OSSSC TGT Science PCM Mock Test - 1 - OTET MCQ

'Education-of-all-in-schools-for-all' is a tagline for Inclusive education.
Inclusive education is a platform that promotes and believes that every child should get equal opportunity irrespective of caste, creed, colour, religion and whether a child is a normal or special case. 
It mainly focuses on providing education to special children, along with children with non-special needs. It welcomes special-needs children to promote equality.
Hence, the correct answer is, 'Inclusive education.

The term used interchangeably with 'Motivation' is 'Need'. 
Motivation is a term that means the motive behind something. It means a person wants something, has a desire for something, wants to avoid something, and wants to escape from something. Having a desire for something is related to need. When we need something, then only a desire creates to have that thing.
Thus, this is the correct answer.

Pressure from parents, Fear of failure, and Competition with peers affects negatively. Only meaningful association is a factor that affects positively. Meaningful associations can be an association between teacher and student, As teachers may influence their student's learning. Forming an association with any such person to whom the students get knowledge and motivation whether it is peer association, Teacher-students association, etc.
Hence, the correct answer is, 'Meaningful association.'

Dyslexia is a type of learning disorder that involves difficulty in reading or recalling a sequence of letters in words (decoding) due to problems like speech sounds. It has an impact on areas of the brain that process language. It is also known as a reading disability.
Hence, this is the correct answer.

The electromagnetic waves are produced by vibration of an electric charge. This creates a wave which is both as electric and magnetic components. This way oscillates in perpendicular planes with respect to each other and in a phase.This creates all electromagnetic waves begin with an oscillating charged particle which creates an oscillating electric and magnetic field.

Human body has different resistances, when dry, resistance is 100,000 ohms. When wet because of sweat or water, resistance is only 1,000 ohms.

Time taken for 360° shift = 24 h
Time taken for 1° shift = 24/360 h = 4 min.
 

Arsenic is a chemical element with the symbol As and atomic number 33.
Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.
Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to the industry.

Si,P,C,N

Electronegativity increases along a period and decreases down the group.Nitrogen is expected to have maximum electronegativity.

Metallic oxides are basic in nature,

Atoms of different elements with different atomic numbers and the same mass number are known as isobars. 

Copper sulphate aqueous solution is blue in colour .

So Option D is correct

Doberneiner's Law of Triads
When elements with similar properties are taken three at a time and arranged in the ascending order of their atomic weights, the atomic weight of the middle element is the average of the atomic weights of the first and third elements.

Dobereiner’s “triads” (1829): groups of three similar elements: Examples:

• Li, Na, K
• Ca, Sr, Ba
• Cl, Br, I

Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation or self linking ability of carbon.

When HCl is added to iron filling then chlorine of HCl reacts with iron by evolving hydrogen gas. The iron dissolves, releasing hydrogen and making an iron chloride solution.

Fe + 2HCl → FeCl₂ + H₂ or

2Fe + 6HCl → 2FeCl₃ + 3H₂

-FeCl₂ is a greenish solution.

The metal that does not react with oxygen is Au (Gold).

The detailed explanation is as follows:

• Cu (Copper): Copper reacts with oxygen in the air to form copper oxide. This can be seen as the greenish color on the surface of copper objects.


• Au (Gold): Gold is a noble metal and does not react with oxygen under normal conditions. It is highly resistant to corrosion and oxidation.


• A and B: This option includes both copper and gold. Since copper reacts with oxygen and gold does not, this option is incorrect.


• Fe (Iron): Iron readily reacts with oxygen to form iron oxide, commonly known as rust. This is why iron objects can rust when exposed to moisture and air.

Therefore, the correct answer is option B: Au (Gold).

Gold is the most ductile metal. A wire of about 2 km length can be drawn from one gram of gold.

Trigonometric ratio  is correct.

∫x(5^x) dx
u = x,   dv = 5^x dx
du = dx,   v = (5^x/ln 5)
∫x(5^x) dx = [x(5^x)/ln 5](0 to 1) - ∫(0 to 1)(5^x)/ln 5 dx
= 5/ ln 5 - 0 - 1/ln 5[5^x/ln 5](0 to 1)
= 5/ln 5 - 5/(ln 5)² + 1/(ln 5)²
=5/ln 5 - 4/(ln 5)²
 

Above information has no common element in three of them and U of three sets forms sample set . Therefore option C is correct.

Area of the sector
⇒ Area of the sector
⇒ Area of the shaded region = 462 sq. cm

length of arc = 350m
Speed = 7km/hr
In one minute = (7*5/18*60)
=> (35*20)/6
= length of arc/radius
θ = (35*20)/(6*350)
θ = 1/3 radian

The volume of cube = side3
So the answer = 16 × 16 × 16 = 4,096 m³
Hence, Option D is correct.

The correct option is Option A.

If the angle is between 0 to 90 degrees then it will lies in the first quadrant.

The tanθ and sinθ have positive values, hence lies in first quadrant.

Let  It is given that left| , then , 

Putting these values in (1) , we get : 

∠A + ∠C = 180º ...(1)

Also, ∠A - ∠C = 60º ...(2)

On solving (i) and (ii), we get

∠A = 120º, ∠C = 60º
