<span>At bedtime last night, I had to make a serious and tough decision:
I could either sleep on the couch, under the pile of dogs who act
as if they own the place, or else I had to defy gravity and raise my
mass
upward to the second floor of my house, where my bedroom
is located. I decided to sleep in my own bed, and I overcame the
force of gravity and lifted my entire mass up the stairs to the second
floor. I
used my leg muscles to do the job.

To solve this problem, we will start by defining each of the variables given and proceed to find the modulus of elasticity of the object. We will calculate the deformation per unit of elastic volume and finally we will calculate the net energy of the system. Let's start defining the variables
Yield Strength of the metal specimen

Yield Strain of the Specimen

Diameter of the test-specimen

Gage length of the Specimen

Modulus of elasticity



Strain energy per unit volume at the elastic limit is



Considering that the net strain energy of the sample is




Therefore the net strain energy of the sample is 
Wavelength, because of how it lengths out from the rest.
Answer:
Check the explanation
Explanation:
Kindly check the attached image below to see the step by step explanation to the question above.
Answer:
As Per Given Information
20x objective lens was used by specimen
10x ocular lens was also used by him.
we have to find the total magnification.
For calculating the total magnification we 'll simply do multiplication
Total Magnification = 20x × 10x
Total Magnification = 200x
So , the total magnification will be 200x .
