Answer: Option (a) is the correct answer.
Explanation:
When rain passes through the air then carbon dioxide present in the air dissolves in the water. Further, this carbon dioxide reacts with water and results in the formation of carbonic acid.
Thus, the rain water becomes acidic in nature and as a result, there will be decrease in its pH.
Hence, we can conclude that rain has a natural pH that is acidic.
Answer:
the square of the average atomic velocity.
Explanation:
From the formulas for kinetic energy and temperature for a monoatomic gas, which has three translational degrees of freedom, the relationship between root mean square velocity and temperature is as follows:
(1)
Where
is the root mean square velocity, M is the molar mass of the gas, R is the universal constant of the ideal gases and T is the temperature.
The root mean square velocity is a measure of the velocity of the particles in a gas. It is defined as the square root of the mean square velocity of the gas molecules:
(2)
substituting 2 in 1, we find the relationship between mean square speed and temperature:

Answer:
50%
Explanation:
Efficiency = work out / work in
e = Fd / W
e = (2000 N) (2 m) / (8000 J)
e = 0.5
Base in your question that ask for the distance that the remote control would extend beyond the edge where as a remote control is 22cm long and has a mass of 0.08kg =, base on my calculation the answer would be 1.27cm i hope you understand my answer
Answer:
196.34 °F
Explanation:
To convert from degrees celsius to degrees fahrenheit, use this equation:
(°C * 9/5) + 32 = °F
So, using this equation:
(91.30 * 9/5) + 32 = °F
196.34 + 32 = °F
°F = 196.34
Hope this helps!
