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.
On earth, 1 kg of mass weighs 9.8 N, and 50 kg of mass weighs 490 N.
Elsewhere, they don't.
.4 kN or 400 Newtons.

12.5. MA=Output Force/Input Force, so MA=5000N/400N=12.5 Note that there isn't a unit because N/N cancels out.
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.
Force=m*g=40 kg*10m/s2=400N Work=F*S=400N*(50*10)cm=200000J PE=total Work done=200000J Power=Work/Time=200000/5=40000Watt
What a strange question. A kilogram weighs a kilogram whatever the substance involved. The volume of the substance will vary though, a kilogram of gold is a cupful but a kilogram of rice is a whole bagful.

Exactly one kilogram is in a kilogram.

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.
A kilogram is a measure of mass therefore a kilogram of lead and a kilogram of feathers have the same mass: one kilogram. They would, however, have different volumes and densities.
