Indian Air Force Agniveer Science & Other than Science Mock Test - 5 - Indian Air Force Agniveer Vayu MCQ

The Correct answer is Electron Microscope. 

• The electron microscope uses the wave nature of electrons for its functioning.
• It uses a beam of accelerated electrons as a source of illumination.

Electron Microscope:

Whereas,

• In a photocell, light waves are used. 
• A tokamak is a device that uses a powerful magnetic field to confine plasma in the shape of a torus. 
• The magnetic spectrum made up of gamma rays, x-ray, ultraviolet rays, visible light, infrared, microwave and radio rays is used in an aeroplane. 

Tension, thrust, weight are all common forces in mechanics whereas impulse is not a force.
Impulse = Force x Time Duration

Unlike linear motion, where velocity and acceleration are directed along the line of motion, in circular motion the direction of velocity is always tangent to the circle. This means that as the object moves in a circle, the direction of the velocity is always changing. A linear velocity of a particle performing circular motion, which is directed along the tangent to the circular path at given point on the circular path at that instant is called instantaneous velocity. It is also called as tangential velocity.

A reversible process gives the maximum work.

∆ U = ∆ Q - ∆ W
In an adiabatic process ∆Q is zero, therefore
∆ U = - ∆ W

Energy stored in capacitor

According to Ohm’s law, V=I R. Therefore R=V/I

Maxwell’s Fourth Equation
It is based on Ampere’s circuital law. To understand Maxwell’s fourth equation it is crucial to understand Ampere’s circuital law,
Consider a wire of current-carrying conductor with the current I, since there is an electric field there has to be a magnetic field vector around it. Ampere’s circuit law states that “The closed line integral of magnetic field vector is always equal to the total amount of scalar electric field enclosed within the path of any shape” which means the current flowing along the wire(which is a scalar quantity) is equal to the magnetic field vector (which is a vector quantity)

Refraction of light ray through the atmosphere may cause different magnification in mutually perpendicular directions.

Sunlight enters the Earth's atmosphere from the vacuum of space. The refractive index of air with respect to vacuum is 1.0029. This means that the speed of light in air is 1.0029 times slower than the speed of light in vacuum. This causes the light rays to bend towards the normal (refraction). 

• n(A ∪ B) = n(A) + n(B) − n(A ∩ B) = 12 + 9 − 4 = 17
• Now, n((A ∪ B)^c) = n(U) − n(A ∪ B) = 20 − 17 = 3

Let y = tan^-1(-1)

tan y = -1

tan y = tan(-π/4)

Range of principal value of tan^-1 is
(-π/2 , π/2)

SInce - 1 is negative,
the principle value of tan^-1(-1) is - π/4​

9x² + 5y² - 30y = 0
9x² + 5(y−3)² = 45
We can write it as : [(x-0)²]/5 + [(y-3)²]/9 = 1
Compare it with x²/a² + y²/b² = 1
e = [(b² - a²)/b²]^½
e = [(9-5)/9]^1/2
e = (4/9)^½
e = ⅔

In vector form Distance between two parallel lines  given by :

After the experiment, the result of the random experiment is known. An outcome is a result of a random experiment. The set of all possible outcomes is called the sample space.

ρ = (b(xy) * b(yx))
But sign of ρρ is same as sign of b(xy), b(yx)
Therefore, ρ = 2/7

You can get

29+(18*1-2) = 29+16 = 45
45+(18*2-2) = 45+34 = 79
79+(18*3-2) = 79+52 = 131
131+(18*4-2) = 131+70 = 201

9*0.5+0.5 = 5
5*1+1 = 6
6*1.5+1.5 = 10.5
10.5*2+2 = 23
23*2.5+2.5 = 60

M x N → M is the father of N

N - C → N is the sister of C

and C + F → C is the brother of F.

Hence, M is the father of C or C is the son of M.

C+2E+3H+5M

Except BDFL, all other groups follows similar pattern.

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. 

Fat-soluble vitamins are stored in the body in organs such as the liver. Most of the vitamin A that we consume goes to the liver to be stored until it is needed by another part of the body.

Thar Express is an international train that con-nects Karachi, Pakistan to Bhagat Ki Kothi, India. Six kilometres apart, Munabao and Khokhrapar are the two last railway stations of the India-Pakistan border. Jamrao, Mirpur Khas, Shadi Pali, Saeendad. Barmer, Pithoro, Dhoro Naro, and Chhore are some of the stations. Bhagat in Kothi is a train station 5km from Jodhpur Railway Station.

The NCC Integrated Software launched by Raksha Mantri Rajnath Singh aims to digitalize the entire process from the stage of cadet enrollment in NCC to exit registration as an alumni. The software simplifies the issuance of certificates and creates a comprehensive database of NCC cadets, aligning with the vision of digitization and the "Once a Cadet always a cadet" principle.

A is third to the right of I.
Hence option A is correct.

Final Arrangement:

Common Explanation:

Reference:
G is second to the right of A.
Neither C nor A faces away from centre.
The persons whose name starts with vowel do not sit on the shorter side of the table.

Inference:
With respect to second hint, we can say that A faces centre.
As per third hint it is clear that A does not sit at the shorter side. Thus following three arrangements are possible.

Reference:
B, who faces centre sits second to the left of E.
J is on the immediate right of F, who is at a gap of two persons from E.
E is adjacent to G.
I is on the immediate left of F.
I is neither adjacent to A nor to C.
The persons whose name starts with vowel do not sit on the shorter side of the table.

Inference:
As per the hints, one more case arises from each of the three cases.

Both the cases get eliminated as I is adjacent to C in both the cases which violates the fifth hint.

Case-2A eliminates as I is adjacent to C, which violates the fifth hint.

Case-3 gets eliminated as I is adjacent to A, which violates the fifth hint.
Thus we are left with case-2 only.
 
Reference:
The immediate neighbors of F face away from centre.
Neither C nor A face away from centre.
Three of them face away from centre while the rest five face towards the centre.
 
Inference:
Thus as per both the hints we can say that C faces centre and J and I face away from centre.
As per third hint, we can determine that the only left person i.e. G also faces away from centre.
