Answer:
Density is defined as mass per unit volume. its SI unit is: kg/m³
Explanation:
Answer:
Power= 0.5hp = 375W
T = 3hrs = 10800s
Power = Work done/ Time
Work = Power * Time = 375 * 10800 = 4050000J
You are asked to give the answer in <span>g/cm3. So without knowing any single formulae you can just divide grams by cm3.

= 4.5 g/cm3
Answer:
Explanation:
Newton's first law of motion:
An object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.
Newton's second law:
The net force on an object is equal to its mass times its acceleration.
Newton's third law:
For every action, there is an opposite and equal reaction.
Gravitational potential energy i think
