Answer:
The two rays, CY and DM are diverging rays and when extended behind the mirror, they appear to intersect each other at point M'. Therefore, the properties of the images formed here are formed behind the mirror, between the pole and principal focus (f), the images are diminished and are virtual and erect.
Explanation:
<h2>Spherical Mirrors</h2>
- There are two kinds of spherical mirrors, concave and convex.
- The focal point (F) of a concave mirror is the point at which a parallel beam of light is "focussed" after reflection in the mirror. ...
- The focal length (f) and radius of curvature (R) are defined in the diagram at the right.

Answer:
c.) 36E
Explanation:
The magnitude of the electric field is given by the expression
(1)
where k is the Coulomb's constant, q is the charge that generates the field, and d is the distance from the charge.
In this problem, we have that the magnitude of the field at a distance d is 4E, so we can rewrite the previous equation as
Now we want to determine the electric field at a distance of 
away. Substituting into (1), we find
(2)
We also know that
(3)
So combining (2) with (3), we find a relationship between the original field and the new field:
Answer:
Conditions under which the belt and pulleys are operating – The friction between the belt and pulley may decrease substantially if the belt happens to be muddy or wet, as it may act as a lubricant between the surfaces.

Answer: 25 kg
Identify the given information.
f = 250 N
a = 10 m/s^2
Choose which formula you should use. In this case, you are finding the mass.
The formula for force is f = ma, so, using this, it is easy to find the mass.
f = ma Divide by a for both sides
m = f/a Formula for mass!
The formula for mass is m = f/a, where f is force and a is acceleration.
Substitute.
m = (250 N)/(10 m/s^2)
m = 25 kg
