An electrically charged point particle with a mass of 1.85 x 10-6 kg is launched horizontally into a uniform electric field with a magnitude of 925 N/C. The particle's initial velocity is 6.82 m/s, directed eastward, and the external electric field is also directed eastward. A short time after being launched, the particle is 9.18 x 10-3 m below and 0.142 m east of its initial position. Determine the net charge carried by the particle, including the algebraic sign ( or -).

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?
