The amount of potential energy of a 5.0-kilogram book that is moved to three different shelves on a bookcase would be 49 Joules ,73.5 Joules, and 98 Joules respectively.
Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.
Similarly, the total potential energy of the crane lift would be
PE = m*g*h
The potential energy of the book at 1.0 m is (5x9.8x1)= 49 Joules
The potential energy of the book at 1.5 m is (5x9.8x1.5) =73.5 Joules
The potential energy of the book at 2.0 m is (5x9.8x2)=98 Joules
Thus, the amount of potential energy of a 5.0-kilogram book that is moved to three different shelves on a bookcase would be 49 Joules,73.5 Joules, and 98 Joules respectively.

Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
hope it helps:)
Answer:
Then number of electrons is equal to number of protons
Explanation:
Since protons are positive and electrons are negitive, they cancel each other.
HENCE THEY ARE NEUTRL
