Answer:
<h2>Rotational inertia first decreases and then increases as the satellite is ready to land</h2>
Explanation:
This problem is based on the conservation of angular momentum.
<h2>What is the Law of Conservation of Angular Momentum
?</h2>
The Law of Conservation of Angular Momentum states that
<em>"The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point".</em>
The rate of rotation increases greatly when the Satelite is moved inwards by 10%, decreasing the moment of inertia. The work-done to pull in the Satelite results in an increase in rotational kinetic energy.
Answer: destructive interference
Explanation:
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
