E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.

Ans 2:

Class : Class 8
E(energy)=m(mass)*c(speed of light in vacuum)2.... speed of light in vacuum=3.00 x 108(10x10x10x10x10x10x10x10).... It means that there is much more energy stored inside the nucleus of an atom than in its valence electrons. The energy released from splitting an atom is much higher than that of breaking electron bonds.

in simple terms "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.

The correct answer is D.

The given graph shows that the temperature of water is not increasing with time from period ‘X’ to ‘Y’, which shows that drum. water has attained its boiling point (100°C). On reaching boiling point, the temperature of water does not increase further and water converts into vapour.

Shruti took a white carnation flower and split its stalk halfway along the length and arranged a setup as shown in the given figure. After some time, she observed that half of the petals turned blue and half turned red. A section through stem also showed blue and red coloured areas.
What can she infer from this experiment?


A Stem conducts water to all plant parts.
B Stem has localised structures for conduction of water.
C Stem conducts solutes alongwith water.
D All of these
