Answer:
Explanation:
mass of baseball, m = 0.145 kg
initial velocity, u = 12 m/s upward
(a) final velocity, v = u / 2 = 6 m/s
Let the height is h.
Use third equation of motion
v² = u² - 2gh
6 x 6 = 12 x 12 - 2 x 9.8 x h
36 - 144 = - 19.6 x h
h = 5.51 m
(b) initial kinetic energy, K = 0.5 x m x u² = 0.5 x 0.145 x 12 x 12 = 10.44 J
Final kinetic energy, K' = K/2
0.5 x m x v² = 10.44 /2
0.5 x 0.145 x v² = 5.22
v = 8.5 m/s
v² = u² - 2gh
8.5 x 8.5 = 12 x 12 - 2 x 9.8 x h
72.25 - 144 = - 19.6 x h
h = 3.66 m
Answer:
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Answer: Boyle’s law
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
As pressure is decreased to half, the volume is increased to doubled.
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)
Combined gas Law: combining the three laws:
