Answer:
The portion of earth underneath the crust containing the asthenosphere and mesosphere is outer core and inner core .
Explanation:
The outer core of the earth is ball of very hot metals . Its temperature is hot enough to melt all metals into liquid state . This is mainly composed of the melted metals nickel and iron . This has got got temperature between 4000 degrees to 9000 degrees .
Inner core is underneath the outer core ,Here the pressure is too high and this makes the metals squeezed and not even able to move like liquid . They are forced to vibrate just like a solid . This has got a thickness of 800 miles . The pressure here is comparably 3,000,000 times the air pressure at sea level.
R(parallel) = product/ sum
50×30/50+30
1500/80
18,75 ohms
<u>C</u> is the correct answer, because energy cannot be created neither destroy. The energy is changing from chemical to from electric to light, and from light to heat.
If I remember correctly, it is the 3rd answer choice.
