Hi there!
Normal rain has a pH between 5.0 and 5.5, which is slightly acidic on the pH scale. Acid rain on the other hand has an average pH of 4.0, much more acidic than your average rain.
Therefore, the most likely pH of acid rain would be 4.0.
Answer:
c) 2Q
Explanation:
From the given information:
The pressure inside a pipe can be expressed by using the formula:
Since the diameter in both pipes is the same, we can say:
where;
length of the first pipe A 
and the length of the second pipe B 
Since the difference in pressure is equivalent in both pipes:
Then:
Answer:
One reason is the positioning of the earth on its axis. The sun doesn't hit where we live in winter because we are pushed upwards more so we don't get the suns heat. The sun goes down earlier... so we don't have as much sunlight.
In winter the sun is father away from earth and in Summer it is closer...
Explanation:
Artificial gravity is created by rotating the cylinder
So here we can say that the acceleration is due to centripetal acceleration
So here we know that the formula of centripetal acceleration is given by
so here we know that
now we will plug in all values
So above is the radius of the cylinder
Now to find the diameter
so its diameter is 194.8 m
