friction is the resistance that one surface or object encounters when moving over another. Due to gravity pulling everything down things need to friction in order to move
i hope this helps :/
2/5 = .4
.4*100= 40%

Answer:
The resistance must be 6.67
Solution:
Resistance, 
Resistance, 
For the current to be the same when the switch is open or closed, the resistances must be connected in parallel as current is distributed in parallel with the same voltage across the circuit:
Thus in parallel:



There's the fan over the stove and in the microwave oven, the dispose-all under the sink, the blender, the washer, the dryer, vacuum cleaner, hair dryer, and there are many in a computer.
Hope this helps!
