a weight equal to the upthrust of the water
In a micro gravity, if the mass of each are equal they would 'weigh' the same.
Because the density of the cotton is less than that of the water. It weighs less.
Oil is slightly less dense than water and a litre of water weighs a kilogram. It would be less than a kilogram, but by how much depends on the type of oil.
it basicly depends on the quantity: if there is more water and less bricks then the water weighs more if there are more bricks than water then the bricks weigh more if the bricks and water are in equal amount, then if the water is really dense it may weigh more... it varies
false
No it Does Not Vinegar mixes with Water meaning that it weighs less or about the same
You haven't said "more or less" than what. He weighs more than a beach ball and less than a manatee. Everybody weighs less in water than they do out of it. But every person weighs more than some other people and less that some other other people, whether any of them are in or out of the water.
A gallon of water weighs about 8.3 pounds. The answer is ice. Ice weighs around 12.45 pounds, which is 50% more than a gallon of water, but when it melts and its weight is reduced by 50%, it weighs around 6.225 pounds, which is less than a gallon of water.
An object that weighs 0.85 grams or ml will float in tap water because the density of tap water is about 1 g/ml. The object is less dense than the water, so it will displace water equal to its weight and float.
yes cuz oil weighs less than water
No, cold water weighs more (for a given volume) than hot water. This is why there is a thermocline in bodies of water. But when water freezes, the solid form weighs even less (for a given volume), this is why ice floats.
