6. Should we be worried about our trade deficit? Explain why or why not.

Answers

Answer:

A trade deficit is neither inherently entirely good or bad, although very large deficits can negatively impact the economy. A trade deficit can be a sign of a strong economy and, under certain conditions, can lead to stronger economic growth for the deficit-running country in the future.

Explanation:

The most obvious benefit of a trade deficit is that it allows a country to consume more than it produces. In the short run, trade deficits can help nations to avoid shortages of goods and other economic problems. In some countries, trade deficits correct themselves over time.

6. What are the arguments for using real per capita GNI to compare living standards between countries? What weakness does this measure have?

Answers

Answer:

Levels of real per capita GDP are often cited to indicate living standards are higher in one country than another, and, by implication, that some systems of government or sets of government policies are better than others, but this measure of comparative living standards is so flawed as to be practically useless.

The velocity of the rocket is not the same as the speed of the rocket. What is the difference between the velocity of an object and the speed of an object

Answers

The difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.

What is velocity?

Velocity is the time rate of change of displacement.

Speed is the ratio of distance and the time taken to travel that distance.

Thus, the difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.

The U.S. economy grow via trade deficit,  if we import more goods and services.

What is import and export?

When any good or service is  brought in from one country to another is called Import while exports are when goods and services produced in the home country for sale to other countries.

If a country imports more than it exports, it runs a trade deficit. If it imports less than it exports, that creates a trade surplus. When a country has a trade deficit, it must borrow from other countries to pay for the extra imports.

If I increase my mass (by putting in books in the box) shouln't my acceleration go down since they are inversely related to each other (when one goes up, the other goes down and vice versa). My force stayed the same at 10 N, thus only mass and acceleration fluctuated relative to each other.

This Is Chemistry Question, My Laptop Got Lag When I was Posting It :( Explain The Rutherford Atomic Model
Answer Should Be given With Headings!

Answers

Explanation:

that’s hard

Answer:

Rutherford conducted an experiment (α-particles scattering) in order to find the arrangement of electrons and protons in an atom. This experiment led to the discovery of nucleus in an atom.

Explanation:

Rutherford bombarded a thin gold foil (about 0.00004 cm thick) with alpha particles in an evacuated chamber. These particles got scattered and were allowed to to strike on a circular zinc sulphide coated screen. He observed a flash of light on the screen where the alpha particles struck. From this experiment, he made the following conclusions.

Observation 1: Most alpha particles (α-particles) pass straight through the gold foil without any deflection from their original paths.

Conclusion: There is a lot of empty space in the atom.

Observation 2: A few alpha particles were deflected, at small angles and a few at large angles.

Conclusion: There is a small positively charged object at the centre of the atom. He said this because as alpha rays are positively charged it can pass through only negatively charged particles and get deflected by the same charge. He concluded that the small positively charged object present within the atom is called the nucleus.

Observation 3: Very few alpha particles completely rebounded on hitting the gold foil.

Conclusion: The nucleus is dense and hard. It is located at the centre of the atom.

Answers

Answer:

Terms in this set (7)

1. Compare and contrast the fixed, freely floating, and managed float exchangerate systems. What are some advantages and disadvantages of a freely floating exchange rate system versus a fixed exchange rate system?

Under a fixed exchange rate system, the governments attempted to maintain exchange rates within 1% of the initi¬ally set value (slightly widening the bands in 1971). Under a freely floating system, government intervention would be non existent. Under a managed float system, governments will allow exchange rates move according to market forces; however, they will intervene when they believe it is necessary.

A freely floating system may help correct balance-of-trade deficits since the currency will adjust according to market forces. Also, countries are more insulated from problems of foreign countries under a freely floating exchange rate system. However, a disadvantage of freely floating exchange rates is that firms have to manage their exposure to exchange rate risk. Also, floating rates still can often have a significant adverse impact on a country's unemployment or inflation.
