Given :
An object with weight 20 N was lifted to 0.5 meters.
To Find :
How high must you lift a 25 Newton book for it to have the same increase in potential energy as the given book.
Solution :
Since both have same potential energy :
Putting all given values in above equation :
Therefore, book with same potential energy is at a height of 0.4 m.
1) <span>The function of the electron transport chain is to pump protons in the mitochondrion inter-membrane, thus building up a proton gradient. This gradient will allow the ATP syntheses</span><span>.</span>
2) Why we need oxygen for the electron transport chain:
At the end of the electron transport chain is the Oxygen that will accept
electrons and picks up protons to form water. If the oxygen molecule is not there the electron transport chain
will stop running, and ATP will no longer be produced. Basically, we need the oxygen to produce more ATP.
Water vapour and a drop in temperature to condense water vapour into a cloud. Something to see the cloud also, such as "pollution" particles.
Answer:
Current that reverses direction in the regular pattern is called an alternating current, abbreviated as 'AC'.
