Two long, parallel, current-carrying wires lie in an xy-plane. the first wire lies on the line y = 0.330 m and carries a current of 26.5 a in the +x direction. the second wire lies along the x-axis. the wires exert attractive forces on each other, and the force per unit length on each wire is 300 µn/m. what is the y-value (in m) of the line in the xy-plane where the total magnetic field is zero?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
