Rope (initially vertical) va flexible, uniform rope of mass m and length l is initially held motionless over frictionless ice, with one end just touching the ice. at the bottom of the rope is a very small, frictionless ramp that causes the rope to end up sliding horizontally on the ice with velocity v. what is the magnitude of v?

What are similarities and differences of reflection, refraction, diffraction and absorption?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
