Which factor is most important to keep the same when comparing the hardness of solids?
A. The intensity of the light
B. The temperature of the hot plate
C. The method of making a scratch on the material
D. The amount of each substance

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

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .

The answer is b on edgenuity
