Two blocks of equal mass that are connected by a rigid bar of length 1 move without friction along a given path as shown. The attraction of the earth acts along the negative y-axis. The generalised coordinate is the angle a (corresponding to the single degree of freedom of the system). Find the motion equation using Lagrange differentails?​

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?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.
