This figure depicts pollen grains suspended in a liquid exhibiting a continual, erratic motion known as Brownian motion. Albert Einstein inferred that atoms exist based on his calculations that described this type of motion. What was the basis for his conclusion?
a. The erratic motions of the pollen grains were explained by Einstein to result from random collisions with water molecules.
b. The tiny grains could be shown to be atoms.
c. The existence of atoms was an inescapable conclusion of his theory of relativity.
d. The existence of atoms was an inescapable conclusion of his theory of the photoelectric effect.
e. The existence of atoms was an inescapable conclusion of his theory of heat capacities of solids.

When 4 V of potential difference is applied across Resistor A, 2 A of current flows through it. When 4 V of potential difference is applied across Resistor B, 1 A of current flows through it. When 12 V is applied across Resistor A, 6 A flows through it, and when 12 V is applied across Resistor B, 3 A flows through it. Which of the following is consistent with this data?
1.Both resistors are not ohmic. 2.Resistor A is ohmic but Resistor B is not. 3.Resistor A is not ohmic but Resistor B is. 4.Both resistors are ohmic.
