What is the difference between systolic and diastolic pressure?

The difference between the systolic and the diastolic pressure is the pulse

Explanation:

Systolic blood pressure is the top number of the maximum pressure your heart exerts while beating (systolic pressure),

and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure).

The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.

Hence systolic - diastolic = pulse

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
