Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
Explanation:
You are not raising the temperature of the block of ice. You are making it turn phase.
H = m * hf
That's the mass of the block and the latent heat of fusion.
D.
In an atom of hydrogen the orbit radius is given by the formula:
r = n² · α₀
where:
n = number of orbit = 15
α₀ = Bohr radius (innermost radius) = 0.529 Â
Since d = 2 · r, we can write:
d = n² · d₀
= 15² · 1.06
= 238.5 Â
Hence, the <span>diameter of the fifteenth orbit of the hydrogen atom is 238.5 </span>Â.
