At the surface of the ocean, the water pressure is the same as the air pressure above the water, 15 pounds/square inch. As you descend below the surface of the water, the water pressure increases by 0.434 pounds per square inch for every 1 foot of descent. Define a function j that determines the water pressure in terms of the number of feet you are below the surface of the water, n. (Don't forget that the water pressure is 15 pounds/square inch at the surface).

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: do we write it

step-by-step explanation:

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
