I believe the correct answer would be tourism and agriculture. The economy of Central America is primarily based on tourism and agriculture. Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.
Answer:
Thermal (Heat) Energy. Thermal energy is created from the vibration of atoms...
Chemical Energy. Chemical energy is stored in the bonds of atoms and molecules – it is the energy...
Nuclear Energy. Nuclear energy is stored in the nucleus of atoms.

Answer:
A one-step conversion is not sufficient to convert a temperature in the Celcius scale to the Fahrenheit scale.
Explanation:
Hello!
To convert a temperature in the Celcius scale to the Kelvin scale we required just one-step conversion, because we consider that the first scale derives from the second scale.
Celcius scale begins at 0 degrees (0°C), wich coincides with the melting point of the ice, and ends at 100 degrees (100 °C) with the point of water boiling point.
Fahrenheit scale determines that the freezing point of water is located at 32 degrees (32°F) and its boiling point at 212 degrees (212°F). This situation causes a 180 degree interval between the two points.
For this reason, to calculate how many Fahrenheit degrees has a certain temperature expressed in Celcius degrees, we have to multiply the X degrees Celcius (°C) by 1.8, and then add 32 to the previously obtained result.
°F= (X°C x 1.8) + 32

Answer:
The correct answer is: b. intermediate- to low-mass stars (between 0.8x to 8x the mass of our Sun).
Explanation:
Once the hydrogen in the nucleus is finished, the hydrostatic equilibrium is broken, and gravity is able to overcome radiation. This causes the star's core to contract, thus increasing its internal temperature and density. Meanwhile, due to convection, the outer layers expand, so the external temperature decreases. The star increases its external size becoming what we know as the Red Giant.
By increasing the temperature in the core, the necessary conditions are given to begin to fuse Helium and convert it into Carbon. So the core is getting denser and the outer layers of the star expand even more.
The end of our star is marked by the moment when the helium in the nucleus ends. In addition, the outer layers are so far apart that they no longer exert sufficient pressure to compress the core and trigger carbon fusion. In parallel, the star is so large that the outer layers of the star escape the gravity of the star, pushed by radiation. In this way, the interstellar medium of helium, carbon and a little oxygen is enriched. Leaving behind a White Dwarf, the nucleus of the star in which Helium has become Carbon.
The capital of Slovakia is Bratislava.
