Two ethernet cables of the same length are pulled taut at the same tension. cable 2 hasfour times the weight of cable 1. waves travel along the length of the cable 1 at a speedof 8.0 m/s. what is the speed, in m/s, of waves on cable 2?

4 m/s

Explanation:

T = Tension

m = Mass of string

Velocity of wave in string is given by

For first cable

For second cable

The speed of wave in cable two is 4 m/s

d. air pressure decreases as altitude increases.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
