The lower end of the thin uniform rod in (Figure 1) is attached to the floor by a rictionless hinge at point P. The rod has mass 0.0920 kg and length 20.0 cm and is in a uniform magnetic field 0.190 T that is directed into the page. The od is held at an angle 56.0° above the horizontal by a horizontal string that connects the top of the rod to the wall. The rod carries a current 12.0 Ā in the direction toward P. Part A Calculate the tension in the string. Use the fact that T=IBL? for a uniform bar of length L carring a current I in a magnetic field B. Express your answer with the appropriate units. B) ?

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
