You walk 3-4 steps to pick up an object, you bend and arise and gain control (grasp) of the light object. You move the object to a distance within reach without any body motion. You place the light object with light pressure and return the 3-4 steps to you original starting location. Show the results in both TMU and seconds.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
