You have a set of calipers that can measure thicknesses of a few inches with an uncertainty of ± 0.005 inches. You measure the thickness of a deck of 52 cards and get 0.590 in: a.

Which of these best describes the difference between energy and power?

How do I find the final velocity with momentum?

Why are electrons not included in the atomic mass of an atom? because electrons do not have an important function in atom because eletrons are so extremely small that they do not affect the mass because electrons have more mass than protons neutrons

Is erosion a constructive or destructive force and why?
