Avery long wire carries a uniform linear charge density of 5 nc/m. what is the electric field strength 13 m from the center of the wire at a point on the wire's perpendicular bisector? (ε 0 = 8.85 × 10-12 c2/n · m2)

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
