Abucket of mass 2.00 kg is whirled in a vertical circle of radius 1.20 m . at the lowest point of its motion the tension in the rope supporting the bucket is 27.0 n.
a) find the speed of the bucket (hint: draw a free-body diagram of the bucket at the bottom of the motion.
b) how fast must the bucket move at the top of the circle so that the rope does not go slack? (hint: draw a free-body diagram of the bucket at the top of the motion.)

What is part of a line has one endpoint and continues in one direction?

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?

Asign is hung between two cables as illustrated below. if the sign weighs 350 n, what is the tension (in n) in each cable?
