Because the molecules slow down and get closer together in the space that they are in. Once they get to freezing point, the molecules almost stop moving altogether.<span />
Answer:
mass of one atom is measured in the unit of 1 amu
Explanation:
As we know that the mass of one atom is very small and it is of order of 
here we know that 1 amu is defined as 1/12 part of mass of 1 atom of C-12 isotope
so here we will have
so here we can say that mass of one atom is measured in the unit of 1 amu
Well, the answer to this question is D) 10 m/s^2 in the direction of the meteoroids motion.
Glad I could help and have a fantastic day!
Also, can you please mark my answer as the brainliest answer?
Thanks.
Answer:
B. 2nmv
Explanation:
Pressure is force over area.
P = F / A
Force is mass times acceleration.
F = ma
Acceleration is change in velocity over change in time.
a = Δv / Δt
Therefore:
F = m Δv / Δt
P = m Δv / (A Δt)
The total mass is nm.
The change in velocity is Δv = v − (-v) = 2v.
A = 1 and Δt = 1.
Plugging in:
P = (nm) (2v) / (1 × 1)
P = 2nmv
