May i know what is it for?
<h3>
Answer: A) Solar</h3>
=========================================================
Explanation:
The sources of wind, hydro, and fossil fuels all use a turbine. So we can rule out choices B,C, and D.
A turbine is basically a wheel that spins to generate motion energy into electrical energy. Think of it like one of those stationary bicycles and the bike powers up a nearby lamp (the faster you pedal, the brighter the bulb gets). Another example that's similar to a turbine would be those flashlights where you can rotate a crank to have the light come on (which is useful for when the batteries are completely dead). The windmill blades act as a giant turbine that the wind spins around. Hydroelectric turbines are spun by the falling water. Fossil fuels are burned to create very hot steam which then powers a turbine. Even nuclear power uses turbines as well. With fossil fuels and nuclear energy, the idea is to heat up a vat of water and then turn that intensely hot steam into electrical energy through a turbine.
With solar panels however, the electrical energy is converted through a process of sunlight interacting with the solar cells that <u>doesn't require a turbine</u>. This explains why you can use solar panels to power up devices such as phones or laptops without having any moving parts. All you need is a flat set of solar panels.
There is a slight variation of solar power known as "concentrated solar power", aka "concentrated solar thermal", where solar panels are not used. Instead, a vast array of mirrors are set up to aim the suns rays at a very specific narrow area. Think of it like a magnifying glass to focus the suns rays. The place where the narrow beam hits has a very high temperature. This high temperature heats up water to turn to steam, and the process from here is effectively the same as fossil fuels or nuclear energy. So that means turbines are involved with concentrated solar power. I'm assuming your teacher is specifically referring to solar panels when they mentioned choice A.
Answer:
The correct answer is - All of the above
Explanation:
Food is produced at every part of the earth as it may be found even in the parts that are darkest at night or at the part of ocean. Communication between mates can be done by signals that may sent to show interest in mating, Camouflage is the way to escape or hide by use of the light that may momentarily distract predators as it can camouflage the underbelly of the fish by lighting it up the same color of as the sea surface to make it invisible.
Answer:
The complete question is
Freud assumed that what was male was "normal" and that females were "inferior, castrated males."
Our answer is
True
Explanation:
Freud proposes that the boy and the girl begin, pre-Oedipally, having equal emotional position, attracted to the mother, and that the little girl is also a little man as the little girls are not distinct or sexually differentiated.
Freud stands on the concept of a single, masculine, libido: as its initial object is the mother and it's linked to masculinity and activity. He believes that there is no sexual classification or separation at the libido's most primordial phase. He further stated that a genital organization occurs after the Oedipal Complex which was derived in relation to castration as it is the final stage in sexual development. Thus, Freud stands on both children at infancy being ‘little men,’ with their desire construed via the process of a singular masculine libido.
Freud is of the belief that women are the inferior ‘castrated,’ males (lacking of a penis) and men are the normal one (who have penis).
The number used. the answer should be the same, either both 10 or both 100 or something along those lines. it doesn’t give you an accurate or fair comparison between the two.
