many factors
For instance, a heat engine is more efficient when it uses in cold weather because there is a greater temperature difference ( Carnot Efficient )
A heat engine could be less efficient because of friction
