KVS PGT Physics Mock Test - 10 - KVS PGT/TGT/PRT MCQ

The sentence puts forward a proposition that the government is planning to launch a new scheme in the future that will be working then. Thus, the verb forming the sentence has to be in the future continuous tense. 
Thus option 3 is correct as 'will be launching' is in future continuous tense.

Community involvement can be assessed in terms of the active involvement of individuals, local leaders, institutions, and organizations to provide support. The community includes all the members of the families in the immediate neighborhood, community workers, and personnel working in various institutions.

Key Points  
The progressive involvement of the community would be reflected in increased mobilization and utilization of local resources, and enhanced contribution and participation by the individuals and beneficiaries.

The contribution of the community to education are:

•   Supply of food materials, like grains and pulses. These may be procured at the time of harvesting.
•  Local vegetables, especially green leafy and yellow vegetables.
• Local fruits.
• Providing financial assistance.
• Academic and administrative support 
•  Waste material from households or from artisans e.g., empty plastic boxes, cartons, beads, old toys, pieces of cloth, wool, old newspapers, magazines, pieces of wood, potter’s clay, and so on.
•  Remember to keep a record of any cash received as well as its use carefully.

Thus, it is concluded that providing financial assistance and academic and administrative support is correct with reference to the contribution of the community to education.  

Piaget’s theory tells us that the child is born with a mental/cognitive structure that develops and attains maximum growth around the age of 14 or 15 years.

Key Points

• Piaget’s theory provides a comprehensive picture of cognitive development from birth to the age of 14 or 15 when cognitive development attains its peak.
• Piaget conceives cognitive development as consisting of a series of stages, each characterized by certain kinds of behaviors, and certain ways of thinking and solving problems.
• All the age-specific stages have been grouped under four broad stages:

Hence, we can conclude that Jean Piaget's theory of child development is based on Cognitive development.

Work Education is a type of education that includes manual labor as a means of imparting knowledge and skills to students.

• In India, the concept of work education was introduced in the education system after independence.

Key Points

• The National Policy on Education was first formulated in 1968 and revised in 1986 and 1992. The policy aims to provide quality education to all sections of society and improve the educational system in India.
• National Policy on Education conceived work education as purposive and meaningful manual work that results in goods or services which are useful to society.
• Work education is an integral part of the policy as it is believed that it helps in the overall development of the students.
• The policy states that work education should be introduced at the secondary stage of education and should be made compulsory for all students.
• The aim of work education is not just to impart knowledge and skills but also to develop a sense of responsibility, self-reliance, and self-confidence among students.
• It is believed that work education helps in the holistic development of students and prepares them for the challenges of the real world.

Hence, National Policy on Education conceived work education as purposive and meaningful manual work that results in goods or services which are useful to society.

Additional Information

• The Bhore Committee was a health survey and development committee established by the Government of India in 1943. 
• The Kothari Commission, also known as the Education Commission, was established by the Government of India in 1964 to evaluate the state of education in the country and make recommendations for its improvement. 
• The National Curriculum Framework (NCF) 2005 was formulated by NCERT to provide guidelines for school education in India.

The programmes of early childhood care and education should be holistic in nature rather than providing nutrition, health and education services as piece-meal services. There are a number of these programmes being run in our country as well as in other developing countries. It is important to learn not only from one's own experience but also from that of others.

Key Points

• Recognising the holistic nature of child development, viz., nutrition, health and social, mental, physical, moral and emotional development, Early childhood Education will receive high priority.
• An ECCE programme must be holistic in nature. Further, to increase its practical viability and success, logical, implementable combinations can be tried. For instance, child care can be attached as a service to existing income-generating programmes for women.
• In most of the ECCE programmes in our country, the education component is either very low or is formal and focusses on the 3 R's (reading, writing and arithmetic). More effort is required to emphasise to families and early childhood workers, the value of play and the use of informal methods of education for young children.
• Early childhood education must essentially be through the play-way method and activity-based approach. Gradually the same should be integrated into primary schools as well, at least for the first couple of years, for better quality education and improved retention rates.

Hence, we can conclude that Early childhood Care &Education is a programme that is focused on the holistic development of the child.

Tests may be of different forms, such as psychological test used to measure mental and behavioral traits, achievement test to assess performances of students, etc. They can be used to assess both the scholastic and co-scholastic abilities of the students.

Key Points

• The anecdotal records provide a means for the observation of one’s behavior
• The anecdotal records are used to record specific observations of individual student behaviours, skills and attitudes as they relate to the outcomes in the program of studies.
• Anecdotal records should be factual report of an event in a child’s life reported with adequate details so that it is a meaningful evidence of his/her behavior.
• A good Anecdotal record has the following features:
  • It provides an accurate description of any event.
  • It describes a setting sufficiently to give the events meaning.
  • If it includes interpretations or evaluation by the recorder, this interpretation is separated from the description and its different status is clearly identified.
  • The event relates to the child’s personal development or social interactions. 

Hence, we can conclude that the anecdotal records are used to record specific observations of individual student behaviours, skills and attitudes as they relate to the outcomes in the program of studies.

Additional Information

The electric and magnetic fields are Parallel and separated because magnetic field applies force only on moving charge and electric field applies force both moving and stationery charges.

Mathematical constants don't have any dimensions hence, it is dimensionless and phase constant is in angle therefore, the unit is radian.

Explanation:Time period of an oscillatory motion is the smallest interval of time for one complete oscillation.As when we apply the force on the bob,bob moves from mean position to extreme position then form extreme position to mean position and then again from mean to extreme in opposite direction and at last come to mean position.The time taken by bob in this whole process is called period of oscillation.

x₁ + x₃ = l

Differentiating with respect to time,

  we get,  v₁ + v₃ = 0

  Again differentiating with respect to time, 

Differentiating with respect to time,  v₁ + v₂ – 2v₃ = 0  

Again differentiating with respect to time, a₁ + a₂ – 2a₃ = 0  

Since, P_r​=P_b​ 
r for red and b for blue.
P_r​=P_b​
or, n_r​× (hc/λr)  ​=nb​× (hc​/λ_b)​
or,  ​(n_r/n_b)​​= λ_r​​/λ_b ​
Since, the wavelength of red bulb is greater than the wavelength of blue bulb.
or,  n_r​>n_b

Emf = - N(∆magnetic flux)/∆t
N=100turns
∆magnetic flux= -30×10-6Wb
∆t = 0.04sec
Emf = -(100turns)(-30×10-6)/(0.04sec)
Emf = 0.075V
 

An atom has a nearly continuous mass distribution in Thomson’s model, but has a highly non-uniform mass distribution in Rutherford’s model.

Correct Answer :- d

Explanation : a) A topological sort of a directed acyclic graph (DAG) is any ordering m1, m2, …, mn of the nodes

of the graph, such that if mimj is an edge then mi appears before mj . Any topological sort of a

the dependency graph gives a valid evaluation order for the semantic rules. 

b) The parse tree can be annotated with synthesized or inherited attributes. The parse tree can also be indicated with an arrow mark to indicate the manner in which the value gets propagated between the nodes of the parse tree. This graph is called as dependency graph as it indicates the dependency between nodes for deriving the values. This graph is an acyclic graph which doesn’t have a cycle. The presence of a cycle indicates that the graph is incorrect as the dependence of nodes for deriving values cannot be predicted. Edges in the dependence graph show the evaluation order for attribute values and thus the graph is a directed one.

Rate of change of area with remain same even if wire is replaced by semi-circular wire, 
∴ induced current will be same as earlier one as I = (e/R) & e i.e. induced emf is function of area because
e = – N (dɸ/dt) = – N (d/dt) (ABcoswt).
 

Electric flux density is the charge per unit area. Hence it is a function of charge and not any of the other values.

Distance between the slits, d=0.28×10−3 m

Distance between the slits and the screen, D=1.4m

Distance between the central fringe and the fourth (n=4) fringe, 

u=1.2×10−2 m

In case of a constructive interference, we have the relation for the distance between the two fringes as:

u=nλD/d

⇒λ=ud/nD=6×10−7m=600nm

The plate which connected to high voltage generator induces negative charge on ball which causes attraction. When the ball strikes the positive plate, charge distribution again takes place that is the bass becomes positive and repulsion takes place. When it strikes the plate which connected to earth than its charge goes to earth and again it will be attracted towards positive plate. Hence the ball swings backward and forward hitting each plate in turn.

A tuning fork is made of an alloy of steel, nickel and chromium, called elinvar, i.e. the material for which the elasticity does not change.

Explanation:The induced EMF is expected to be constant in the case of a rectangular loop. In case of a circular loop, the rate of change of area of the loop during the passage out of the field region is not constant, whereas it is constant for rectangular loop.

Torque on a dipole kept in external electric field is given by the expression,

• Eddy currents are the currents induced in solid masses when the magnetic flux threading through them changes.
• Eddy currents also oppose the change in magnetic flux, so their direction is given by Lenz’s law.

The Davisson-Germer experiment demonstrated the wave nature of the electron, confirming the earlier hypothesis of deBroglie. Putting wave-particle duality on a firm experimental footing, it represented a major step forward in the development of quantum mechanics. The Bragg law for diffraction had been applied to x-ray diffraction, but this was the first application to particle waves.

Water is used as a coolant in automobiles radiators because it has high specific heat capacity. So, it absorbs a large amount of heat for a degree rise in temperature.

When a tangent is drawn at any point on field line then that tangent gives the direction of electric field at that point

Explanation:

- Inductive Circuits:
In purely inductive circuits, the current lags behind the voltage by π/2 (90 degrees). This is because in an inductive circuit, the voltage leads the current due to the phase shift caused by the presence of inductance.

- Phase Relationship:
When an alternating current passes through an inductor, a back EMF is induced in the coil which opposes the flow of current. This causes the current to lag behind the voltage in an inductive circuit.

- Mathematical Representation:
Mathematically, this phase shift can be represented as a phase angle of π/2 (90 degrees) between the current and voltage in a purely inductive circuit.

- Conclusion:
Therefore, in purely inductive circuits, the current lags behind the voltage by π/2 due to the inherent characteristics of inductors to oppose changes in current flow.
