of the eye and the eye is 0.800 × 10^3 mm from the mirror, how far is the image
from the mirror? What is the size of the image? Is the image real or virtual?
Answers
Answer:
q = 224 mm, h ’= - 98 mm, real imagen
Explanation:
For this exercise let's use the constructor equation
where f is the focal length, p and q are the distance to the object and the image respectively.
In a mirror the focal length is
f = R / 2
indicate us radius of curvature is equal to the diameter of the eye
R = 3,50 10² mm
f = 3.50 10² /2 = 1.75 10² mm
they also say that the distance to the object is p = 0.800 10³ mm
1 / q = 1 / f - 1 / p
1 / q = 1 / 175 - 1 /800
1 / q = 0.004464
q = 224 mm
to calculate the size let's use the magnification ratio
m =
h '=
h ’= - 224 350 / 800
h ’= - 98 mm
in concave mirrors the image is real.

Answer:
The question seems to refer to Newton's Laws of Motion. Here are examples of the 1st, 2nd, and 3rd laws:
1st Law (Law of Inertia):
- An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction unless acted upon by an external force.
- Example: When a car suddenly stops, passengers continue to move forward due to their inertia until a seatbelt or airbag applies a force to stop them.
2nd Law (Law of Acceleration):
- The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Example: When pushing a heavy box and a lighter box with the same amount of force, the lighter box accelerates more because it has less mass.
3rd Law (Law of Action and Reaction):
- For every action, there is an equal and opposite reaction.
- Example: When you push against a wall, the wall pushes back with an equal amount of force.
It's important to note that these laws are foundational principles in classical physics and are widely applicable in understanding the behavior of objects in motion.

So this is the place where the path of the sun across the sky changes the
least during the year, and therefore the place where the lengths of day and
