C. Elastic collision. A perfect elastic collision is on that doesn't result in any k.e loss during the collision.
Because cold air tends to more dense, and it's therefore heavier, and it sinks.
Hot air though is hot with no density so it's light and rises.
Answer:
Land and sea breezes are wind and weather phenomena associated. A land breeze is a breeze blowing from land out toward a body of water and a sea breeze is a wind blowing from water onto land. Land breezes and sea breezes arise because of differential heating between land and water surfaces. Land and sea breezes can extend inland. Land and sea breeze patterns can greatly influence fog distribution and pollution accumulation or dispersion over inland areas.
<span>Answer:
F=GMm/r^2 where G is the newtonian grav cst, M the mass of the star, m the mass of the planet, and r the planet-star distance
F1=GMm1/r1^2
F2=GMm2/r^2
F2/F1 = [GMm2/r2^2]/[GMm1/r1^2]
F2/F1=(m2/m1)(r1/r2)^2 = (2)(1/2)^2 = 1/2
because m2/m1=2 and r2/r1=2</span>
The induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux enclosed by the circuit. That is the textbook definition that is widely accepted.
