Do you have a book about it? or if you have a dictionary?
Global warming, acid rain and general air pollution from car exhaust occurs from burning fossil fuels. The global warming occurs because of a "green house effect" where sunlight is trapped inside our atmosphere due to air pollution. Acid rain occurs when the products of combustion, sulfur dioxide, nitrous dioxide and nitrogen dioxide mix with rain water.
Each of these impacts is very extensive. Each fossil fuel has individual impacts related to their use
Answer:
Autobus porusza się ze stałą prędkością 54 km/h Oblicz w jakim czasie przebędzie drogę 450 m
Answer:
v = 6.95 m/s
Explanation:
Given that,
A diver is on a board 1.80 m above the water, s = 1.8 m
The initial speed of the diver, u = 3.62 m/s
Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :
So, she will hit the water with a speed of 6.95 m/s.
Answer:
30.4 s
Explanation:
A pilot , with plane accelerated at 4 g starts greying out . In the problem , the acceleration of jet is 4 g
a = 4 x 9.8 = 39.2 m /s²
initial velocity u = 0
Final velocity = 3.60 times speed of sound
= 3.6 x 331 = 1191.6 m /s
v = u + at
Putting the values
1191.6 = 0 + 39.2 t
t = 30.4 s .
