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 -).

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
