It's a trick question relying on your preconception that feathers are lighter. They of course weigh the same a kg of versus a kg of. Of course it will take a heck of lot more feathers.
Feathers are soft and will not injure anyone, stones will.
As long as they're both on the same planet, every kilogram weighs the same. Put 1 kg of stones and 1 kg of feathers (or 1 kg of smoke or 1 kg of water or 1kg of dust) on opposite ends of a see-saw, and they balance.
1 kg of lead and 1 kg of feathers have the same mass, but they differ significantly in volume. Lead is much denser than feathers, so 1 kg of lead occupies a much smaller volume compared to 1 kg of feathers. Therefore, 1 kg of feathers has a greater volume than 1 kg of lead.
215kg is 33.8567 stones.
68.2 kg is approximately 10.73 stones.
Both 1 kg of feathers and 1 kg of lead have the same mass, which is 1 kilogram. However, feathers have a much lower density than lead, meaning that 1 kg of feathers will occupy a significantly greater volume than 1 kg of lead. Therefore, 1 kg of feathers has a greater volume than 1 kg of lead.
13.88912 stones
60.6 kg is equivalent to 9.53 stones.
39.2 kilograms = 6.17294334 stones
36.85 kilograms = 5.8 stones
Yes, 5 stones is less than 50 kg. One stone is approximately 6.35 kg, so 5 stones is about 31.75 kg. Therefore, 5 stones is significantly less than 50 kg.
Yes. Since they both have a weight of 1kg one cannot be heavier than the other.
