3. A ray of light makes an angle of 50° with the surface S1 of the glass slab. Its angle of incidence will be _______.
(A) 50°
(B) 40°
(C) 140°
(D) 0°
Answer: (B) 40°
According to the second law of reflection, Angle of incidence (i) = Angle of Reflection (r).
The angle of a straight line is 180°.
Therefore, 50°+ i + r + 50° = 180°
=> 100°+i+i = 180° (since i=r)
=> 2i = 180°-100°
=> i = 80°÷2
=> i = 40°.
As a result, angle of incidence is 40°.
4. Water expands on reducing its temperature below _______°C.
(A) 0
(B) 4
(C) 8
(D) 12
Answer: (B) 4°C
4°C is the temperature (T) at which liquid water has a minimum volume, at atmospheric pressure. The expansion of water at lower T results from the water molecules arranging themselves to minimize the energy of their interactions.

P2= 60 W and
V=220 V, then
To Find I=?
Formula P=VI
Solution =Total Power (P) = P1 + P2 = 50+60 = 110W
So, if P=VI
I= P/V= 110/220= 0.5 A.
2. Give scientific reason:
In the electric equipment producing heat e.g. iron, electric heater, boiler, toaster etc., an alloy such as Nichrome is used, not pure metals.
Answer: An Alloy such as Nichrome has a higher level of resistivity, so they will get heated easily on the passage of even a small amount of current. Also, electric equipment like iron, electric heater, boiler, toaster and so on work based on the heating effect of electric current.
For this reason, nichrome is used in electric equipment producing heat, such as iron, electric heater, boiler and toaster.
3. A metal ball of mass 5 kg falls from a height of 490 m. How much time will it take to reach the ground? (g = 9.8 m/s2).
Answer: 10 Seconds
u (Initial velocity of the metal ball) = 0
s (displacement travelled by the metal ball) =490m
We know that s= ut + 1/2at2
Replacing the values you get 490= 0 x t + ½ x g x t2
(g is acceleration due to gravity)
Hence, 490= 0 x t + ½ x 9.8 x t2
490= 0 + 4.9 x t2= 4.9t2
t2= 490/4.9= 100
So, t=10.

3. Attempt any five of the following questions: [15]
1. What would be the value of ‘g’ on the surface of the earth if its mass was twice and its radius half of what it is now?
Answer: The formula is given g=GM/R2
In this g is the acceleration due to gravity
M for mass of the earth
R is radius of the earth
G for universal gravitational constant
Now, according to the question
Mass is twice= 2M
Radius is half= R/2
g1 is considered as the new gravity.
When we substitute the formula we get
g1= Gx2M/(R/2)²
g1= 2GM / R2/4
= 8(GM/ R2)
= 8 x g = 8 (9.8) =78.4 m/s2.
2. Write merits of Mendeleev’s periodic table
Answer: Mendeleev’s periodic table demonstrates the following merits:
1. Mendeleev classified the 63 elements known at the time.
2. Atomic masses of some elements were revised, so as to give them proper place in the
periodic table, in accordance with their properties.
3. Mendeleev kept vacant places in the periodic table for elements not discovered till
then. Three of these unknown elements were given the names eka-boron, eka-aluminium
and eka-silicon from the known neighbours and their atomic masses were indicated as
44, 68 and 72, respectively. Their properties were also predicted.
4. Even though there was no place reserved for noble gases in Mendeleev’s original periodic
table, when noble gases such as helium, neon and argon were discovered towards the end of
19th century, Mendeleev created the ‘zero’ group without disturbing the original periodic table in which the noble gases were fitted very well.

(iii) Silver Nitrate and Sodium Chloride are the reactants or products used in the above reaction.
4. Explain the following temperature vs. time graph:
Answer: See the graph given, which represents the changes occurring when a mixture of ice and water is heated. In this graph, the line AB signifies the conversion of ice into the water at a constant temperature. Heated ice melts at 0°C and converts to water even as it maintains the constant temperature at 0°C. This constant temperature is also known as the melting point of ice. Meanwhile, line BC represents the temperature rising from 0°C to 100°C, on further heating. At 100°C water converts to steam, and this is called a boiling point of water. After that, even on heating, the temperature of the water does not rise. Line CD represents this state when there is no change in temperature.

7. What is meant by space debris? Why is there a need to manage the debris?
Answer: In addition to the artificial satellite, there are some other objects revolving around the
earth. These objects include, non-functional satellites, parts of the launcher detached during launching and debris generated due to collision of satellite with other satellites or any other object in the Space. Meanwhile, as per an estimation made in 2016, there are about 2 crore pieces of length more than 1 cm, revolving around the earth. All these are nothing but the debris in space. This debris can be harmful to the artificial satellites. It can collide with these satellites or space crafts and damage them. This debris is increasing day by day. Soon, it will be difficult to launch new space crafts. It is, therefore, very essential to manage the debris.

left to right, within a period?
Answer: (i) According to the decreasing order of atomic radii:
Li > Be > B > C > N > O.
(ii) The given elements belong to Period 2.
(iii) You will find that the atomic radius goes on decreasing while going from left to right, within a period. The reason behind this is as follows. While going from left to right, within a period, the atomic number increases one by one, meaning the positive charge on the nucleus increases by one unit at a time. However, the additional electron gets added to the same outermost shell. Due to the increased nuclear charge the electrons are pulled towards the nucleus to a greater extent and thereby the size of the atom decreases.
(iv) In these elements, Lithium has the biggest atom and Oxygen has the smallest atom.
(v) You will find that the atomic radius goes on decreasing while going from left to right within a period.
