For a nonsmoker, normal blood flow requires a pressure difference of 8.0 mmHg between the two ends of an artery. Assume that smoking increases viscosity by 10% and reduces the arterial diameter to 90% of its previous value. For a smoker, what pressure difference is needed to maintain the same blood flow?

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

wavelength divides in half and speed stays the same.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
