Calculate the force on an electron in each of the situations below. (a) moving at 1.7 percent the speed of light and perpendicular to a 3.0 T magnetic field. (b) 3.9 ✕ 10-6 m from a proton. (c) in Earth's gravitational field at the surface of the Earth. Use the following: qe = -1.6 ✕ 10-19 C; me = 9.1 ✕ 10-31 kg; qp = 1.6 ✕ 10-19 C; qp = 1.6 ✕ 10-19 C; c = 3.0 ✕ 108 m/s; kC = 9.0 ✕ 109 N·m2/C2

Does this organism still meet the definition of a eukaryote ? why or why not?

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.
