A particle with a charge of +8.4 C and a speed of 40 m/s enters a uniform magnetic field whose 휇magnitude is 0.33 T. For each of the three cases in the drawing, calculate the magnitude and direction of the magnetic force on the particle.

Explanation:

Given that,

Charge of the particle, q = 8.4 C

Speed of the particle, v = 40 m/s

Magnitude of magnetic field, B = 0.33 T

Let us assumed to find the magnitude and direction of the magnetic force on the particle. Let 30.0 degrees for one, and 150 degrees for two, with a perpendicular charge. So,

If angle is 150 degrees

If angle is 90 degrees

Hence, this is the required solution.

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.
