GenaCL600 [577]3 years ago
6 0

Answer:

depends, if you figure out how to use a mammal or a synthetic body system to turn the food into energy and then convert that energy to heat energy only then yes, you could. but i dont think that's a thing that humans have figured out yet(although i believe its completely possible albeit very inefficient seeing as that's taking a hell of alot of energy and turning it into a more dispersible energy as well as an expirable energy source (such as in the matrix, they use humans as batteries and feed each other the remains of the former human batteries.(either that or they repurpose the remains into new humans)) but in any case its not very efficient.

Answer:

Table which was completed correctly is :

B) Answer choice G

Explanation:

Metals : Most of the elements in the periodic comes in the category of metal. They are found in left and middle of periodic table.

<u>List of metals </u>

Alkali : Li , Na , K ,Rb , Cs ,Fr

Alkaline : Be , Mg , Ca , Sr ,Ba ,Ra

Transition : Sc ,Ti ,V ,Cr ,Mn , Fe , Co, Ni Cu , Zn ,Y ,Zr ,Nb ,Mo ,Tc ,Ru , Rh , Pd , Ag , Cd , In , Sn, La ,Hf ,Ta ,W ,Re ,Os ,Ir ,Pt ,Au ,Hg

Non -Metals: Most of the p-block element are non metal. They are present in upper - right corner of the periodic table.

Non - metals : H , He , C ,N , O , F ,P ,S , Cl, Ar , Br , Xe ,At ,Rn,  

Metalloid : They show properties of both the metals and the non - metals.

Also called as semimetals

Metalloid : B ,Si ,Ge ,As ,Sb ,Te ,Po

<u>In table F </u>:

B = metalloid  , N = non metal ( wrong-match) , Ra  = metal ( wrong-match) , He = Non - metal ( wrong-match)

<u>In table G : Correctly matched </u>

I =  Non - metal , Ca = metal , Rb = metal , As = metalloid

<u>In table H</u>:

Ni = metal ( wrong-match) , C = metalloid ( wrong-match) , Mg = metal , Pb = Metal

<u>In table J</u>:

Cu = metal , Sb = Metalloid( wrong-match)  , S = non metal( wrong-match) ,Ne = non metal

How do scientists forecast space weather why?
slava [35]
Well that's a not easy task. <span>The specialized forecasters analyze near-real-time ground- and space-based observations to assess the current state of the solar  environment which includes the areas from the Sun to the Earth and points in between. Space weather forecasters also analyze the pattern of solar activity. </span>
