Answer:
The correct answer is - 43%.
Explanation: The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.
Answer:
a) the velocity increases then decreases.
Answer:
The mass of water is 
Explanation:
Given that,
Area of town = 29 km²
Time = 30 min
Height = 2.4 inch
Mass = 103 kg
We know that,
1 m = 39.37 inch
So, 
We need to calculate the volume
Using formula of volume
Put the value into the formula
We need to calculate the mass of water
Using formula of density
Put the value into the formula
Hence, The mass of water is
Answer:
4.08 kg
Explanation:
We can apply the Newton's second law of motion to find the mass of this object:
,
where 
is mass, and 
is acceleration, which is substituted by 
here. Now, plugging given numbers in the equation, we have
.
Solving for mass, we have
