The overall magnification of a compound microscope with an objective lens magnification of 5 and an eyepiece magnification of 30 will be

a. 6.
b. 100.
c. 150.
d. 280.

I believe the answer is 150. Total or overall magnification of a compound light microscope can be Calculated by this.

Total mag=(obj lens magnification)x(eye piece magnification).

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
