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.

Ans 2:

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.

Ans 3:

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.

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

The given statements which summarise the process of digestion are not given in a correct sequence. Arrange them in sequence and select the correct option.
P. Absorption of water
Q. Churning of food and addition of digestive juices
R. Mixing with saliva
S. Complete digestion of food and absorption of nutrients
T. Expulsion of faeces

A R → Q → S → P → T
B R → S → Q → P → T
C R → Q → P → S → T
D R → P → Q → S → T

Ans 4: (Master Answer)

Class : Class 1

The correct answer is A.

When food is taken in the mouth, it is chewed and gets mixed with saliva secreted in the mouth (R). Once swallowed, the food moves through the oesophagus into the stomach where churning and digestion of food with digestive juices occurs (Q). The semi-digested food then moves into the small intestine where complete digestion as well as absorption of nutrients occur (S). From the undigested food, the water is absorbed in the large intestine (P). After this, the undigested food is expelled through the anus in the form of faeces (T).
