Aloaded tractor-trailer has a mass of 36,000 kg, what is it’s weight?

That depends on WHERE the rig is, because

weight = (mass) x (acceleration of gravity where the object is)  .

-- If the truck is on Mars, then

Weight = (36,000 kg) x (3.71² m/s²) = 133,560N.

-- If the truck is on the moon, then

Weight = (36,000 kg) x (1.62 m/s²) = 58,320N.

-- If the truck is on Earth, then

Weight = (36,000 kg) x (9.81 m/s²) =  353,160N.

It all depends.

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
