sam threw an object into his backyard pool. the object will float if
a. has more volume than water

b. is more dense than the water

c. has less volume than the water

d. is less dense than the water

Volume doesn't matter in this equation, as air will almost always float on water no matter the volume. So A and C are incorrect. The the object is more dense than water, it will sink because it has enough density to push through the water. But if it is less dense, then the water has enough force to hold it in place because the downward force of the object is less than the force of the water. The correct answer is D.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
