1) Based on this graph of force vs. extension for a certain spring, what should be the Hooke's law constant (or spring constant)
?
Show the full calculation using data from the figure, and report the answer in N/m.
2) Suppose a 250 g mass was hung from the spring in the previous question. What would be the extension of the spring when it is in equilibrium and at rest?
Write the equation needed to answer this question and the solve for the extension, recording the answer in either m or cm.
3) Now the 250 g mass hanging from the spring in the previous question is pulled down an extra 10 cm and released. What would be the period and the counting frequency of the oscillations?
Once again, begin with an equation and show the steps needed to find the answers.

Complete Question
The distance between the objective and eyepiece lenses in a microscope is 19 cm . The objective lens has a focal length of 5.5 mm .
What eyepiece focal length will give the microscope an overall angular magnification of 300?
Answer:
The eyepiece focal length is
Explanation:
From the question we are told that
The focal length is
This negative sign shows the the microscope is diverging light
The angular magnification is
The distance between the objective and the eyepieces lenses is
Generally the magnification is mathematically represented as
Where is the eyepiece focal length of the microscope
Now making the subject of the formula
substituting values
