Answer:
1: Chemical Energy
2: Kinetic Energy
3: Electrical Energy
4: Mechanical Energy
Explanation:
1: The energy held in food is called <em>chemical energy. </em>It is a form of <u>potential energy</u> held within chemical bonds between atoms.
2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the <em>kinetic energy of flowing water</em> <u>as it moves downstream.</u>
3: The power for lights and stuff is <em>Electrical</em><em> </em><em>Energy</em><em>,</em> ofc :]
4: The <u>chemical energy in the food</u> gets changed into the <em>mechanical energy</em> of <u>moving muscles.</u>
<u>Hope</u><u> </u><u>this</u><u> </u><u>helps</u><u>!</u><u>!</u><u> </u><u>:</u><u>D</u>
<span>Cocaine Preparations
-Coca leaves --> Coca Paste (60% pure): Not water soluble, so you can't inject it into the bloodstream -- you need an additional chemical step to turn the paste into crystal powder that can be injected or snorted
-Coca --> Cocaine Hydrochloride (99% pure): Doesn't hold up very well to heat, so you can't smoke cocaine hydrochloride
-Cocaine Hydrochloride (99% pure) --> Free-Base Cocaine or Crack Cocaine:
-Reconvert cocaine hydrochloride back to base state by removing hydrochloride from cocaine (that's why it's called free-base cocaine)
-Crack cocaine is a crystallized form, mixture of cocaine and baking soda
-75% pure
-Can be used at lower doses and is much cheaper than cocaine
-Can be smoked</span>
B . to supply energy for splitting the water molecules
The commonly eaten foods produced by plants are root crops, leafy foods, flowers, and seed. Food provides energy and nutrients from organisms such as animals, that cannot trap energy from the sun through hypothesis. Animals called primary consumers eat only plants, humans are called to omnivores eat plants and animals.
Answer:
See below.
Explanation:
A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei. The process is called nucleosynthesis.
Our Sun is currently burning, or fusing, hydrogen to helium. This is the process that occurs during most of a star's lifetime. After the hydrogen in the star's core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point the process releases energy. <u>The formation of elements heavier than iron and nickel requires the input of energy. </u>Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
