It is false scientist don't need to repeat an experiment
Answer:<u> Option D
</u>
Solar panels contain a very expensive element, i.e. silicon. This element is able to convert the solar energy into electric energy. The cost of the solar panel gets expensive because of this rare element. It is found in limited areas of the world. That’s why option D is correct. Coal is not used in solar panel, so option B is incorrect. Neither is wind energy, so option A is also incorrect. Water is also not used for exploiting solar energy, which makes option C a wrong answer.
4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.
Hence, the given statement is true.
5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.
Hence, the given statement is true.
Answer:
in the epicenter
Explanation:
In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.
Answer:
BitTorrent protocol
Explanation:
BitTorrent is a system that allows the sharing of almost any file over the internet, being mainly used for the distribution of videos, music and software. It is quite popular because it is an easy tool to use and at the same time very efficient.
BitTorrent itself is actually a data sharing protocol and not a centralized system. There is no server providing the data, but a standard of communication between multiple computers that allows files to be located, distributed and retrieved by all. This protocol is very much used for pirate sharing of music and movies.
