5206.	Read the following passage carefully.1. What would we do without humor? How would we enjoy talks with others if we did not use humor to invite a smile or a laugh? And how would we manage the times when we feel sad and alone? 2. With humor we lighten up each day, and we find common ground with others. We build healthy relationships with others by knowing what to say and to do that helps, and what hinders, a conversation. Humor often takes us to the edge of uncertainty when we exaggerate, or tease others to make our point. When humor is successful, we build trust and cooperation. We discover that we are not alone, we learn to accept our mistakes, and we look for the good in others and in our selves. Most importantly, we create common ground. However, when we lose our sense of humor, we often get critical or defensive, and, we often get critical of ourselves for what was said, and how it was said. . 3. Humor is an essential skill needed to communicate well with others. A few well chosen words get the attention of others and make a serious point without their getting defensive. Whether we prefer to be the centre of attention or shy and quiet, humor can be adjusted to suit our personality. 4. The challenge for everyone is to become more aware of how to add humor, and when to avoid it. Too much humor, like too much spice often annoys others. Humor that is perceived as insensitive often leads others to shut down, or become argumentative. But when we each maintain our sense of humor, we look for the good in others and in ourselves. To ensure that our humor is welcomed by others, we need to combine our humor with speaking clearly and listening effectively. 5. Have you ever noticed that successful individuals often use self-deprecating humor to humble themselves, without putting themselves down? These individuals understand that every person has strengths and weaknesses and that selfdeprecating humor invites others to feel more confident and equal. Having humor helps us keep our perspective, stay responsive to others, and resolve differences. Do you already have some things that you say to diffuse tension? Words like “At times like this, my uncle used to say…” can help the conversation to become less confrontational. 6. If you can’t think of a humorous comment that will be helpful, you can try looking for clarification by mirroring back their words and clarifying their point. Assume that there is always something that you can find to appreciate when you are looking for common ground. Focus on preventing an argument. Remember, humor is often not the best choice to handle conflict. 7. Opportunities to add a touch of humor happen all of the time. In December when I visited my friend Tim in the hospital, I came wearing antlers from the Dollar Store. And when I was accepted into the graduate program at University of Waterloo, I wrote my acceptance letter as a poem. In each situation my small change from the everyday stirred others to smile, and expect positive conversations in the future. 8. Much of our humor comes from reconnecting to our playful inner child. For many of us, it only takes a playful voice tone, wearing a funny hat, or holding a stuffed toy to get started. Take a risk. Add a bit more humor, and do it in the way that is right for you. (By Leslie Rose Seminars)I. Answer the following questions as briefly as possible.(a) What is the challenge for everyone regarding humor? (b) How can one ensure that humor is welcomed by others?

5217.	Define the following terms:ElectrophoresisAdsorptionShape selective catalysis.
Answer» The movement of colloidal particles towards oppositely charged electrode in an electric field is called electrophoresis. Adsorption: The phenomenon of attracting and retaining the molecules of a substance on the surface of a liquid or solid leading to a higher concentration on the surface in comparison to the inner bulk is called adsorption. Shape-selective catalysis: The catalysis which depends upon the structure (size) of the catalyst and molecular size of a reactant and product molecule is called shape selective catalysis e.g. zeolite.

Distinguish between nuclear fission and fusion.

Answer»

	Nuclear Fission	Nuclear Fusion
Definition	Fission is the splitting of a large atom into two or more smaller ones.	Fusion is the fusing of two or more lighter atoms into a larger one.
Natural occurrence of the process	Fission reaction does not normally occur in nature.	Fusion occurs in stars, such as the sun.
Byproducts of the reaction	Fission produces many highly radioactive particles.	Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that.
Conditions	Critical mass of the substance and high-speed neutrons are required.	High density, high temperature environment is required.
Energy Requirement	Takes little energy to split two atoms in a fission reaction.	Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
Energy Released	The energy released by fission is a million times greater than that released in chemical reactions, but lower than the energy released by nuclear fusion.	The energy released by fusion is three to four times greater than the energy released by fission
Nuclear weapon	One class of nuclear weapon is a fission bomb, also known as an atomic bomb or atom bomb.	One class of nuclear weapon is the hydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction.
Energy production	Fission is used in nuclear power plants.	Fusion is an experimental technology for producing power.
Fuel	Uranium is the primary fuel used in power plants.	Hydrogen isotopes (Deuterium and Tritium) are the primary fuel used in experimental fusion power plants.

Answer»

The correct option is (D) -F.

Force along AB is zero as magnetic field is along AB.

The net force on a current carrying loop is always zero.

F_net = F on AB → +F on BC→+F

Hence on AC,

⟹0 = 0 + F+ (F on AC)

Hence, F on AC is −F.

Light above the threshold frequency will eject an electron with some kinetic energy. These trends are known as the photoelectric effect.

⇒ cb = da ⇒ (c, d) R (a, b)

∴ R is symmetric

Let (a, b) R (c,d),d and (c, d) R (e, f) for a, b, c, d, e, f ∈ N

Then ad = bc and cf = de

⇒ a d c f = b c d e or af = be ⇒ (a, b) R (e, f)

∴ R is transitive

So R is an equivalence Relation

What is the value of (cos2 67° – sin2 23°)?

Answer»

Cos² 67° - sin² 23°

= sin² (90°- 67° ) - sin² 23°

Answer»

Given d = -4 and a₇= 4

We know that n^th terrn of A.P is

a_{n =}a+(n-1) d

a₇ = a + (7 -1)d [ n = 7 ]

4 = a + 6 (-4)

Answer» 3x + 2y - 7 = 0 .......(i) 4x + y - 6 = 0 ..........(ii) From eqn (ii) 4x + y - 6 = 0 y = 6 - 4x Value of y put in eqn. (i) 3x + 2y - 7= 0 3x + 2(6- 4x) - 7 = 0 3x + 12 - 8x - 7 = 0 5 - 5x = 0 5x = 5 x = 1 Substitute the value of x in eq (ii) to get value of y, 4x + y - 6 = 0 4(1) + y - 6 = 0 4 + y - 6 = 0 y - 2 = 0 y = 2 Hence, values of x and y are 1 and 2 respectively.

Solve the following pair of linear equations by substitution method :3x + 2y - 7 = 04x + y - 6 = 0

Answer»

3x + 2y - 7 = 0 .......(i)

4x + y - 6 = 0 ..........(ii)

From eqn (ii)

4x + y - 6 = 0

y = 6 - 4x

Value of y put in eqn. (i)

3x + 2y - 7= 0

3x + 2(6- 4x) - 7 = 0

3x + 12 - 8x - 7 = 0

5 - 5x = 0

5x = 5

x = 1

Substitute the value of x in eq (ii) to get value of y,

4x + y - 6 = 0

4(1) + y - 6 = 0

4 + y - 6 = 0

y - 2 = 0

y = 2

Hence, values of x and y are 1 and 2 respectively.

A number is chosen at random from the numbers -3, -2, -1, 0,7,2, 3. What will be the probability that square of this number is less than or equal to 1 ?

Answer»

Favourable outcomes are -1, 0, 1

Required probability = 3/7

Detailed Answer:

S = {-3, -2, -1, 0, 1.,2,3}

Let E be the event of getting a number whose square is less than or equal to 1.

So, E = {-1,1,0)

P(E) = 3/7

Hence, the probability of getting a number whose square is less than or equal to 1 is 3/7.

If x + y + z = 1, xy + yz + zx = – 1 and xyz = -1, then find the value of x3 + y3 + z3

Answer»

We know that

x³ + y³ + z³ – 3 xyz = (x + y + z) (x² + y² + z² – xy – yz – zx)

=> x³ + y³ + z³ – 3xyz => (x + y + z) (x² + y² + z² + 2xy + 2yz + 2zx – 3xy – 3yz – 3zx)

(Subtracting and adding 2xy + 2yz + 2zx)

=> x³+ y³ + z³ – 3xyz = (x + y + z) {(x + y + z)² – 3(xy + yz + zx)}

=> x³+ y³ + z³ – 3 x (-1) = 1 x {(1) 2 – 3 x (-1)}

[Putting x + y + z = 1; xy + yz + zx = -1; xyz = -1]

=> x³ + y³ + z³ + 3 = 4

=> x³ + y³ + z³= 4 – 3

x³ + y³+ z³ = 1

In the given figure, G is the centroid of ∆ ABC, such that GD = 3 cm and BC = 4 cm. Then find the area of ∆ ABC.

Answer»

In ∆ GBC, BC = 4 cm and GD = 3 cm.

area (∆ GBC) = (1/2) x Base x Altitude = (1/2) x 4 x 3

= 6 cm²

ar (∆ ABC) = 3 x ar (∆ GBC) = 3 x 6 cm²

ar (∆ ABC) = 18 cm²
