M=147/9 x8 m=15kg
The mass of falling rock is 15kg.
<span>The natural source of acidity in rain water is all of the above. This is due to presence and abundance of carbon dioxide, nitrogen oxide, and sulfur dioxide in the atmosphere that can dissolve in rain water. Unpolluted rain water is made acidic due to CO2 and H2O in the air that forms carbonic acid.
Nitrogen oxide is mainly present due to the nitrogen fixation caused by lightning, while sulfur dioxide is mainly present due to volcanic eruptions. Other sources such as human activity can also contribute to acid rain. </span>
If you want the answer is centimeters is it going to be:
26.281 cm
If it make it easier for you to solve add 6.201 and 7.4 which will equal 13.601. Then add .68 to 13.601 which equals 14.281. Last add 12 to 14.281 which equals 26.281.
Hope this helps.
A the iodine spreads evenly throughout the water
Answer:
Explanation:
You need the conversion factor to convert the value of 12.33 kPa to milimiters of mercury, mmHg.
The converstion factors are looked at tables, which today you can find in internet.
Since the conversions between kPa and atm and between atm and mmHg are more widely known, I will show the conversion using those relations:
⇒ 101.325 kPa = 760 mmHg
Then, dividing both sides by 101.325 kPa you get the conversion factor:
- 1 = 760 mmHg / 101.325 kPa
Now, multiply 12.33 kPa by that conversion factor:
- 12.33 kPa × 760 mmHg / 101.325 kPa = 92.48 mmHg ← answer
