1 pitch =100 micrometer /objective power
At 1000x
100 objective power x 10 eyepiece
So, ocular space=100/100=1um
100/1000=1/10
When you calibrated your eyepiece micrometer, you determined how many microns (µM) each eyepiece unit spans at each magnification level. Say you find that 18 eyepiece units span 100 µM when viewed under the 10x objective. How many microns (µM) long is a cell if it is 2 eyepiece units long under 1000x magnification? Show your work. Diagram the steps in performing an antibiotic disk diffusion assay.
Three equal charges are arranged in an equilateral triangle with side length of l=1.2 µm. Each charge has q=+2.0×10-11 C. How much energy was required to bring the charges into this configuration?
Review Questions 1 Why did you have to calibrate the ocular ruler at different total magnifications? In order to measure a secinrens rolate distance " the lines on the ocular nor. * You measure the length of a cell at 400x total magnification and determine it is 10 micrometers long. What is the length of this cell in millimeters? What is the length of this cell if you measure it at 1000X total magnification? Explain your reasoning 3. The figure...

PROBLEM Z Using the information below, construct a pedigree in the space provided and answer the following questions. Ocular albinism is inherited with the X-linked recessive allele a. The X-linked dominant allele A codes for full ocular color. George has ocular albinism. His wife Ginny has full ocular color. Both of Ginny's parents and both maternal grandparents (Ginny's mother's parents) have full ocular color but her great grandmother (the mother of Ginny's maternal grandmother) has ocular albinism. There is no...
Consider an equilateral triangle with sides of lengths 2.8 µm and charge −0.2 µC, 1.8 µC and 1.9 µC located at the corners of the triangle. Find the minimum work required to move the first point charge to infinity. The permittivity of free space is 8.85419 × 10−12 C 2 /N · m2 Answer in units of J.

. If 1 mm is equal to1/25,400 inch, convert the size of a bacterium measuring 3 µm X 1.5 µm to inches and Show your calculations.
2. A laser is sent through a pair of slits that are separated by 5.00 µm and have an identical, but unknown width. If there are 11 interference fringes between the two first-order diffraction minima, what is the width of each slit.
1.) Find the terminal velocity (in m/s) of a spherical bacterium (diameter 1.94 µm) falling in water. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.10 ✕ 103 kg/m3. (Assume the viscosity of water is 1.002 ✕ 10−3 kg/(m · s).
