Answer:
<u><em>The correct option is C) the moon takes the same time to rotate and revolve.</em></u>
Explanation:
Scientific experiments have concluded that it takes approximately 23 days for the moon to rotate and also it takes the same duration for the moon to revolve around the Earth. Due to this consistency, the moon appears to be still.
<em>Such synchronization results in the same face of the moon to be directed towards the Earth. Hence, the same craters of the moon will be observed by the scientist every day.</em>
<em></em>
Other options, like option D, is not correct because there will be craters on the other side of the moon too. But as we see the same side of the moon, hence we cannot see the craters present on the other side of the moon.
Answer: its 15 its none of those
Explanation:
The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high will have:
Option B. A low and a high
This characteristic can be explained as:
- The concentrations of and are inversely dependent on each other so when the concentration of raises then the concentration of drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.
