[3 points] Question: Consider a pendulum made from a uniform, solid rod of mass M and length L attached to a hoop of mass M and radius R. Find the moment of inertia I of the pendulum about the pivot depicted at the left end of the solid rod.

I=

Explanation:

We are given that

Mass of rod=M

Length of rod=L

Mass of hoop=M

Radius of hoop=R

We have to find the moment of inertia I of the pendulum about pivot depicted at the left end of the slid rod.

Moment of inertia of rod about center of mass=

Moment of inertia of hoop about center of mass=

Moment of inertia of the pendulum about the pivot left end,I=

Moment of inertia of the pendulum about the pivot left end,I=

Moment of inertia of the pendulum about the pivot left end,I=

Moment of inertia  of the pendulum about the pivot left end,I=

Moment of inertia of the pendulum about the pivot left end,I=

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.

like poles repel so keep pushing north to north and repels funny to see this
