OSSSC TGT Science PCM Mock Test - 8 - OTET MCQ

The techniques required to motivate students of a class are: setting induction, use of blackboard to show illustrations as well as students in the active participation. Hence, option 4 is the correct answer.

'Modelling' refers to imitation. Imitation is directly linked to observation. Bandura claims that children continually learn desirable and undesirable behaviours through observational learning. Observational learning suggests that an individual's environment, cognition, and behaviour all integrate and ultimately determine how the individual functions.

All differences between individuals may be interpreted by the facts of heredity or nature, environment or nurture, and training. Individuals have various endowments, abilities and capacities, provided by heredity which decide the path of progress and development of an individual. Environment also plays a key role in individual differences. No person from birth to death get the same environment. Both nature (heredity) and nurture (environment) are strong contenders in order to distinguish one individual from another.

Gender discrimination may lead to diminished effort or performance in education or the labour market, which itself gives rise to negative outcomes. What remains unclear from this line of research, however, is to what extent perceptions of discrimination correspond to some reliable depiction of reality. Because events may be misperceived or overlooked, perceptions of discrimination may over- or under-estimate the actual incidence of discrimination.

In sports coaching, play and practice are said to be two of the key variables that influence skill acquisition. Hence, option 4 is the answer.

Training in advance of normal maturation is beneficial or harmful depending on the method used in training. If the methods used are forceful, then it can be harmful, but if the methods used in the training are normal and fit for the person, then it will be beneficial.

Vygotsky's theory of cognitive development focuses on linguistic, social and cultural development in his theories but does not focus on biological development. It is because of social interactions or imaginative plays, cognitive development takes place in the children. He believes that socialization starts with the schools and communities that engage children in discovering and exploring new things.
Hence, the correct answer is, 'Biological.'

Girl students are as good at Mathematics as boys of their age. Abilities and skills are not limited to a particular gender. Capabilities in Mathematics is nothing to do with gender. Both are equally capable. Girls are not less than boys in any sector, field.
Hence, this is the correct answer.

Explanation:explanation none

λ is the wavelength of light in air.

Let t be the distance between points S and A.

Optical path length travelled by light via SB

Optical path length travelled by light via SA = μt
Path difference between points  A and B
Now  phase difference

Hence,    

EMF is equal to potential difference between plates when the battery is not connected to any external circuit. 
Potential difference is due to the charge accumulation on the plates. So, EMF produces a potential difference between the two terminals which drives the current.

When the deviation is minimum, then the incidence angle and emergence angle are equal and this is possible only when the refracted ray inside the prism is parallel to the base of the prism. 
Minimum deviation is given by δ=2i−A, where A is prism angle.

Here 4 Ω, 12 Ω, 6 Ω when connected in parallel results in 2Ω. to reduce it to half we have to join 1\R original = 6\12 for reducing it to half we have to join 6 , 12 Ω  resistors in parallel (6\12) + (1\ 12 × 6) = 12\12 = 1 ohm . Half of its original value therefore option a is correct.

Focal length for lens,

Here, μ_g = 1.5, R₁ = 20 cm, R₂ = −30cm

Focal length for mirror, 

∴ Equivalent focal length

Hence, this system behaves like a concave mirror of local length -60/11 cm

The molecules of air and other fine particles in the atmosphere have a size smaller than the wavelength of visible light. These particles are more effective in scattering light of a shorter wavelength at the blue end than the light of the longer wavelengths at the red end. The red light has a wavelength 1.8  times greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in the air scatter the blue color more strongly than red color. The scattered blue light enters our eyes and we see the blue color of the clear sky.

In a current-carrying conductor, by varying the electric current, the magnetic field is generated. The direction of the magnetic field generated will be perpendicular to the conductor.
The direction of the magnetic field can be determined as wrapping the right-hand fingers around the wire and the direction of the current is indicated by the thumb.
Ampere’s law is used for determining the magnetic field of a long conductor:
B=μ0I/2πr
Where,

• I is the current in Amperes

• r is the radial distance in metres

• B is the magnetic field in Tesla

Molecular mass is the sum of the atomic masses of all atoms in a molecule, compared to the mass of a carbon-12 atom.

carboxylic acid contains -COOH group.

Dry ice, sometimes referred to as "cardice", is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue. 

The quality and taste of honey depends upon the flora, pasturage or orchards available for the nector and pollen collection. Pasturage/orchard flora of honey bees include a variety of flowering plants such as mango (aam), coconut (narial), almond (badam), tamarind (imli), ber, Berseem, litchi, cotton,shishame,apple,mahua,coriander,cashew,coffee,rubber plants,guava,sunflower,neem etc.
