Answer #1

Electron and hole concentrations in a semiconductor are generally many orders of magnitude less than those in metals

we know hall voltage is where n is charge concentration density which is very high for metals compared to semiconductors as I- current,B - magnetic field, e - charge of electron, d- width are given same in the question, so so semiconducters generate higher hall voltage than metals

Consider two very long conducting parallel wires carry currents in opposite directions such that one is triple of the other. The distance between wires is 30 cm. The magnetic field at points on a line between the wires, and at a distance of 5 cm from the wire carrying the smaller current, is 2.5×10-5 T. a) Draw a diagram of the situation. Assume the wires are placed in the x-direction. Draw the direction of the magnetic field at points on...

10 subjects in a study were randomly assigned into two equally sized groups. One group was shown a short video on how to fold paper cranes. The other group was given an instruction booklet on how to do so. They were then asked to make paper cranes for the next hour. The number of paper cranes each subject made was recorded and is listed in the table below. The researchers are interested in whether there was a difference in the...

An experiment is performed in deep space with two uniform spheres, one with mass 20.0 kg and the other with mass 108.0 kg . They have equal radii, r = 0.30 m . The spheres are released from rest with their centers a distance 40.0 m apart. They accelerate toward each other because of their mutual gravitational attraction. You can ignore all gravitational forces other than that between the two spheres. A. When their centers are a distance 28.0 m...
