As more resistors are added in parallel, the total current strength increases.  Jay adds more resistors in parallel to a circuit. The total current strength decreases or increases?
increases


(Question)
Fossils found at the lowest layer of rock would be the oldest, as these would have been buried for the longest time, whereas fossils found closer to the surface would be buried more recently and therefore be younger.  Peter found a cool rock very deep below the surface of some dirt. He knew the rock was older or younger?
(Answer)

Ques:As the amount of water increases, the melting point of rock decreases.  Richard dropped two identical rocks, one into a puddle, and the other into a swimming pool. After dropping both rocks, the rock dropped into the swimming pool had a higher melting point than the other rock or a lower melting point than the other rock?

Ans:a lower melting point than the other rock


Longer length resistors will offer more resistance than shorter resistors.  Ed is adding a resistor to a circuit. If he needs it to have more resistance, he should add a resistor that is shorter. or longer?
longer
