The table below compares the solubility of two substances in 100 milliliters (mL) of water. SOLUBILITY OF SUBSTANCES

Solubility Temperature l Sucrose l Hydrochloric acid
l Grams/100mL water l Grams/100mL water

Solubility at 20°C l 204 l 720
Solubility at 100°C l 488 l 989

Based on the table, which of the following statements is true?

The solubility of sucrose increases if more is dissolved.

The solubility of sucrose decreases as temperature increases.

The solubility of hydrochloric acid increases if more is dissolved.

The solubility of hydrochloric acid increases as temperature increases.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
