Avertical electric field of magnitude 2.00 x 10^4 n/c exists above the earth’s surface on a day when a thunderstorm is brewing. a car with a rectangular size of 6.00 m by 3.00 m is traveling along a dry ravel roadway sloping downward at 10.00. determine the electric flux through the bottom of the car in the unit kn m2/c.

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
