I"m being timed me! -when you push on the object, the object moves. what is the reaction against your skin? -what is zero net force? -what is the basic principle of newton's 3rd law? will mark

Zero net force is when forces are balanced, ie no velocity.

All forces put on an object have an equal and opposite reaction.

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.
