Answer:
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.

Answer:
m=F/a
= 44/4
= 11 m

Just use the formula F=ma
Answer:
acceleration = 4.21 [m/s^2]
Explanation:
Newton's second law of motion tells us if that the sum of forces on a body is not equal to zero, this body will move with a constant acceleration.
This we can explain in the following equation:
Replacing the values we have.
