A uniform 120 lb beam is supported in a horizontal position by a pin and cable as shown in the figure. a)Write the expression magnitude of the force by the pin on the beam. b) Calculate the magnitude of the force by the pin on the beam.

What is magnetic flux? explain faraday's law of induction.

What is the magnitude of the resultant vector round your answer to the nearest tenth

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
