When drawing up liquid into a micropipette, put the tip in the liquid at a Choose... degree angle, push the plunger to the Choos
e... point of resistance, and then Choose... the plunger. When dispensing that liquid from the micropipette, hold the micropipette at a Choose... degree angle in the desired container and push the plunger to the Choose... point of resistance. Choose... the plunger until dispensing is done.
This question seeks to test the knowledge of operating a micropipette.
When trying to draw a liquid from a container using a micropipette (tip), the micropipette should be <u>held vertically straight at an angle of 90 degrees</u> with the plunger pushed to the <u>first resistance</u> and then released.
When trying to dispense the drawn liquid into another container, the micropipette is <u>held vertically straight at the same 90 degrees</u> but the plunger is pushed to the <u>second/last</u> point of resistance. <u>You keep pressing</u> the plunger at the same degree and resistance until dispensing is done.
The correct answer is letter A. 6 millimeters. <span>If an object 18 millimeters high is placed 12 millimeters from a diverging lens and the image is formed 4 millimeters in front of the lens, the height of the image is 6 millimeters. </span> Solution: 18 / x = 12 / 4 12x = 72 x = 6mm
Displacement is a vector that defines the position of a particle. The vector extends from the initial position to the final position. Therefore, the displacement only takes into account this positions, since its trajectory is not important:
