Determine the volume of fluid in the graduated cylinder shown.
22 ml
22.5 ml
23 ml
23.0 ml

22.5 mL

Explanation:

We are given an amount of a fluid in a graduated cylinder and required to determine its volume.

Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.

The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL

i would say b

explanation:

but i think i would need more information than that

particle   p is an electron and particle q is a neutron
