<h3><u>Answer;</u></h3>
A. Skeletal muscles, which are made of fibers, nerves, and blood vessels, contract in order to make the body move.
<h3><u>Explanation</u>;</h3>
- <em><u>Muscular tissues functions in movement and locomotion through its direct connection with the skeletal system. </u></em>
- <em><u>Skeletal muscles are responsible for moving the body. The skeletal muscle contractions pull on tendons, which as attached to bones. When the skeletal muscle contraction causes the muscle to shorten, the bone and thus the body par will move. </u></em>
- <em><u>Skeletal muscles also provide structural support for the entire body. </u></em>
Answer:
262.5 Nm
Explanation:
Torque is the rate of change of angular momentum.
Hence, we have

Δ<em>L</em> is the change in angular momentum.
Using values in the question,

What we call a "year" is the time a body takes to complete one orbital revolution
in its path around the sun. The way gravity works, the farther a planet is from the
sun, the slower it moves, and the longer it takes to complete that trip. So, farther
out from the sun means a longer "year".
Everybody knows that if you want to get more warmth, then you have to stand closer
to the fire, and it's the same with planets. The farther a planet is from the sun, the less
heat it gets from the sun, and in most cases, that means its average temperature is
lower. (The planet's average temperature is affected by other things besides its distance
from the sun, such as how much heat comes up from inside, and how much heat its
atmosphere traps.)
The farther a planet's rotation axis is tilted from being perpendicular to the plane
of its orbit, the more seasonal variation there can be in the temperature at any one
place on its surface. Of course, this is kind of irrelevant if the planet has no surface.
B) no light pass through
Explanation:
An opaque material is a material that does not allow light to pass through. Opaque materials are the most common materials, they do not allow light to pass through.
- All opaque materials will cast shadows along their path when there is a screen.
- Transparent materials allows light to pass through for example glasses.
- Translucent materials allows light to go through partially.

Answer:

Explanation:
Given:
wavelength used by the first microscope, 
resolving power of the first microscope, 
wavelength used by the second microscope, 
For the microscopes the resolving power is given as:

where:
wavelength of the laser source used
numerical aperture of the microscope
smallest feature that can be distinguished using the optical device
For the first microscope:



Since both the optical device are identically built we will have:

Now for the second optical device:
