Aresearch question must be all of the following except a. focused b. manageable c. broad d. researchable select the best answer from the choices provided a b c d

A research question is the principal subject to attend in a research work because the researcher should give an answer to satisfied the question.

Taking in consideration the statement before mentioned between the  answer options  is  C  because the question must be specific no  BROAD.

If the question is broad you could not finish the project search on time.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
