The volume of buoyancy airship is 2000m cubic meters, the weight is 4900n, and the air density is 1.2 Grade 8 Volume 1 Science Chapter 1 buoyancy help The volume of the airship is 2000m cubic meters, the dead weight is 4900n, and the air density is 1.29kg/cubic meter. How much buoyancy does the airship suffer in the air?

The volume of buoyancy airship is 2000m cubic meters, the weight is 4900n, and the air density is 1.2 Grade 8 Volume 1 Science Chapter 1 buoyancy help The volume of the airship is 2000m cubic meters, the dead weight is 4900n, and the air density is 1.29kg/cubic meter. How much buoyancy does the airship suffer in the air?

F floating = V row x P row x g (V is volume, P is density, g = 10 N / kg), airship is in the air, so V row = V boat, so f floating = 2000m ^ 3x1.29kg/m ^ 3x10 n / kg = 25800n,
[airship deadweight 4900n, then its maximum deadweight is (25800-4900) / 10 = 2090kg;] (expansion)
