Answer:

C. The balloon will rise in the air.

Explanation:

It is already established that helium is lighter than ordinary air. By gravity, the heavier things will drop down, while the lighter will push itself upwards. If a balloon is filled with helium, then the oxygen would be pushed downwards as the helium pushes the balloon higher.

bulgar [2K]

Answer:

Emily's opportunity cost of producing 1 milkshake is 1 ice cream sundae.

Ben's opportunity cost of producing 1 milkshake is​ 0.5 ice cream sundae.

Explanation:

Both Emily and Ben own an ice cream parlor.

In an hour Emily can produce 40 milkshakes or 40 ice cream sundaes.

Emily's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{40}{40}

= 1 ice cream sundae

In an hour Ben can produce 20 milkshakes or 10 ice cream sundaes.

Ben's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{20}{10}

= 0.5 ice cream sundae

We see that Ben has a lower opportunity cost of producing milkshake, so we can say that he has a comparative advantage in producing milkshake.
