A 10.1 m long, 0.0023 m radius copper wire is stretched between two poles. By landing at the center point of the wire, a bird sends a small pulse out in both directions. The pulses reflect at the ends and arrive back at the birds’ location 2.2 seconds after it landed. Determine the tension (in Newtons) in the wire.
We take the density of copper as 8900 Kg/m3

a, c, d, e are all applying about success strategies.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

not too sure thinking all accelerations are pointed down
