An iron block of density Fe and of volume l3 is immersed in a fluid of density fluid. The block hangs from a scale which reads W as the weight. The top of the block is a height h below the surface of the fluid. The correct equation for the reading of the scale is
 a. W = (Fe  fluid)ghl2.
  b. W = (fluid  Fe)gl3.
  c. W = (Fe  fluid)gl3.
  d. W = (Fe + fluid)ghl2.
  e. W = (Fe + fluid)gl3.

Question 2

Melanie says that when a diver enters an underwater cave of height h, the pressure on her is no greater than Wgh. Rosalind says that if the bottom of the cave is a distance H below the water surface, the pressure on the soles of the diver's feet can reach WgH. Which one, if either, is correct? (The density of water is W.)
 a. Melanie, because the roof of the cave absorbs the water pressure from above.
  b. Melanie, because only the fluid directly above any volume of the fluid can contribute to the pressure on that volume.
  c. Rosalind, because a fluid exerts equal pressure in all directions at a given depth.
  d. Rosalind, because the pressure also depends on the density, c, of the material above the cave roof, so that p = cg(H  h) + Wgh.
  e. Melanie, because the pressure equals p = WgH  cg(H  h).

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

To maintain good kidney function, you should drink at least 3 quarts of water daily. Water dilutes urine and helps prevent concentrations of salts and minerals that can lead to kidney stone formation. Chronic dehydration is a major contributor to the development of kidney stones.

For high blood pressure (hypertension), a new class of drug, called a vasopeptidase blocker (inhibitor), has been developed. It decreases blood pressure by simultaneously dilating the peripheral arteries and increasing the body's loss of salt.

All patients with hyperparathyroidism will develop osteoporosis. The parathyroid glands maintain blood calcium within the normal range. All patients with this disease will continue to lose calcium from their bones every day, and there is no way to prevent the development of osteoporosis as a result.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
