Which exerts more pressure on the ground an empty cardboard box or the same piece of carboard after it has been flatened for recycling and why?
The empty cardboard box exerts more pressure on the ground because its weight is concentrated on the bottom. When the cardboard is flattened for recycling, its weight is distributed over a larger area, reducing the pressure exerted on the ground.
Can cardboard float?
Cardboard can float in water depending on its thickness and density. If the cardboard is thick and has low density, it is more likely to float. However, if it is thin and has high density, it may sink.
Why does cardboard float?
Cardboard floats because it is less dense than water. When placed in water, the upward buoyant force is greater than the downward force of gravity, causing the cardboard to float.
How much does a cardboard box weigh?
The weight of a cardboard box can vary depending on the size and thickness of the box. On average, a small cardboard box may weigh around 0.2-0.5 pounds, while a larger box can weigh 1-2 pounds.
Can an object made of cardboard float?
Yes, depending on its size and weight, an object made of cardboard can float in water. The cardboard's buoyancy is based on its density, shape, and ability to displace water. However, wet cardboard loses its structural integrity and buoyancy, causing it to sink.
