Physical change.
A snowflake is still considered water whether its liquid or solid.
You expend 1000 w of power moving a piano 10 meters in 5 seconds. how much force do you exert a. 50 n b. 50000 n c.250 n d. 500 n apex please
<em>P = W/t = (Fxd)/t and rearranging and solving for F, F = (Pxt) / d = (1000x5)/10 = 500 N, choice C.</em>
The band of stability curves upward at high atomic numbers due to the fact that excess of neutrons are required due to the repulsion between protons.
Atomic number is the number of protons. As the number of protons (atomic number) increase, the electrical repulsion force, due to the same sign of the protons inside the nucleus, becomes more dominant compared to the nuclear force attractions, then the nucleus needs more neutrons to gain stability.The presence of more neutrons decrease the density of protons which decreases the repulsion among them.
