Along, straight wire lies along they­axis and carries a current 8.00{\rm a}in the ­y­direction . in addition to the magnetic field due to the current in the wire, a uniform magnetic field\vec{b}_0withmagnitude1.50 \times 10^{ ­ 6} \, {\rm t}is in the +x­direction. what is the magnitude of the total field at the point x= 0, z = 1.00 m in the xz­ plane?

The bottom of ignacio's desktop is 74.5cm from the floor. ignacios sits in his adjustable chair, and the tops of his legs are 49.3cm from the floor. each clockwise rotation of the knob on the chair raises ignacio's legs by 4.8cm. write an inequality to determine the number of clockwise rotations, r, ignacio could make with the knob without his legs touching the desk.
