Answer:
Explanation:
We can use the equation of speed in terms of distance. We know that the speed of light is constant value so we will have:
Now we know that

By using concave lens, we can correct Myopia and Hyperopia can be corrected by convex lenses.
To find the answer, we need to know about Myopia and Hyperopia.
<h3>
What is Myopia and
Hyperopia?</h3>
- Myopia is an optical defect, in which a person can see nearby objects clearly and cannot see far off objects clearly.
- Here the eyeball becomes too longer, and the focal length of eye lens become too short.
- It can be corrected by using concave lens.
- For Hyperopia, the person can see far off objects clearly and cannot see nearby objects clearly.
- This can be corrected by using convex lens.
Thus, we can conclude that, by using concave lens, we can correct Myopia and Hyperopia can be corrected by convex lenses.

To solve this question, we need to use the component method and split our displacements into their x and y vectors. We will assign north and east as the positive directions.
The first movement of 25m west is already split. x = -25m, y = 0m.
The second movement of 45m [E60N] needs to be split using trig.
x = 45cos60 = 22.5m
y = 45sin60 = 39.0m
Then, we add the two x and two y displacements to get the total displacement in each direction.
x = -25m + 22.5m = -2.5m
y = 0m + 39.0m
We can use Pythagorean theorem to find the total displacement.
d² = x² + y²
d = √(-2.5² + 39²)
d = 39.08m
And then we can use tan to find the angle.
inversetan(y/x) = angle
inversetan(39/2.5) = 86.3
Therefore, the total displacement is 39.08m [W86.3N]
English please. I don’t under this. Is it Czechish Orr???
