A large beaker of water is filled to its rim with water. A block of wood is then carefully lowered into the beaker until the block is floating. In this process, some water is pushed over the edge and collects in a tray. The weight of the water in the tray is: a. Greater than the weight of the block.
b. Less than the weight of the block.
c. Equal to the weight of the block.

c. Equal to the weight of the block.

Explanation:

We know that when an object floats , the displaced water by the floating body

has weight equal to the weight of the body . In this condition the upthrust becomes equal to the weight of the body .

In the present case the beaker is full to the brim with water . Then the body was made to float into it . While attaining equilibrium in water , it displaces water whose weight must have been equal to its weight . That liquid got spilled over the edge and collected on the tray .

So water collected on the tray must be equal to the weight of the body floating.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

answer

the arrows to the right of earth should point up.
