Answer:
true
Explanation:
free fall is said to be the downward movement of an object under the force of gravity only
No, aluminum has a density near 2.7 g/cm^3
<span>7.8 g/cm^3 is near the density of iron (or in the case of a fork, steel).
this is it

Answer:

Explanation:
From the question we are told that:
Charges:



Distance 
Generally the equation for Force is mathematically given by

Therefore





Let me think about this........ correct me if I am wrong.......
Laws of thermodynamics
1) Energy cannot be created nor destroyed. It is transferred.
2) All spontaneous reactions will increased the entropy of the universe (More disorder)
3) The entropy of the crystal lattice structure at 0 K is zero
PE(coal) --> Steam(K.E) ................ This will increase entropy and also conversion of energy. So BOTH LAWS is my final answer.
Wait...... I would like to use a lifelines...... I want to phone my Physical chem professor.
*Ring Ring.........*
Me: Hello, I wanted to make sure if I got the correct answer.
Chem prof: You dont need my help, since you got the right answer.
Me: WOOT!!!!!!!
