Answer: Pascal’s principle (apex)
Hope this helps you out!
When light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
To find the answer, we have to know about the rules followed by drawing ray-diagram.
<h3>What are the rules obeyed by light rays?</h3>
- If the incident ray is parallel to the principal axis, the refracted ray will pass through the opposite side's focus.
- The refracted ray becomes parallel to the major axis if the incident ray passes through the focus.
- The refracted ray follows the same path if the incident light passes through the center of the curve.
Thus, we can conclude that, when light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.

There's no physics or electronics to this question.
It's just arithmetic.
The last part of the question TELLS you how many 'coulombs per electron'.
If you just flip that fraction (divide ' 1 ' by it, take its reciprocal), then
you'll have 'electrons per coulomb', and 5 of those will answer the question.

Answer:
8 Newton
Explanation:
Weight = force
then, given,
weight= 0.495 kg
force= 7.28 N
Now,
the total force acting on the bird = (Weight + force)N
=(0.495 + 7.28)N
=8N
hence, the total force acting on the bird is 8 N.
