1. Explain the following briefly. magnifying power of a microscope.

resolution of a microscope.

simple microscope

compound light microscope

electron microscope

Magnifying power of microscope is increasing the size of a object and show the multiplied size of an object from the original one.

Resolution of microscope is the ability of microscope to show the detailed structure of an object.

Simple microscope have only one lens system.

Compound light microscope have two lens system. These are eye piece lens and objective lens.

Electron microscope is a type of microscope that uses beam of electron to from an image.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.

this question your asking is true hope this and you get a 100 percent : )
