If Nation A needs a natural resource that Nation B has a lot of why might Nation A have trouble getting that resource from Nation B?

1. Thermostat.

2. Work out of.

3. Non-renewable.

4. Renewable resources.

5. Conservativism.

6. Non-renewable resources.

7. The reason Nation A might have trouble getting that resource from Nation B could be due to lack of funds (insufficient money) to acquire it, competition for the same resource by other nations, weak bargaining power of Nation A, ability to pay more money by other nations, Nation A and Nation B might be in conflict, tariffs and quotas, etc.

Explanation:

Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.

Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.

Basically, a renewable energy source is sustainable and as such can not be exhausted.

On the other hand, a non-renewable energy refers to an energy source such as fossil fuels that takes a very long time to be created or their creation happened long ago and isn't likely to happen again e.g uranium. Fossil fuels, such as coal, oil, and natural gas, come from deep inside the Earth where they formed over millions of years ago.

Filling the missing words or texts into questions, we have;

1. Set thermostat to automatically turn off heat or air conditioning when buildings are closed to conserve energy.

2. Energy can be used more efficiently getting more work out of each unit of energy.

3. Materials, such as gravel and sand, are technically non-renewable but there is so much of the available that we are unlikely to ever run out.

4. Renewable resources can be regenerated or grow so rapidly that they reappear at the same rate or faster than they are used.

5. When we practice conservatism we make sure resources will be available in the future.

6. Non-renewable resources are resources that cannot be regenerated on a useful timescale.

7. The reason Nation A might have trouble getting that resource from Nation B could be due to lack of funds (insufficient money) to acquire it, competition for the same resource by other nations, weak bargaining power of Nation A, ability to pay more money by other nations, Nation A and Nation B might be in conflict, tariffs and quotas, etc.

it is either c or d and i know for sure it is not a or b
