most commonly occurs because of the frequent pumping of water from the ground.
Explanation:
Stop using it all the time for some useless things.
The unit conversion factors are always a power of ten. It is very easy to get different measurements quickly.
Answer: The answer is 1.5 hours.
Step-by-step explanation: Given that the pilot took 1/2 hour to complete 1/3rd of his trip. We are to calculate the time that he will take to complete his trip.
Time taken by the pilot to complete 1/3 rd of his trip = 1/2
Therefore, time taken by the pilot to complete his trip is given by

Thus, the pilot will take 1.5 hours to complete his trip.
The pressure of the water on the diver is given in an expression written as:
<span>p=15+15/33d
where p is the pressure and d is the distance of the diver </span><span>below the surface.
The pressure is calculated as follows:
</span>p=15+15/33(100) = 15.00 pounds per square feet
Therefore, the correct answer is option A.
