Answer:</h2>
<h3>Interconversion of matter refers to change of one State to another. it is a process by which matter changes from one State to another and back to original state, without any change in it's chemical composition. Solid can be converted into liquids by heating</h3>

Ignoring air resistance . . .
After the bomb is released, tangential (horizontal) acceleration is zero,, normal (vertical) acceleration is 9.8 m/s^2 down (gravity).
An electron shell can hold 2(n^2) electrons (technically) where n is the shell number, i.e. shell 1 can hold 2, shell 2 can hold 8, 3 holds 18 and so on.
The atomic number of Nitrogen is 7, i.e. it has 7 electrons (to match its 7 protons, assuming it isn't an ion).
With the atomic number, you simply start from shell 1 and work out. So we put 2 electrons in shell 1, leaving us with 5 left. Shell 2 can hold 6 so we can fit all 5 in.
In other words, you should have 2 electron shells on the atom, shell 1 with 2 e- and shell 2 with 5 e-.
Answer:
B The force that the floor of the elevator exerts on you and the force that you exert on the floor of the elevator
Explanation:
A. is incorrect because the force of gravity on you will always stays the same while the force of the elevator exerts on you changes as it takes you upward
B. is correct in accordance to Newton's 3rd law of action and reaction forces.
C. is incorrect because gravity force stays the same while the force that you exerts on the floor change as elevator moving upward.
D. is incorrect although it states Newton's 1st law. However there can still be pair of forces (part B) that could counter balance each other among other forces.
