consider two point charges of 1.60uC and -22.25uC. Determine the magnitude of the force between the two charges when placed 6.50cm apart.

Explanation:

From the question we are told that

Point charges

Displacement

Generally the equation for Coulomb's law is Mathematically given as

Therefore

with  -(negative) showing form of force Magnitude =>

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.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
