The ship's deadweight is the seventh power n of 5x10, and its maximum carrying capacity is the eighth power n of 1.3x10. When it is fully loaded, its displacement is () t, and its buoyancy is () n

The ship's deadweight is the seventh power n of 5x10, and its maximum carrying capacity is the eighth power n of 1.3x10. When it is fully loaded, its displacement is () t, and its buoyancy is () n

The displacement of the ship is set at x tons,
When the ship is fully loaded, it can carry cargo + ship weight = ship buoyancy;
1.3X10^8N+5x10^7N=X*1000*10N/kg;
It can be found that x = 1;
F = x * 1000 * 10N / kg = 1.8x10 ^ 8

When two identical objects are immersed in alcohol and water, the buoyancy in alcohol is 5N, and the buoyancy in water is 6N. Find its density, gravity and state

Because the buoyancy in water is greater than that in alcohol, so: 1) if they all float or float in alcohol, then buoyancy = gravity, buoyancy should be the same. It is impossible to float all or float in alcohol. 2) if they all sink to the bottom, then buoyancy f = P liquid * VG, buoyancy ratio = density ratio = 0.8:1 = 5:6.25, not 5

There is a small ball floating on the water, half of which is out of the water. When alcohol is added to the water, the buoyancy of the small ball will be reduced
1 unchanged 2 larger 3 smaller 4 unable to judge

The ball floats all the time, so the resultant force is zero, that is, gravity equals buoyancy
