You are asked to add ballast to a helium-filled
balloon until it will float in the centre of the
room.
(a) What could you use as ballast?
(b) What happens if you add or remove some
of this ballast?

Answers

Answer 1

Since helium is lighter and less dense than the air around it, it exerts a buoyant force in helium balloons. The lifting force in hot air balloons is created by lowering the density of the air inside the envelope and altering its temperature.

What is the balloon's buoyant force?

Air has a higher density than helium. There are 0.0114 pounds of helium per cubic foot. The air pushes up with a force equal to the weight of the air the helium displaced, or 0.0807 pounds, while gravity pulls the helium down with a force of 0.0114 pounds for a one-cubic-foot balloon.

When a balloon filled with helium rises, how does its buoyancy change?

Since the inflatable would rise whenever delivered, this light power should be more noteworthy than the heaviness of the helium-filled swell. To put it another way, the helium-filled balloon has a lower density than the air it moves because its weight is lower than the volume of air it moves.

what is the difference in between ghettos and concentration camps

Answers

A difference between ghettos and concentration camps was that ghettos were often located in the cities and urban areas while the concentration camps were not.

What were the ghettos and the concentration camps?

After the Nazis began World War II, they began to capture Jews all over Europe. They would then set up ghettos in the cities where Jews would be forced to live in squalor. These ghettos would be separated from the rest of the city so that the Jews could be separated from the general population. In these ghettos, Jews were further oppressed by the Germans with murder and assault being the order of the day.

Concentration camps on the other hand, were set up away from urban areas because the Nazis did not want the general population to find out how badly they treated the Jews there. In these concentration camps, Jews would be worked to death or even just killed systematically.

Answers

A lower interest rate can mean paying less in interest over time, so it's worthwhile to inquire. You may even be able to qualify for a credit card with a 0% APR for a limited time, though you'll typically need good or excellent credit to do so.

What is a good interest rate for a credit card?

A good credit card APR is anything less than 14% if you have good credit. If you have excellent credit, you may be able to qualify for a lower rate, such as 10%. If you have poor credit, your best credit card APR may be higher than 20%.

Lowering interest rates reduces the cost of borrowing money. This boosts consumer and business spending and investment, as well as asset prices. Lowering rates, on the other hand, can cause issues such as inflation and liquidity traps, which undermine the effectiveness of low rates.

Relationship between recession and unemployment-

Recession and unemployment seem to go hand-in-hand. For many individuals, unemployment describes their primary experience of a recession, as they are laid off or unable to find work. The two concepts are so closely linked in people’s minds, that many people feel some confusion about the relationship between them. Does a recession cause unemployment? Or does widespread unemployment cause a recession? Or are the two actually not correlated except in the imagination?

The simplest answer is that recessions cause unemployment. At the same time, once people become unemployed, they have less money to spend on goods and services. So, a recession in a certain sector of the economy can cause unemployment, and that unemployment can cause a recession in a different part of the economy. While the simple answer may be that recessions cause unemployment, the relationship between recessions and unemployment is complex.
