The equation for the weight of the concrete block under water is given by wcw is equal to wca minus u.
00:13
Here wcw is the weight of the concrete block underwater, wca is the weight of the concrete block in air, and u is the upward thrust acting on the concrete block when it is in the water.
00:30
Let this be equation 1.
00:33
The equation for the weight of the concrete block in air is given by wca is equal to mc in g.
00:46
Here, mc is the mass of the concrete block and g is the acceleration due to gravity.
00:52
Substituting the numerical values in the equation waves, wca is equal to 25 kilogram.
01:00
Into 9 .8 meter per second square which is equal to 245 newton.
01:09
Now the upward thrust acting on the concrete block when it is in the water will be equal to the weight of the water displaced by the concrete block.
01:24
Therefore you is equal to wwd.
01:28
Here wwd is the weight of the water displaced by the concrete block which is equal to mwd into g.
01:39
Here mwd is the mass of the water displaced by the concrete block.
01:45
Now the equation for the mass of the water displaced by the concrete block is given by vwd into row w...
