Question 2 Consider two charges, where one (+3.80nC) is at the origin and the other (-14.4nC) is at the position x=2.86 86 cm. Find the xcoordinate where a proton would experience zero net force. Answer: squareHow often does the sun appear on Venus? A) Every day B) Oncea month C Once every seven years D Only-during summer1. do constellations appear to rotate around Polaris (the North Star)?1-1. Compute the density (in units of m^-3 of an ideal gas under the following PROBLEMS conditions: (a) At 0^circ C and 760Torr pressure (1Torr=1mmHg) . This is called the Loschmidt number. (b) In a vacuum of 10^-3 Torr at room tem perature (20^circ C) . This number is a useful one for the experimentalist to know by heart (10^-3Torr=1micron)10 Multiple Choice 1 point How do football pads help reduce the force of impact?
