The work done is 137 joules.
Lifting opposes the acceleration of gravity, which is 9.8 m/sec/sec.
20 x 0.7 x 9.8 = 137 J (kg-m2/sec2)
She should ask how far apart are the contractions, has your water broken, etc
Great Question! Mass is basically how heavy Something is. Most people confuse mass with weight but there very different from each other. Weight is the downward force something has because of gravity. Mass can be measured in a variety of units too. The second part of the question is how it affects density. It affects it because to find the density you need to be able to find the mass since the formula is Mass divided by volume. I hope this helped you understand a little bit more about mass. Have a great day!
Answer:
During photosynthesis, oxygen and hydrogen ions are formed from the splitting of water. To replace the electron, a molecule of water is split. This splitting releases the electron and results in the forming o oxygen and hydrogen ions. The hydrogen ions then get pumped into the inner thykaloid space and can be used to make ATP.
Explanation:
Hope this helps!
