Gas makes things buoyant, why ? And what are ways that this could be useful?
ryzh [129]

Answer:

Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.

Gas Buoyancy is useful in the following ways;

• Airships

• Steel ships and

• All floating and flying vessels

Explanation:

Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.

It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

The principle explains the reason why objects float and fly.

So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.

This is where the use of a gas comes into play.

Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.

This is what causes objects to float or fly

How would the experiment need to be modified in order to determine whether the amount of vitamin A absorbed by the body is depen
melomori [17]

Answer:

The experiment should have more different subject groups, with each group consuming a different amount of beta carotene.

Explanation:

When designing an experiment, to determine the effect of the amount of a substance, the experimental design should be done to accommodate more than two experimental group with each group treated with different amount of the substance and also a control group. This will enable the researcher to determine the effect of the different ranges of amount.

In the example, in other to determine if vitamin A is dependent of the amount of beta carotene consumed, there should be more different subject groups, with each group consuming a different amount of beta carotene.

How do older female killer whales help their family​
jeka94

Answer:

Senior mothers are also under pressure to share food with their sons, so that they're able to reproduce as well. It also makes sense for these mothers to assist their sons because as the mothers grow older, they are increasingly related to whales in other, neighboring pods via their sons' calves.
