Answer:
Explanation:
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.
Answer:
107 kJ
Explanation:
12.00 kg * 913 J /kg-C * (118-20)°C ( I corrected spec heat units)
( a C degree change is the same as a kelvin change)
= 1 073 688 J = 107 kJ ( three sig digits)
If magnification is less than one it means the image is the same exact size as the object.
