Answer:
Explanation:
We know Haley is driving with an initial velocity of and then she has to change to a velocity of
in a distance
, and we also know we are dealing with constant acceleration
.
Therefore, the following equation will be useful:
(1)
Clearing :
(2)
(3)
(4)
Knowing and
:
this is the constant acceleration that will bring Haley to lower speed
Answer:
The angle is
Explanation:
From the question we are told that
The objective focal length
The eyepiece focal length is
The diameter of the sunlight is
The distance of the sun from from the earth is
Generally the magnification of the object is mathematically evaluated as
The negative sign is because the lens of the telescope is diverging light
substituting values
Now we can obtain the angle made by the object (sunlight ) with respect to the telescope as follows
substituting values
The magnification can also be mathematically represented as
Where is the angle the image made with telescope
Since the negative sign indicate direction of light movement we will remove it from the calculation below
