Saline solution is a mixture of sodium chloride and water and has a number of uses in medicine. when administered via an iv drip it can be an effective treatment for dehydration. a cylindrical bag, as shown below, of radius 10 cm and height 50 cm contains saline solution that is provided to a patient as an iv gravity drip. a gravity drip is used to infuse the solution into the patient's blood stream. the solution flows downwards into a hole of 1 mm at the bottom of the bag. the only resistance presented is the viscous resistance through the tubing. determine the time it will take for the bag to empty by 90%.

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
