A radio-controlled car increases its kinetic energy from 4 j to 12 j over a distance of 2 m. what was the average net force on t
just olya [345]
The answer to this is easy once you look at the units for Joules. 1 Joule = 1 N.m (Newton.meter). The 'Newton' is the units of force that we are trying to find, and we know the meters is 2, from the question. So you have an 8Joule or 8N.m energy difference over 2 meters.

well if we know the meters, then the real question is written as:
8N.m = ?N x 2m
so just solve for N;
N = 8N.m / 2m = 4
So F = 4N

Why are the wires twisted around each other in twisted pair cable?
Goryan [66]

The wires are twisted around each other in a twisted pair cable for the purpose of blocking off any external electromagnetic interference.

A twisted-pair cable is a form of cable system used for telecom services as well as most current wired networks. Twisted pairs are composed of two insulated copper wires that are been twisted together. The circuit is formed by a twisted pair of wires that may carry data. These pairs are twisted to prevent interference or noise caused by neighboring pairs.
