Answer:
a) p = 4.167 cm, b) m = + 6
Explanation:
a) For this exercise we must use the equation of the constructor
where f is the focal length, p and q are the distance to the object and the image, respectively
In this case the distance to the image q = 25 cm and the focal length is f = 5.0 cm
Since the object and its image are on the same side of the lens, the distance to the image by the sign convention must be negative.
= 024
p = 4.167 cm
b) angular magnification
m = h ’/ h = - q / p
m = - (-25) /4.167
m = + 6
the positive sign indicates that the image is straight and enlarged
We would only know that if we could see it.
So far, with the most sensitive astronomical instruments that have
been built, we don't see an end as far away as we can see.
The farthest (dimmest) objects we can see are something like
13-1/2 billion light years away.
A stone is thrown straight up. While the stone is rising: Group of answer choices its acceleration is upward and decreasing its acceleration is upward and constant its acceleration is upward and increasing its acceleration is zero None of the available answers are correct. its <u>acceleration </u><u>is zero</u>
<h3>What is
acceleration ?</h3>
The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.
According to Newton's Second Law, the amount of an object's acceleration depends on two factors: the net balance of all external forces acting on the object; the magnitude of the acceleration is directly proportional to the net resulting force. For instance, when a vehicle begins at rest (zero velocity in an inertial frame of reference) and moves straight ahead at increasing speeds, it is accelerating in the direction of travel.
