What are the three formulas (one formula rearranged three ways) which describe the relationship
1 answer:
Equation of Newton's second law of motion:
Explanation:
The equation that gives the relationship between force, mass and acceleration is Newton's second law of motion:
where:
F is the net force acting on an object
m is the mass of the object
a is the acceleration of the object
This equation basically tells that whenever there is a net non-zero force acting on an object, the object accelerates.
The equation can be re-arranged in three ways:
(1) (standard formula)
(2) Then we can re-arrange by making a the subject, and we get
(3) Then we can further re-arrange the make the mass the subject, and we get

Answer:
The magnifying power of this telescope is (-60).
Explanation:
Given that,
The focal length of the objective lens of an astronomical telescope,
The focal length of the eyepiece lens of an astronomical telescope,
To find,
The magnifying power of this telescope.
Solution,
The ratio of focal length of the objective lens to the focal length of the eyepiece lens is called magnifying of the lens. It is given by :
m = -60
So, the magnifying power of this telescope is 60. Therefore, this is the required solution.
