Potential energy due to gravity = Ep = mgh [symbols have their usual meaning ]
Evidently, HALVING the mass will make Ep , HALF its previous value. So, It will be halved.
<span>The earth’s
magnetic field affects the alignment of elements like iron in <span>rocks</span> due to <span>Ferro-magnetization</span>.
This causes the <span>elements</span> to align in <span>a north</span>-south direction. Therefore scientists
have studied this <span>alignment</span> in ancient
rocks, such as in the layers of <span>sedimentary</span>
rocks, and realized that the earth magnetic field has flipped around 200,000 to
300,000 in the last 20 million years. </span>
Answer:
NO.
Explanation:
METALLIC BOND IS ONLY IN METALS.
Since iron is a metal and carbon a non- metal, they cannot form a metallic bond.
