While john is traveling along a straight inter-
state highway, he notices that the mile marker
/reads 256 km. john travels until he reaches
the 138 km marker and then retraces his path
to the 173 km marker.
what is john's resultant displacement from
the 256 km marker?
answer in units of km.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

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

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp, max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
