Answer:
Acceleration = 3m/s^2
Displacement = 126 m
Explanation:
The velocity changed from 12 to 30 m/s in 6 seconds. Using the formula for acceleration we get
(30-12)/6= 18/6= 3m/s^2
Displacement is d=.5a*t^2+v0*t
Inputting acceleration, time, and velocity leaves us with
d=1.5 * 36 + 12 * 6 = 54 + 72 = 126 m
Acid rain is rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.
Answer:
Thermocline.
Explanation:
The sunlight does not reaches deep inside the water called as the deep layer in which the temperature of water is low and it is cold. These two layers are separated by the middle layer called as the thermocline, which is warm at the top and cold at the bottom.
