Jackson is designing a new heater, and he wants to experiment with different thermally conductive materials. which of these materials would be useful in conducting heat? a. cork b. wood c. soil d. aluminum

Step-by-step explanation:

Conductive materials refer to those materials which have lower resistance to the movement of electric charges, the higher this resistance, higher the conductivity, because electrons would move faster.

Think about friction, conductive materials have low friction for electrons to move, that's why the can easily conduct electricity, like metals.

Now, among the options, aluminum is a metal, which means it can easily conduct electric currents, thanks to its internal structure, electrons can travel faster than inside wood, cork or soil.

Therefore, the right answer is D. aluminum.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
