HP TET TGT Non Medical Mock Test - 9 - HP TET MCQ

Diversity among learners could be with reference to their learning abilities, socio-economic backgrounds, cultural
variations or even emotional behavioral characteristics. The system of education calls for providing equal opportunity to every child for optimal development. 

• Inclusive education helps the children in schools to develop higher levels of tolerance for people with diversities in general and for those who are disadvantaged.
• There is so much of diversity among a group of children belonging to the same age group.
• Children differ with regard to their home background, motivation and ability to learn, personal attributes contributing to success in academics, attitudes, interests and commitments.
• Inclusive education helps the development of children in different ways. Students with specific challenges make gains in physical, cognitive and social development and motor skills. They do well when the general environment is adjusted to meet their needs.

Hence, it can be concluded that Inclusive education helps the children in schools to develop higher levels of tolerance for people with diversities in general and for those who are disadvantaged.

A picture will be the best teaching aid to teach the subject of biology. A number of pictures can be used to teach each of the processes individually.

(2 x 58.5 = 117 g) 22.4 L (STP)
117g of NaCl = 22.4 L of Cl₂
50 g of NaCl = 22.4/117 x 50 = 9.57 L of Cl₂ at STP

Seconds in 3 days can be calculated as

Molar mass of N is 14.0067 g/mol.
Molar mass of P₂O₅ is 30.973762*205 = 6349.62121 g/mol.
Molar mass of K₂O is 39.0983*20 = 781.966 g/mol
Ratio of masses is 30:10:10
Therefore for each 50 g of fertilizer:
For N: 30 g / 14.0067 g/mol = 30/14.0067 moles
For P₂O₅: 10 g / 6349.62121 g/mol = 10/6349.62121 moles
For K₂O: 10 g / 781.966 g/mol = 10/781.966 moles
Ratio of elements in terms of moles:
30/14.0067 : 10/6349.62121 : 10/781.966
30/14.0067*781.966/10 : 10/6349.62121*781.966/10 : 10/781.966*781.966/10
167.484 : 0.123 : 1.0

Transition elements belong to d block and the first transition elements is scandium(whose atomic no. is 21)

+3 charge means no of electrons will be 3 less than no. of protons. So no. of protons will be 21. So atomic no. is 21.

It is believed that Noble gases don't form (or rather don't easily form bonds). This way only Van der Waals radius is measured.

The rationale here is based on the fact that noble gases have very low chemical reactivity and their atomic radii are non bonded.

Δx·mΔv = h/4π
Δx - 1000 Å = 1000 x 10^-10 m or 10^-7 m

[Ni(CN)₄]^2- in this, Ni has dsp² hybridisation with square planar geometry and it is diamagnetic.

Area of square card = 1 mm × 1 mm = 1 mm²
Focal length of magnifying lens, f = +10 cm
Object distance, u = -9 cm
According to thin lens formula

or v = -90 cm

∴ Apparent area of the card through the  lens 
= 10 × 10 × 1 mm²
 = 100 mm²
 = 1 cm²

is the right answer.

The orderly distribution of electromagnetic radiations according to their wavelength or frequency as called the electromagnetic spectrum. Radio waves are electromagnetic waves of the frequency range from few Hz to 10⁶ Hz.

3. 1.5

Solution: Let the radius of curvature of the convex surface of the plano-convex lens be RRR. The focal length of a concave mirror is related to the radius of curvature by f=R2f = \frac{R}{2}f=2R​.

1. When the plane side is silvered, the system behaves as a concave mirror with focal length 30 cm. The effective focal length fefff_{\text{eff}}feff​ of this system can be found using the mirror formula and lens formula combined, but given the scenario, we focus on this system.

2. When the convex side is silvered, the system behaves like a concave mirror with focal length 10 cm.

By using the relations for combined focal length and refractive index of the plano-convex lens, and applying these boundary conditions, the refractive index nnn of the material of the lens is determined to be 1.5.

A real image is defined as one that is formed when rays of light are directed in a fixed point.  A real image can be projected or seen on a screen. The best example of a real image is the one formed on a cinema screen.
A virtual image is defined as the opposite of a real image, therefore an image that cannot be obtained on a screen is referred to as a virtual image. The explanation for this is the fact that the rays of light that form a virtual image never converge therefore a virtual image can never be projected onto a screen. The best example of a virtual image is your reflection in the mirror.
Real images are produced by intersecting rays while virtual images are produced by diverging rays.
Real images can be projected on a screen while virtual ones cannot.
Real images are formed by two opposite lenses, concave and convex.
Virtual images are always upright while real images are always inverted.
 

Long distance radio broadcasts use shortwave bands because only these bands can be refracted by the ionosphere.

As the given two matrices are 3x3 and 3x1 respectively
hence, the product will be a 3x1 matrix
so, {(1*0+ 2*2+ 0*x) (2*0+ 0*2+ 1*x) (1*0+ 0*2+ 2*x)}
= {4, x, 2x} as a 3x1 matrix

A’ = {(1,-1,5) (0,0,2)}   B = {(-2,0) (0,2) (3,4)}
B’ = {(-2,0,3) (0,2,4)}
2B’ = 2{(-2,0,3) (0,2,4)}
2B’ = {(-4,0,6) (0,4,8)}
(A’ - 2B’) = {(1,-1,5) (0,0,2)}  - {(-4,0,6) (0,4,8)}
= {(5,-1,-1) (0,-4,-6)}
 (A’ - 2B’)’ = {(5,0) (-1,-4) (-1,-6)}

 P(n) : Aⁿ = {(1+2n, -4n), (n,(1 - 2n))}
= P(k + 1) = {(1+2(k+1), -4(k+1)), (k+1, (1 - 2(k+1)}
= {(1+2k+2, -4k-4) (k+1, 1-2k-2)}
= {(2k+3, -4k-4), (k+1, -2k-1)}

Given: y = sin 3x . sin³

= 3 sin²x.sin 4x

If A and B are symmetric matrices of the same order, then , AB + BA is always a symmetric matrix.

Plane is parallel to line i.e., normal of plane is perpendicular to the line
2 × 1 + (-1) × (-2) + 1 × a = 0
2 + 2 + a = 0
a = - 4

Let x' and y' be the reflection of x and y, therefore :



Hence, reflection is on the line - x-y = 0⇒ x + y = 0

cos 4x = cos 2x

Amazon, with a market value of $299.3 billion, is recognized as the most valuable brand in the world as of January 2024, showcasing its influence and diverse ventures in commerce, technology, and entertainment.

New York Declaration on Forests:

Spurred by the UN Secretary General’s Climate Summit in September 2014, the New York Declaration on Forests is a political declaration that brings together governments, companies and civil society actors including indigenous peoples organizations with the common aim of halving the loss of natural forests by 2020 and striving to end it by 2030. So, statements 1 and 2 are correct.

The New York Declaration on Forests is a non-legally binding political declaration. So, statement 3 is incorrect.

The Declaration is currently endorsed by over 200 entities including more than 50 governments, more than 50 of the world’s biggest companies, and more than 50 influential civil society and indigenous organizations. So, statement 4 is correct.

India is not a signatory of the declaration. So, statement 5 is incorrect.

Former Indian women's hockey team captain, Elvera Britto has passed away at 81 due to old-age-related problems on April 2022. Elvera Britto led Karnataka's domestic team to win seven national titles. She ruled the domestic circuit from 1960 to 1967. She also represented India against Japan, Sri Lanka, and Australia. She is the second women hockey player to be conferred with the Arjuna Award(1965) after Anne Lumsden.

The World Day of War Orphans is observed on January 6, 2024, dedicated to highlighting the struggles and needs of children who are the most vulnerable victims of war.
