The hall effect can be used to calculate the charge-carrier number density in a conductor. if a conductor carrying a current of 2.0 a is 0.5 mm thick, and the hall effect voltage is 4.5 µv when it is in a uniform magnetic field of 1.2 t, what is the density of charge carriers in the conductor?

The speed of light can be used to measure the

Which statement is true if the refractive index of medium a is greater than that of medium b? a. total internal reflection is possible when light travels from air to medium b to medium a. b. total internal reflection is possible when light travels from medium a to medium b. c. total internal reflection is possible when light travels from medium b to medium a. d. total internal reflection is possible when light travels from air to medium a. e. total internal reflection is possible when light travels from air to medium b.

10. the kinetic theory of matter states that atomic particles will move if the temperature is above the freezing temperature of water atomic particles bounce off each other one time in their life atomic particles are constantly bumping off each other because particles are in direct contact with each other at all times all matter is made up of atomic particles which are in constant random motion
