Answer:
There shall be a LABEL
Explanation:
The label is to enable the maintenance personal or the user to identify the individual conductor from each other during removal and installation or when maintenance task is being carried out on the system. This is to avoid the users of the system form plugging the conductor incorrectly.
For example, if there are four conductors label A, B, C, and D there will be four connection point label same way. By this, the user will not plug conductor A to plug B.
Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.
First Car : <em>0.5 * 2000kg * 3m/s^2 = 10.24 KJ</em>
Second Car :<em> 0.5 * 2000kg * 2m/s^2 = 4 KJ</em>
Leftover Energy : <em>10.24 KJ - 4 KJ = 6.24 KJ
</em>
Movement of BOTH cars :<em /><em>
6.24 = 4000kg * v^2
</em>v = √(6.24 / 4000) =0.04 m/s = 4 cm/s
