A phone cord is 3.26 m long. The cord has
a mass of 0.224 kg. A transverse wave pulse
is produced by plucking one end of the taut
cord. The pulse makes four trips down and
back along the cord in 0.865 s.
What is the tension in the cord?
Answer in units of N

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
