OSSSC TGT Science PCM Mock Test - 6 - OTET MCQ

For studying a map, the knowledge of distances, places and directions are very important. So, if a teacher has the knowledge of these factors, she can easily make the students understand maps.

The Ministry of Women and Child Development makes laws and regulations to take care of the women and child development in India.

According to Piaget, after the age of seven, children move into the second stage of morality from the first stage of the morality of constraint, and this stage is known as the Morality of Cooperation. 
The Morality of Cooperation stage is defined as the stage in which children can see from the other's point of view. They start recognising that the rules are not absolute they can be changed as per the necessary situations.
Hence, the correct answer is, 'Morality of Cooperation.'

Tan(90-i)=14/11.2
Cot i=14/11.2
I=cot-1(14/11.2)
I=39.4^o

The resistance of a conductor depends on thickness (cross sectional area of the wire), length and temperature.
Resistivity is defined as the measure of the resisting power of a specified material to the flow of an electric current.
R=ρ(I/A)​
where R = Resistance of the conductor
ρ = Resistivity of the conductor
l = length of the conductor
A = Area of cross section
i.e., ρ=R (A​/l)

No force is exerted by a magnetic field on a stationary electric dipole because:

• The electric dipole consists of two equal and opposite charges.
• When stationary, the dipole does not experience any motion through the magnetic field.
• As a result, there is no induced current or change in magnetic flux.
• The magnetic field only affects moving charges or current-carrying conductors.

Therefore, the correct understanding is that a magnetic field does not exert a force on a stationary electric dipole.

a², = I A B
The 40cm of wire can bent into a square with slides of 10cm
A=(10cm)²=100 cm²
τ=I A B
τ=(20A)(100cm²)(0.52T)
τ=1040 A cm²T[1m²/10⁴ cm²]
τ=0.1040 N-m

• Yes, sound waves are longitudinal, meaning that they oscillate parallel to the direction of their motion. So diffraction takes place in the sound waves.
• Since there is no component of a sound wave's oscillation that is perpendicular to its motion, sound waves cannot be polarized.

We have, (1/v)−(1/−90)=1/f⇒(1.5−1)(1/30)=1/60
∴ v=180 cm
∴|m|=∣v/u∣=180/90=2.0

The relation between radius of curvature, image distance and object distance is given by
n₂/v-n₁/u=n₂-n₁
un₂-vn₂/vu=n₂-n₁/R
R=vu(n2-n2)/un₂-vn₂
=uv(2)/u(2)-v(1)
=[uv/2u-v)

Z = 79 [Xe]4f¹⁴5d^10.6s¹ (n = 6)
As n = 6, the element belongs to 6^th period.
Group = ns + (n - I)d, I + 10 = 11

Electronegativity decreases down the group.

The alkaline hydrolysis of oils and fats is called saponification. The estrr, on treating with a base such as NAOH  is converted back to alcohol and sodium salt of Carboxylic acid. The reaction is known as saponification.

Acids produce H⁺ ions when dissolved in water. These ions are essential to the acidic properties of the solution and play a significant role in various acid-base reactions.

Correct Answer :- b

Explanation:- D-Fructose (levulose or fruit sugar) is the sweetest of all sugars. It is found in honey, corn syrup, and in the fruit and other parts of plants. It is much sweeter than sucrose (cane sugar).

Nitrogen is more electronegative than phosphorus. On moving down a group, the number of shell increases. Therefore, the valence electrons move away from the nucleus and the effective nuclear charge decreases. 

Hund's rule says , when electrons are filled in orbitals of equal energy, one electron enters each orbital until all the orbitals contain one electron with the same spin direction. Then the pairing of electrons take place.

Thus in electronic configuration, the electrons in p subshell are filled in 3 orbitals such that every orbital contains one electron each. The fourth electron will be paired up with the first electron and the other two electrons remain unpaired.

Mutually exclusive means no common event.
if 2 comes on either dive then sum can't be greater than 8.It will always less than or equal to 8.
So mutually exclusive.

R = {(x, y): y is a factor of x, x, y∈ N}
As we know that 2 is a factor of 4
So, according to the options (4, 2) ϵ R

Since √2 and √5 are both irrational numbers, therefore  is an irrational number.

we know sin(90 - a) = cos(a) 

cos(90 - a) = sin(a)

sin(a) = 1/cosec(a)

sec(a) = 1/cos(a)

cos40 = cos(90-50) = sin50

cosec40 = cosec(90-50) = sec50

so our expression becomes

sin50/sin50 + sec50/sec50 - 4cos50 / sin40

= 1 + 1 - 4(1)   since cos50 = sin40

= -2

Given: Radius (r) = 10 cm
Let side of the square be x cm
Now. using Pythagoras theorem.
x² + x² = (2r)² ⇒ 2x² = (20)²
⇒ 2x² = 400 ⇒ x² = 200 sq. cm
Therefore. area of the square = 200 sq. cm. 

The transpose of a matrix is a new matrix whose rows are the columns of the original. (This makes the columns of the new matrix the rows of the original). Here is a matrix and its transpose:        is matrix and its transpose is  

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

All the elements in set-A are presented in set-B. So "A" is a subset of "B".
