A 1.4 kg water balloon is swung in a vertical circle of radius 0.6m. The balloon rotates at a constant speed in a circle and takes 0.75s to complete one full rotation. a) What is the force of the rope on the water balloon at the top of the swing?
b) What is the force of the rope on the water balloon at the bottom of the swing?

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
