Answer:

Option B.

Step-by-step explanation:

In a circuit shown in the figure two diodes are attached in which arrow shows the direction of current allowed by the diodes.

When key S1 is closed current flows from electric source to S1 then bulb. Afterwards if key S3 is closed current will pass through S3 and diode. Therefore to light the bulb circuit will be a closed circuit if S1 and S3 both are closed.

Therefore option B. is the correct answer.

The answer is b because from s1 it goes to s3 and then it can go through the center of s2 and s3 and resume its curcuit

sammy [17]

A line parallel to the y-axis that passes through (77,88) is x = 77.  There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.

Do you think that it is possible to obtain a good indication of the precise degree of protection accorded by a country to its im
GrogVix [38]

Answer:

The answer is below

Step-by-step explanation:

First we have that free trade refers to the movement of goods, services, capital and knowledge from one place to another. But in reality, free trade does not exist since there are many tariffs and non-tariff barriers.

However,

- Tariff barriers are taxes imposed on imports into a country according to quantity or quantity. Tariff barriers increase the price of imports in the country, which affects the demand for goods and services. Countries agree to lower these tariff barriers, which make trade reasonable for countries that sign agreements.

- Non-tariff barriers are barriers that do not directly affect import prices. It does not impose a tax directly on imports. It tries to reduce imports by using barriers other than taxes.

Therefore countries try to protect their domestic industries using various tariff and non-tariff barriers. The amount of the barriers cannot be precisely decided, since the barriers are not only to protect national industries, but some barriers are imposed to avoid the economic and political monopoly of a foreign country in the national country.

Government actions:

The government applies various health and safety regulations to domestic and foreign products, since consumers in the country must be protected against any impurities. Still, these restrictions are also more than required, leading to protectionism.

The government uses various tariff and non-tariff barriers not only to protect national industries but also for various social, economic, and political reasons.

Therefore, it is difficult to establish tariff and non-tariff barriers in a country accurately.
