Two long, parallel wires are attracted to each other by a force per unit length of 340 µn/m. one wire carries a current of 15.5 a to the right and is located along the line y = 0.490 m. the second wire lies along the x axis. determine the value of y for the line in the plane of the two wires along which the total magnetic field is zero.

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

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?
