Suppose that an experiment determines that the amount of work required for a force field to move a particle from the point ( 1 , 2 ) to the point ( − 5 , 3 ) along the curve c 1 is 1.2 j and the work done by the field in moving the particle along another curve c 2 between the same two points is 1.4 j. what can you say about the field, and why? g

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
