Here it is given that an aluminum block having mass equal to 2 kg and it is suspended from estrange and the globe is fully enmes in the water.
00:16
We need to find the oil of the aluminum block.
00:20
The density of aluminum block is 2710 g per meter case.
00:28
So you know that the density equal to the aluminum.
00:31
To marks by volume from this relation we can find the volume of the aluminium.
00:37
So it is mass divided by density of aluminium.
00:43
By substituting the gallows, we can find the rolling of the aluminium block.
00:48
So to greg.
00:49
Divided by the density that is 2710 g per meter per meter.
00:55
So the volume of aluminium block can be calculated as 7 .3a10.
01:01
3x10 can raise to 4 meter 2.
01:07
Then we need to find the buoyant force acting on the floor.
01:12
So the boyan force is the upst force acting on the block can use in the water.
01:19
Since the block is completely in the swindled in the water, so the point can be able as after row w vw g.
01:29
Here, row is the density of water, the responsibility of water.
01:36
Vw is the volume of water displaced.
01:43
Here, the flow is completely ennased in the water...
