Explanation / Answer

4. From the given data, Magnification is 300X.

Magnification = Size of object / actual size of object

300 = 1.5 / Actual size of object

Actual size of object = 1.5 / 300 = 0.005cm.

5. Total magnification is always a product of magnification of ocular lens and magnification of objective lens.

And Field of view in mm for 40X magnification is 5mm

Field of view in mm for 100X magnification is 2mm

6. No. Dissecting microscope doesn't have a condenser.

7. 1lb = 0.453592 kg

170 lb = 0.453592 X 170 = 77.1107 kilogram

8. 1 metre = 3.28084 foot long

100 metre = 3.28084 X 100 = 328.084 feet
