Answer:
B
Explanation:
This is a physics question, know that force is equals to mass divided by acceleration (acc.), so if the same force is applied, say 10 Newton and the mass of A is 2 and the mass of B is 4, then the acceleration of A is 0.2 and that of B is 0.4 by equating, and this applies to all cases.
Answer:
Water
Explanation:
Because it does not conduct much energy.
Answer:
It would be a physical change because you aren't changing to chemical properties of the glass, just the shape.
The ratio would be 1:1 or in other terms the number of protons are equal to the number of neutrons and vice-versa.
