Answer:
Graph B shows the solubility of gas dissolved in a liquid.
In graph B the temperature is increasing and solubility decreases
So, when temperature increases the molecules of the gas becomes free their kinetic energy increases.
Hence, their solubility decreases they will be more present in the form of vapors.
Therefore, Option B is correct that is gas dissolved in a liquid.

Answer: 240 ft/sec
Explanation:
If the distance s, of the car regarding his starting position, is defined as a function of time, by definition, the instantaneous velocity at any time, is given by the derivative of the displacement (distance from origin) respect the time, as follows;
v = ds / dt ⇒ v= d/dt (5 t³) = 15 t² = 15 t²
Replacing by t=4 s, we get:
v = 15. 4² = 15.16 = 240 ft/sec
