HSSC TGT Math Mock Test - 7 - HSSC PGT/TGT MCQ

Energy Conservation:

• Energy conservation is not about making limited resources last as long as they can, that would mean that you are doing nothing more than prolong a crisis until you finally run out of energy resources altogether.
• Conservation is the process of reducing demand on a limited supply and enabling that supply to begin to rebuild itself. Many times the best way of doing this is to replace the energy used with an alternate source.
• The goal with energy conservation techniques is to

1. Reduce demand
2. Protect and replenish supplies
3. Develop and use alternative energy sources
4. To clean up the damage from the prior energy processes.
5. To reduce energy losses.

Methods of Energy Conservation:

• Install CFL Lights
• Lower the Room Temperature 
• Use Maximum Daylight
• Get Energy Audit Done
• Use Energy Efficient Appliances
• Drive Less, Walk More and Carpooling
• Switch Off Appliances When Not in Use
• Alternative Power (Switching to Solar Energy)  
• Zero Energy Balance

Note:

Energy conservation and efficiency may be related, but they have distinct definitions in the energy world.

Energy conservation involves using less energy by adjusting your behaviors and habits.

Energy efficiency, on the other hand, involves using technology that requires less energy to perform the same function.

Energy-saving light bulbs, large household appliances, smart thermostats, and smart home hubs like Constellation Connect are all examples of technology that can be energy efficient.

 Passion has a motivating factor; therefore, it is a significant need for high-quality learning and teaching.

Important Points

• Passion is seeking for the new and experiencing new ideas. 
• Passion is on the basis of effective teaching.
• The passion which is indispensable for learning and teaching facilitates learning through the desire and enthusiasm it creates.
• Passionate teachers by creating effective learning environments endeavor to increase the learning potentials of their students.

Example: Every week a teacher who has a personal interest in music shares with the class current news about musicians and music events and then displays the articles on a bulletin board. The teacher then encourages students to share current events of their own choosing with the class because the teacher is showing enthusiasm for a topic and therefore engaging students in the learning process.

Additional Information

• Only modeling any specific reading strategies or modeling making text-to-text connections by sharing the articles will not be able to keep students' motivation level high or encourage them to follow their passion. We learn by doing not only by reading or writing. 

Hence we can conclude that the right answer to this question is promoting a passion for learning.

Mostly composed of methane, the Compressed Natural Gas (CNG) is the cleanest of all the fossil fuels. It is called the cleanest fuel because when burnt, it produces only carbon dioxide and water vapor. Its key points are:

• It is used as an alternative to petrol and diesels because it is cheaper, greener and more efficient.
• It is compressed to increase the storage capacity of vehicles.
• It is environmentally friendly.
• It is safer than petrol and diesel.

Hence, the full form of CNG is Compressed Natural Gas.

Growth leads to the development of personality and behavioral traits, which is called maturation. In general, as organisms grow inside the structure, it is less quantitative and more emotional and cerebral. An illustration would be brain growth which makes it possible to manage activities that are more complicated.

Key Points

•  The maturation stage marks the end of growth and the consolidation of acquired mental, social, and emotional development. In essence, maturation is a process of internal improvement, alteration, and development of an organism's potential. Being mature is a necessary prerequisite for learning. So, Maturation is a developmental process.
• Learning is the development that results from effort and repetition. We are aware that learning and maturation interact to influence development. The constraints of maturation are imposed on growth. It suggests that even when learning is fostered, growth cannot advance past a certain point due to limitations in hereditary endowment. So, Maturation and learning work together to promote the development of an individual.
• For example, bicycle riding will be learnt only as a result of effort, practice and training.

Hence, it is concluded that Both A and B are true.

Charles H. Cooley was an American Sociologist he was best known for his concept of the looking-glass self.

Key Points

• Cooley is most famous for his theory of the looking-glass self. 
• According to this concept, the child self grows out of society's interpersonal interactions and the perceptions of others.
• He describes how we each create our own self-image. 
• The looking-glass self is the process by which people evaluate themselves based on how others see them. People first imagine how they appear to others.
• Second, they imagine how others judge them based on their appearance.
• Third, people have an emotional reaction to that imagined reaction such as pride or embarrassment.  It is the process by which people evaluate themselves based on how other see them.

Important Points

• George Herbert Mead developed a theory of social behaviorism to explain how social experience develops an individual’s personality. Mead’s central concept is the self: the part of an individual’s personality composed of self-awareness and self-image. Mead claimed that the self is not there at birth, rather, it is developed with social experience.
• Vygotsky focused on the connection between people and the sociocultural context in which they act and interact in shared experiences. 

​Hence, it can be concluded that this statement was given by Charles H. Cooley.

Any object or material that is used to facilitate learning and teaching can be considered as teaching-learning material (TLM). In other words, any material suitable for use in teaching is invariably a learning material.

Key Points

• We are familiar with materials specifically prepared for teaching and learning particular subjects or topics. Maps, charts, pictures, models, toys, marbles, coloured sticks, flashcards, number and alphabet cards are examples of some of the most common prepared TLMs known and used by teachers. Standard items like maps, globes, charts, scales, measuring tapes are usually purchased from the market.
• TLMs is based on the audio and visual effects produced by the materials. Accordingly, there are three types of TLMs: Audio, Visual and Audio-Visual.
  • Audio aids The materials or devices which call upon the auditory senses and thus help the individuals to learn through listening e.g. Radio broadcasts, Cassette and CD player.
  • Visual aids: The aids which call upon the visual senses and thus help the learners to learn through viewing. The important and under this head are Blackboard, Charts, Pictures, Graphs, Models, Film strips, Slides etc.
  • Audio-Visual Aids: The devices which require the auditory as well as visual senses and help the students to learn through listening as well as viewing. Examples of such aids are television, films and computer-assisted instruction.
• Still another way of categorizing TLMs is based on projected, non- projected or experiential.
  • Projected aids: Movies, epidiascope, the magic lantern, micro-projectors and projection with the overhead projectors, LCD projector are examples of projected aids.
  • Non-Projected aids: Chalkboard, felt board, bulletin board, photographs, posters, maps, charts, globes, specimens, and textbook illustrations, come under non-projected aids.
  • Experiential Aids: Field trips, educational tours, visiting important institutions and industries, observing experiments, demonstrations and natural phenomena are a few examples of experiential aids

 Thus, it can be concluded that micro-projectors - non-projected aids is not teaching-learning material - category of teaching-learning material.

Probability of an egg being defective =10/100=110
So, probability of an egg being non-defective=1−0.1=0.9
10 eggs are drawn successively with replacement.
So, the probability of getting no defective egg =(0.9)¹⁰
Hence, the probability that there is at least one defective egg = 1−(0.9)¹⁰

A proper subset of a set is any subset that is not the entire set itself.

For the set {1, 2, 3}:

1. The total number of subsets is 2^3 = 8.
   (Each of the 3 elements can either be in or out of a subset.)

2. Since only one of these subsets is the entire set itself, the number of proper subsets is 8 – 1 = 7

Let point A be (a, b) and point B is (-a, b)

∴ distance between A and B
 

A function is a relation in which no two ordered pairs have the same first element. A function associates each element in its domain with one and only one element in its range. R={(1,2), (1,4)(3,1),(5,1)} is not  a function because all the first elements are not different.

Total number of outcomes=90-1=89
No. of favourable outcomes = Total outcomes - One digit number =89-8=81
Probability of having a two digit number=Total number of outcomes/No. of favourable outcomes=81/89

Let the probability of losing the game be x
We know that sum of the the sum of probabilities is equal to 1
So
0.3+x=1
x=0.7

According to question, Diameter (BD) = 2 x radius = 2 x 12 = 24 cm
∴ Area of square

The orthogonal projection on x- axis is given by : 

f(x)= {−(x−1)/x²   x<1,   x(x−1)/x²  x≥1}
​f'(x)= {(x−2)/x³   x<1,      −(x−2)/x³   x≥1}
​x<1, if f′(x)<0 (for f(x) to be monotonically decreasing
⇒ (x−2)/x³<0
⇒x∈(0,2)
But x<1 ⇒ x∈(0,1)
For x≥1, if f′(x)<0
⇒ −(x−2)]/x³<0
⇒(x−2)/x³ > 0
⇒x∈(−∞,0)∪(2,∞)
But, x≥1   ⇒x∈(2,∞)
Hence, x∈(0,1)∪(2,∞)

We know that the midpoint of two points (x1, y1) and (x2, y2) is given by:
((x1 + x2) / 2, (y1 + y2) / 2)

Given midpoint is (2, 2p + 2).

So,
(3p + (-2)) / 2 = 2 --> (3p - 2) / 2 = 2
Multiply both sides by 2:
3p - 2 = 4
3p = 6
p = 2

Now, substitute p = 2 in the second part:
(4 + 2q) / 2 = 2p + 2
(4 + 2q) / 2 = 4 + 2
(4 + 2q) / 2 = 6
Multiply both sides by 2:
4 + 2q = 12
2q = 8
q = 4

So, p = 2 and q = 4.

Answer:
c) 2, 4

If A = [a_ij]_2x2 where a_ij = i + j, then, 

According to definition of parabola , is is the locks of the points in that planes that are equidistant from both focus and directrix.

Given, focus : (-3,0)
directrix : x + 5 = 0
Let (x ,y) is the point on the parabola .
∴ distance of point from focus = distance of point from directrix
⇒ √{(x + 3)² + y²} = |x + 5|/√(1² + 0²)
⇒ √{(x + 3)² + y² } = |x + 5|
squaring both sides,
(x + 3)² + y² = (x + 5)²
⇒y² = (x + 5)² - (x + 3)²
⇒y²= (x + 5 - x - 3)(x + 5 + x + 3)
⇒y² = 2(2x + 8) = 4(x + 4)

Hence, equation of parabola is y² = 4(x + 4)

It is given that :  are unit vectors such that 
then :

Here, Area of circle (A) = πr² and Circumference of circle (C) = 2πr
 
Putting value of C in A = πr², we get

Let middle point of chord is P(h,k)
Thus equation of chord with mid point P is,  kx+hy=2hk
Given slope of this chord is m
⇒ −k/h = m
⇒k+mh=0
Thus locus of P(h,k) is, y+mx=0
