Which statements accurately explain the physiology of oxygen ($$O_2$$) and carbon dioxide $$CO_2$$ exchange in the lungs? Select all that apply. 1. The thinness of the alveoli allows for diffusion of gases across their membranes. 2. $$CO_2$$ diffuses from the pulmonary capillaries into the alveolar sacs. 3. Diffusion of $$O_2$$ occurs due to the capillary $$O_2$$ concentration being lower than of the air in the alveoli. 4. $$CO_2$$ moves from the alveoli to the blood in the capillaries. 5. The stretching of alveolar walls allows carbon dioxide to be exhaled out.

RTD Interface Problem #2: The circuit below was briely discussed earlier in the course. This is an RTD interface which means it is fundamentally an ohmmeter. The block X1 develops a known current of 1mA which will then develop a voltage across the RTD (R5). The resistors R1-3 represent the resistance of the "lead" wires going out to the RTD which is typically located a long distance (100's to 1000's of feet) from the shown circuit. Assume you need to reverse engineer this circuit to determine what blocks 1-3 are doing. So describe the outcome of your reverse engineering and the purpose of every component in those blocks with the exception of R11 which will be discussed in a future lecture. 1mA X1 VCCVCC VEEVEE VIN IOUT block 01 LT1097 R5 500 ? block 1 tran 0 10m 0 startup U2 40.2k LT1097 12k block 3 0.22µ 3.74k CC Yout TLT1097

Please help asap. I will like you to consider the initial value problem: 3y = 36, y0 = 2. To solve this, I will first find the general solution of the corresponding algebraic equation. Let's denote the left-hand side of the equation as L and the right-hand side as R. Do not move any terms from one side of the equation to the other until you reach part (b) below.
