Which of the following describes pressure in a fluid ?
a. pressure increases with increasing depth
b. pressure remains unchanged with increasing depth
c. pressure varies randomly throuout a fluid
d. pressure decreases with increasing depth

the answer is c i did the same question so i know that's right!

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
