Answer:
microwave, visible light, and radio waves.
Explanation:
Answer:
Part a)

Part b)

Part c)

Part 4)
angular acceleration will be ZERO
Part 5)

Explanation:
Part a)
Moment of inertia of the system about left end of the rod is given as

So we have





Part b)
If force is applied to the mid point of the rod
so the torque on the rod is given as




now angular acceleration is given as



Part c)
position of center of mass of rod and sphere is given from the center of the sphere as


so moment of inertia about this position is given as

so we have




Part 4)
If force is applied parallel to the length of rod
then we have


so angular acceleration will be ZERO
Part 5)
moment of inertia about right edge of the sphere is given as

so we have




Answer:
D. The sum total of all matter and energy
Explanation:
The universe is defined as a closed system that contains all forms of energy and matter. Therefore, includes the so-called dark matter and dark energy, which make up most of the universe, since ordinary matter would only represent just over 5% of the total.
Answer:
B. Medium
Explanation:
I don't know how to explain it but I already did this lesson in school
Escape velocity is the velocity an object needs to escape the gravitational influence of a body if it is in free fall, i.e. no force other than gravity acts on it. Your rocket is not in free fall since it is using its thruster to maintain a constant velocity so the notion of "escape velocity" does not apply to it.
