Question1

In the cooper and Shepard experiment 1973 participants were asked to choose whether a stimulus a letter was normal simply rotated in the picture plane or backwards flipped to its mirror image before the rotation. Reaction times were graphed and increased as the letters were rotated away from 0 m degrees. Interestingly, reaction time decreased after 180 degrees. Describe why this may occur?

Question2

A horizontal desk surface measure 1.3 m * 1.0 m. If the Earth's magnetic field has magnitude 0.44 m T and is directed 65 degrees below the horizontal, what is magnetic flux through the desk surface?

Question3

An air-filled toroidal solenoid has a mean radius of 20.0 and a cross-sectional area of 7.00. When the current is 11.0, the energy stored is 0.450. How several turns do the winding have?
