Ques: We also saw that adding resistors to a series circuit increases the total resistance of the circuit, causing the current to decrease.  Jim loves to build circuits. One day he builds a circuit that has less resistors then any other circuit he has built. Since the circuit has less resistors the amount of current in the circuit is reduced or increased?
Ans: increased

Ques: The closer together the particles in a longitudinal wave are, the greater the amplitude.  If Mona creates a longitudinal wave and decreases the distance of the particles in the wave, what happens to the amplitude of that wave increases or decreases?
Ans: increases

Ques: The more efficient a device is, the greater the percentage of usable energy it produces.  If a device were to become less efficient, it would produce more or less usable energy?
Ans: less

Ques: During inhalation, because the chest volume is larger, the air pressure inside the lungs is lower than the air pressure outside.  Compared to a balloon that has the size of a head a balloon the size of a fist will have more pressure or less pressure?
Ans:
more pressure
