12.) Formula: Effort Force x Effort Distance= Resistance Force x Resistance Distance While landscaping outside you come across a large stone and you have
the desire to lift this large stone that weighs 450 N and place it on other stones
for landscaping. The stone is too heavy for you to lift so you get a lever and a
fulcrum to execute your goal. If the resistance distance or the distance you hope
to lift the rock is.5m and the effort force you will exert is 200N. What far will you
have to push down on the lever to lift the large stone?

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Ithink it is a. but i'm not 100 percent sure.
