Foaung Log
A log was cut from a tree and put in water. The log floated on its side so that half the log was above the water surface
Another log was cut from the same tree. This log was twice as long and twice as wide. How does the larger log float
compared with the smaller log?
1. Choose the best answer.

• More than half of the larger log floats above the water surface.
Half of the larger log floats above the water surface
Less than half of the larger log floats above the water surface

The larger log floats the same as the smaller one, so the correct answer is that half of the larger log floats above the water surface (second option).

Explanation:

An object's ability to float when in water depends on its density, so two objects with different densities will float differently. Density is the relationship between the mass and volume of a material.

Objects with low density float more than denser objects, regardless of the amount of material.

Since the trunks come from the same tree, it can be assumed that they both have the same density, so they will float the same way, regardless of the size of each one.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
