Explain why changing the axis of rotation of an object changes its moment of inertia.
Yuri [45]

The mass distribution along a particular axis affects the moment of inertia.

<h3>What is the moment of inertia?</h3>

Each component of the object's mass is now located at a different distance from the axis than it was previously if the axis is altered. Axes perpendicular to the rod that first travel through its center of mass and then through one of its ends are used to compare the moments of inertia of uniformly stiff rods.

As an illustration, you can easily change the direction of rotation by repeatedly wriggling a meter stick along an axis that passes through its center of mass. You will have a harder time moving the stick back and forth if you shift the axis to the end. Because a major portion of the stick's mass is located farther from the axis, the moment of inertia around the end is much larger.

To learn more about moment of inertia, refer to:

The old-fashioned record player had two speeds: one for long-playing albums (LP) and one for singles. The turntable speed for LP
eimsori [14]

Answer:

\alpha = 0.305 rad/s^2

Explanation:

initial frequency of revolution is given as

f_1 = 100/3 rpm

now initial angular speed is

\omega_i = 2\pi f

\omega_i = 2\pi(\frac{100}{3\times 60})

\omega_i = 3.49 rad/s

Similarly final angular speed is given as

\omega_f = 2\pi f_2

\omega_f = 2\pi(\frac{45}{60})

\omega_f = 4.71 rad/s

Now angular acceleration is given as

\alpha = \frac{\omega_f - \omega_i}{\Delta t}

\alpha = \frac{4.71 - 3.49}{4}

\alpha = 0.305 rad/s^2

Saturn orbits the Sun at a radius of about 1.4×109 km. At this distance the force of gravity on Saturn due to the Sun is 3.7×102
Afina-wow [57]

Explanation:Saturn is the second largest planet of the solar system in mass and size and the sixth nearest planet in distance to the Sun.

In the night sky Saturn is easily visible to the unaided eye as a non twinkling point of light.
