Ainsect is resting on the rim of a rotating table topper the topper is stopped after covering 125° and 1.3s later. what was the insect angular velocity in rad/s.
answer choices:
a. 0.7384
b. 1.6782
c. 2.1866
d. 464.73

Explanation:

I assume you're looking for the average angular velocity:

ω_avg = Δθ / Δt

ω_avg = (125° × π / 180°) / (1.3 s)

ω_avg = 1.6782 rad/s

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.

true tan speed = ang vel x radius
