Felipe made a toy boat out of clay, but it kept sinking in water. He changed the boat's design by making it slightly wider than before. Why did Felipe's newly designed boat float on water?
A. He decreased the density by increasing the volume.
B. He decreased the density by decreasing the volume.
C. He increased the density by increasing the volume.
D. He increased the density by decreasing the volume.
Thanks guysss <3
what is the answer i need help plz
The answer would be A.
To understand why Felipe's newly designed boat floated, we need to consider the concept of density. Density is the measure of how much mass is contained within a given volume. Objects with greater density than water will sink, while objects with lower density than water will float.
In this scenario, Felipe's initial clay boat sank in water, indicating that its density was greater than water. He then changed the boat's design by making it slightly wider. By making the boat wider, Felipe effectively increased its volume while keeping the mass (amount of clay) the same.
Now, to find the correct answer, we need to determine how increasing the volume affects the boat's density. The formula for density is density = mass/volume.
Option A suggests that Felipe decreased the density by increasing the volume. This is the correct answer because increasing the volume while keeping the mass constant will lower the density. As a result, the boat became less dense than water and was able to float.
So, the correct answer is:
A. He decreased the density by increasing the volume.
