A Hall effect experiment is performed on a semiconductor with a length of 2.65 cm and width=height=1.70 cm, in a magnetic field of 0.5 T. The current in the sample along its length is 200 µA. The potential difference along the length of the sample is 195 mV and across the width is 21.4 mV. The charge carriers are positive so that the contribution of electrons is ignored. Sketch the experiment ensuring that you note the directions of currents and fields correctly. What is the concentration of the positive charge carriers? If the sample has a resistivity of 10

The following graph shows the velocity of a ball moving along a straight line. When the ball moves to the right its velocity is positive, and when it moves left the velocity is negative. Compute the object’s change in position (in cm) from to [x] seconds. Do not include units in your answer. The units of your answer should be ‘cm’.  Input the numerical value only.
