Gas is confined in a tank at a pressure of 11.9 atm and a temperature of 23.0°C. If two-thirds of the gas is withdrawn and the temperature is raised to 76.0°C, what is the pressure of the gas remaining in the tank?
What is the net force exerted by these two charges on the third charge = 46.5 placed between and at = -1.235 ? Your answer may be positive or negative, depending on direction of the force.
How much work is done by an applied force that moves two charges of +6.8 µC that are initially very far apart to a distance of 5.3 cm apart?
