Answer:
900 m ( 0.9 km)
Explanation:
from the question we have the following
first person's height (h) = 100 m above the earths surface
distance to the horizon that can be seen (s) = 15 km = 15,000 m
second person's height (h1) = 36 m
distance to the horizon that can be seen (s1) = ?
take note that the distance (s) a person can see = square root of the person's height
s = 
x K
where k is a constant
from the height and the distance the first person can see we can get the value of K
15000 = 
x K
15000 = 10 x K
K = 150
now putting the value of K and the height of the second person into the equation we can get the distance into the horizon the person can see
s = 
x 150
s = 900 m
therefore the second person who is 36 m above the surface can see 900 m ( 0.9 km) into the horizon
I’m not sure if its correct but I think it’s focal Ray point
For concave mirrors, some generalizations can be made to simplify ray construction. They are: An incident ray traveling parallel to the principal axis will reflect and pass through the focal point. An incident ray traveling through the focal point will reflect and travel parallel to the principal axis.
Answer:Friction is a force that opposes the motion of objects; friction can cause objects to slow down. Air resistance is a type of friction. Air resistance causes moving objects to slow down. Different physical properties, such as the shape of an object, affect the air resistance on an object.

<u>Functions</u>
When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.
The area of a circle is computed by the well-known formula
We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in 
.
The required function is
For a radius of 4.3 cm:
