Which is one characteristic of hurricanes?
siniylev [52]

Given the following choices, determine which best suits as a characteristic of a hurricane.

Answer Choices:

A. Hurricanes occur mostly inland

B. Hurricanes create widespread damage

C. Hurricanes can only last for a short amount of time

D. Hurricanes gain strength after passing overland

Best Answer: B. Hurricanes can create widespread damage.

Reason: A would not be correct since it is more of a variable, due to the fact that hurricanes usually begin near the coastlines, hurricanes are in fact capable of moving inland for atleast 100 miles before it dies down to a tropical storm or depression.

C is not correct since hurricanes can last up to a whole week which is approximately 168 hours.

D is not correct since it is another variable in which hurricanes can decrease in strength if it comes into contact with cool and dry air which is the opposite of warm and moist which it needs in order to occur.

Therefore, the best choice is B. Hurricanes can create widespread damage, hurricanes can unleash a staggering arsenal of mother nature's strength and the most damage a hurricane has caused can go up to 125 billion USD in damages.

mezya [45]

Answer:

Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>

Explanation:

The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).

This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.

In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant?
Flura [38]

The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.

 <span>P1V1/ T1 = P2V2 / T2</span>

 <span>Assume the volume decrease by half; V2 = V1/2</span>

 <span>P1V1/ T1 = P2V1 /2 T2</span>

 <span>Cancelling terms,</span>

 <span>1/T1 = 1/2 T2</span>

T2 = T1/2

 <span>Thus, the temperature decreased.</span>
