The Hall affect is used to measure the carrier density of a thin sheet of electrons. When a current of 8.0 A flows through the 12-mm thickness electron sheet, a magnetic field of 0.75 T perpendicular to the sheet produces a voltage of 0.53 mV across the width of the sheet. What is the carrier density in the electron sheet?

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

The strong nuclear force acts over a small distance than the electrostatic force. true or false

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
