# homework help

pls help me on these questions its for an assessment thank u have a nice day!

This scale represent 5 upside down hm calculate the magnification factor.

A student is looking at diagram of a red blood cel.. the diagram tells him that the cell has a magnification of x5000. The student then measures the size of the image and finds that it is 7mm long.

A) what equation would the student need to use in order to calculate size?
B) calculate actual size in nm
c) An object 4.55mm wide is viewed under a 600x magnification how wide is the image?
D) an object is 20 upside down hm long is viewed under a 2000x microscope - how long is the image>
E) a sample of food infected with bacteria is viewed under the microscope. The bacteria area 0.5 upside down hm long how big will they look when using a light microscope which has a magnification of 1500x explain If this a good use of a microscope?

F) an atom is 0.1nm wide when viewed under an electron with a magnification of x 10.000.000 how wide will it look? Give ur answer using standard form and explain. If this is a good use of microscope

You need part a) to answer the rest of the questions so
Image = actual x magnification
1000 nanometres = 1 micrometer
1000 micrometers = 1 mm
1000 mm = 1 m
Convert to the same units
Remember the definition for resolution (ability to differentiate between 2 adjacent object as seperate)
