Two known forces F1 = 3.75 N at 73.0° below the positive x-axis and F2 = 3.55 N at 33.0° above the negative x-axis are acting on an object. What is the magnitude of the third force F3 so that the acceleration of the object is zero?

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant
