The density of Iron is a property of the Iron itself, and not related to how much you have of it.
yes
No
No.
Sincerely, it is quite possible.
It depends, what type of wood as different types have different masses :)
-1
2 kg is more.
2 what? grams, kilograms? Be more precise you dummy
1 kg plus 1 kg.
1/5 kg
Not if they're in the same place, or simply on the same planet. But if the 1 kg is on the Earth and the 2 kg is on the moon, then the force of gravity on the 1 kg is 9.8 newtons (2.205 pounds), and the force of gravity on the 2 kg is only 3.2 newtons (0.730 pound). And if the 1 kg is on ANY planet, and the 2 kg is in space, then the force of gravity on the 1 kg is something, and the force of gravity on the 2 kg is approximately zero.
1 kg = 1000 grams 1 quarter of kg = 1000/4 grams = 250 grams 2 kgs + 1/4 kg = 1000 x 2 + 250 = 2250 grams
