That's the chemical formula for the substance called "Calcium Nitride".
Answer:
The gravitational potential energy, P.E = 3345484.8 J
Explanation:
Given,
The mass of the person, m = 64 kg
The elevation of the village, h = 5334 m
The gravitational potential energy is the energy possessed by the body due to its height from the surface of the Earth at sea level.
Therefore, the gravitational P.E at height h above sea level is given by the relation
<em>P.E = mgh joules</em>
Substituting the given values,
P.E = 64 kg x 9.8 m/s² x 5334 m
= 3345484.8 J
Hence, the gravitational potential energy associated with the person, P.E = 3345484.8 J
Answer:
F = 592238.09 N
Explanation:
To find the mean force you first calculate the acceleration by using the following kinematic equation:
you do "a" the subject of the equation and replace the values of the other parameters:
next, the force, by using the second Newton law is:
hence, the force is 592238.09 N
- - - - - - - - - - - - - - - - - - - - - - - - - - -
