The total electric field E consists of the vector sum of two parts. One part has a magnitude of E1 = 1248 N/C and points at an angle θ1 = 40° above the +x axis. The other part has a magnitude of E2 = 1578 N/C and points at an angle θ2 = 53° above the +x axis. Find the magnitude and direction of the total field. Specify the directional angle relative to the +x axis.

An aircraft performs a maneuver called an "aileron roll." during this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. if it takes it 35 s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wing tip

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons
