The gure below shows a rectangular loop placed in a magnetic eld B (shown as orange horizontal lines) created by the magnets in the gure. Let the long side of the loop be: and the short side be to. In each of the gures (a) and (b) assume that the loop is at rest in the orientation shown and a current I is then passed through each loop. Imagine that the gap in Side 4 of the loop is very small and you can treat Side 4 as a continuous segment. 5 pts |. Draw the direction of the current I through each segment. ||. Draw the area vectorA for this loop. I\". Draw the directions of the magnetic forces on Sides 1, 2, 3 & 4. You may use the boxes to indicate the direction of the forces on Sides 1 and 3. IV. Symbolically write the magnitude of each force in terms of I, l? w 35 B. V. What is the effect of all the magnetic forces on the loop's motion? Will the forces result in translational motion, rotational motion, or oscillatory motion? Explain. If there is translational motion, indicate its direction in the gure. If there is rotational motion, label the axis of rotation and the direction of rotation about this axis. VI. lfl = 14 A, the long side equals 20 cm and the short side = 16 cm, and B=1.2 T, calculate the magnitude of torque in (a). Show the formula used. A recreational diver descends to 220 feet and stays there for some time. 5pts (3) What absolute pressure do they experience at this depth? Show the physics approach used. (b) How much larger is the pressure compared to the atmospheric pressure? 1 atm = 1.013 x 105 Pa Density of water = 1000 kg/m3 1 foot = 0.3 m A patient has suffered blood loss and a health care provider is preparing a saline solution for injection. The osmotic pressure of red blood cell is 6.95 atm, and the prepared solution should be isotonic with those cells. 5 pts Note: Body temperature is 37.15" C and that the gas constant R is 8.206 x 10'2 (L -atm)/(K -mol). a) To prepare the saline solution, how many moles n of solute should be put into 2.5 L of distilled water? Write the formula. b) Mistakenly, the concentration of the solution is only 5/4 of what it should be. What would be the net osmotic pressure = osmotic pressure inside the cell - osmotic pressure of the solution, exerted on the walls of the red blood cells? c) What effect would this have on the net ow of water into the cell? What are the implications of this
