Kgs is a unit of mass while Newton is a unit of force, should only be compared under specific circumstances. But for normal earth conditions you get 9.81 N/kg, so 400 N is a bit below 40.7747196738 Kg.
The net force is 200N to the left (400N - 200N = 200N).
The work done on the couch is given by the formula: Work = Force x Distance. In this case, the work done is 400N x 4m = 1600 J (joules).
The mechanical advantage of the jack is calculated by dividing the load force (5000N) by the effort force (400N). In this case, the mechanical advantage of the jack is 12.5, meaning that for every 1 unit of effort applied, the jack is able to lift 12.5 units of load.
A kilogram is bigger than a centigram. There are 100,000 centigrams in a kilogram.
The formula for tension is T = mg +/- ma. Thie tension on the rope is still only 400 N, regardless if one person is pulling or two people are pulling.
The net force is 200N to the left (400N - 200N = 200N).

No. A kilogram is a kilogram is a kilogram. On the other hand, a kilogram of sand will most likely be a different size than a kilogram of gravel. We are told by the question though that they both weigh one kilogram, so they are the same weight.

The abbreviation of Kilogram is 'kg'.
Heck, one killogram, I bro you, is a kilogram, dummy.
