PLS HELP The graph describes how the solubilities of two salts change as water temperature changes. Which two statements are true, based on the relationships shown in the graph?
Α. Potassium nitrate’s solubility increases much more than sodium chloride’s as water temperature increases.
B. Sodium chloride’s solubility is greater in cold water than in hot water.
C. More sodium chloride than potassium nitrate can dissolve in cold water.
D. Less potassium nitrate than sodium chloride dissolves in hot water.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
