Answer:
The answer is letter A. Diamond
Explanation:
The diamond is a crystalline form of carbon, with a cubic structure, of the sp³ type, that is, each carbon atom of the structure is linked to four other carbon atoms, forming a tetrahedral geometry.
E = m c^2
E is energy in joule, m is mass in Kg and c ....speed of light (as you mention)
Substituting your values in the equation
E = ( 5.63 x 10-7kg ) (3*10?^8) ^2 = 5.067 *10 ^10 J
<u>Answer:</u>
OPTION(c)
Water when it warms above 4 °C Its density decreases.
<u>Explanation:
</u>
Since, temperature and density of water are inversely proportional to each other i.e when the temperature of water increases ,the density of the same hence decreases and vice versa.
At 4°C water has attained its most stable state and so has the maximum density. As the temperature warms up above 4°C the molecules of water begin to expand and hence density decreases with the increase in temperatures and contracts with the decrease in temperature
