the blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one fifth its normal cross sectional area. What is the difference in blood preassures between the normal and constricted segments of the artery. The density of the blood is 1060

286.2  pa

Explanation:

Blood speed in a normal segment of a horizontal artery ( v2 ) = 0.15 m/s

Density of blood = 1060 kg/m^3

Normal sectional area = A2

constricted sectional area ( A1 )= 1/5 A2

Determine the difference in blood pressures between the normal and constricted segments

we will apply Equation of continuity     Av = constant

Δ p = 12 PV^2

     = 12 * 1060 * ( 0.15 )^2

     = 12720 * 0.0225  =  286.2  pa

attached below is a detailed solution of the Given problem

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
