False. Acids are actually found in the pH range from 0 to 7 and bases are found from 9 to 14. Meanwhile, 7 and 8 are considered neutral.
Answer:
C) scientist use experiments to test their ideas
Explanation:
Resistance = Resistivity * Length / Area
= 30 * (1/3) / (1/4)
= 40x.
Hence the resistance of the constant wire is 2 * 40 = 80 ohms.
