C. Remove 0.5 mL of liquid.
Explanation:
When measuring the volume of a liquid with a graduated cylinder, you need to measure from the bottom of the meniscus (the curve).
After observation, the volume of the liquid is 13 mL. Therefore, in order to get the desired volume of 12.5 mL, remove 0.5 mL of liquid.

what would happen if 15 joules of work is done on an object that has 90 N of force applied to it
Answer:
The magnitude of the force is given by F = ma = (10)(5) = 50 N. It acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50)(20) = 1000 Joules.
