The charge on one electron is 1.6 x 10^-19 Coulombs. The electron beam in an oscilloscope has 3.4 x 10^7 electrons flowing per second and the accelerating voltage is 15 kV. What is the effective resistance of the space the electrons flow through?

If 2 different solids have the same masses but different volumes, how will their densities compare? a. the solids will have the same densities. b. the solid with lower volume will have a higher density. c. the solid with greater volume will have a higher density. d. the solid with greater volume will have double the density of the solid with the lower volume.
