Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet. True When the bottom of the meniscus coincides with the calibration mark, your pipet contains a precisely measured volume. True e Do not force the pipet into the pipettor, be gentle. Excessive force may cause the pipet to break and could potentially cut you while trying to insert or remove the pipet.…

Let C(t) be the carbon dioxide level in parts per million in the atmosphere where t is the time in years since 2000. Under two possible models the derivative functions are 1. C'(t)=0.45 +0.03 11. C'(t)=0.45e0.025 If the carbon dioxide level was 370 ppm in 2000, find C(t) for each model. Then find the carbon dioxide level in 2030 for each model. Using Model I, C(t) Using Model II., C(t) and the carbon dioxide level in 2030 is C(30) - ppm. and the carbon dioxide level in 2030 is C(30)-pp ppm.
