A system consists of electrons and protons only. It contains 301 protons and has a total charge of −51e. What is the mass of the system? me=9.11×10^−31kg, mp=1.673×10^−27kg.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Which best describes the difference between internal and thermal energy?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
