Ah electron is a negatively charged particle that has a charge of magnitude, e - 1.60 x 10-19 c. which one of the following statements best describes the electric field at a distance r from the electron? the electric field is directed away from the electron and has a magnitude of ke/r. the electric field is directed toward the electron and has a magnitude of ke/r. the electric field is directed toward the electron and has a magnitude of ke/12 the electric field is directed away from the electron and has a magnitude of ke/2 the electric field is directed toward the electron and has a magnitude of ke? /r.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
