Indian Air Force Agniveer Science & Other than Science Mock Test - 7 - Indian Air Force Agniveer Vayu MCQ

The sign of acceleration does not tell us whether the particle's speed is increasing or decreasing. The sign of acceleration depends on the choice of the positive direction of the axis.
For example: If the vertically upward direction is chosen to be positive direction of the axis, the acceleration due to gravity is negative. If a particle is falling under gravity, this acceleration though negative results in increase in speed.

Angular displacement is measured in units of radians. 2 pi radians equals 360 degrees. The angular displacement is not a length (i.e. not measured in meters or feet), so an angular displacement is different than a linear displacement.

• Gravitational force strictly follows Newton’s Third Law of motion i.e. for every action force there is an equal and opposite reaction force.
• Gravitational forces add up like vectors i.e. they obey the principle of superposition.

A body is said to be plastic when its coefficient of restitution or reformation is zero that means that whatever hits it loses its all kinetic energy once the body gets deformed does not reform.

Equivalent capacitance for three capacitors (C₁, C₂ & C₃) in series is given by

⇒ Charge on capacitors (C₁, C₂ & C₃) in series

Charge on capacitor C₄ = C₄V = 4C V

Potentiometer is a long wire of uniform cross section made of manganin.

As charges and velocities are same
F=q(V×B)
So having the same magnitude of charge and same velocity, they'll experience the same magnitude of force.

Explanation : In this case we would be obtaining electrical energy continuously without doing any work.

Explanation:Doping is the process of adding impurities to intrinsic semiconductors to alter their properties. Normally Trivalent and Pentavalent elements are used to dope Silicon and Germanium. When an intrinsic semiconductor is doped with Trivalent impurity it becomes a P-Type semiconductor.

In case of negative or fractional power, expansion (1+x)^n is valid only when |x| < 1
(6 - 3x)^-1/2
= (6^-1/2 (1 - x/2)^-1/2)
So, this equation exists only when |x/2| < 1
|x| < 2

x² + y² - 4x - 6y + 4 = 0

lim(h → 0) [sin²(x+h) - sin²x]/h
l = lim(h→0) = [2sin(x+h)cos(x+h)]/1
{As we know that sin2x = 2sinxcosx
= sin2x

 ∫(π/8 to π/4)1/(sin²x cos²x)
= ∫(π/8 to π/4)(sin²x + cos^2x)/(sin²x cos²x) dx
= ∫(π/8 to π/4)(1/cos²x +1/sin²x) dx
= ∫(π/8 to π/4)(sec² x dx + cosec² x dx)
= [tan x - cot x](π/8 to π/4) + c
= [tan(π/8) - tan(π/4)] - [cot((π/8) - cot(π/4)]
= ((2)^½ +1  - 1) - (1/(2)^½ +1 - 1)
= 2

Both  y² = x³ and |y| = 2x are symmetric about y – axis and on solving them we get :

A vector whose magnitude (i.e., length) is equal to 1 is called a unit vector. There are exactly two unit vectors in any given direction and one is the negative of the other.

Flagitious : Criminal.
Innocent : Not guilty of a crime or offence.
Vapid : Offering nothing that is stimulating or challenging.
Ignorant : Lacking knowledge or awareness in general.
Frivolous : Not having any serious purpose or value.

Antonym of Flagitious is Innocent.

This statement is wrong: He couldn't but help

Correct Statement will be: He couldn't help

This statement is wrong: If you will ask him

Correct Statement will be: If you ask him

stew in his own juice: to think about or suffer the results of your own actions.

Hence, the correct answer is option d i.e. Suffer for his own act.

According to the given context of the sentence, it is regarding the fact that the delivery partners need to be aware of the practical nature of the job and they join the workforce once they accept the same. That is why it is made a point to them to understand what they have to do and then only they are allowed to enter the workforce. Among the given options, the words in Option D give us the correct pair of words that will fit in the given blanks. Other words do not fit in the blanks and can be eliminated.

This makes Option D the correct choice among the given options.

According to the given context of the sentence, it is regarding the fact that the present phase would come with another phase of weak monsoon during which the rains are within the foothills of the Himalayas. It is stated that the present phase would be followed by a weak phase of monsoon during which the rains get confined to the hills. Coming to the given options, we can only choose Option D since it provides us the correct implication of the given sentence in both the cases. Other words are irrelevant in the context of the sentence.

This makes Option D the correct choice among the given options.

Sentence A is about 17th-century Amsterdam, and how it was a common for guilds to commission portraits of themselves "in their uniforms, holding weapons". D, on the other hand, talks of a famous painting by Rembrandt, called The Night Watch. Now, it is clear that Rembrandt's painting is the main focus of the paragraph, as the rest of the sentences relate to the painting. So, D is likely to be the first sentence of the paragraph.

C begins with "its status and...". The pronoun 'its' here refers to the painting. As D is the only sentence with the painting as the subject, C follows immediately after D.

C states that the reason why the painting became critically acclaimed had nothing to do with it being a painting of a civic guard group. Sentence A explains why: it was common for guilds to commission portraits of themselves in 17th-century Amsterdam. So, A follows C.

Finally, B follows A, explaining how Rembrandt transformed a commonplace commission into a masterpiece.

So, DCAB is the right order.

The question is " Arrange the sentences in the correct order "
The order is DCAB

Hence, the answer is DCAB
Choice D is the correct answer.

Refer to, “The BIS, which sets the quality regulations for various products from gold to bottled water, on Friday called a meeting of industry bodies to “persuade them to be part of the process and give their inputs.”

It is clear from the above passage that the Bureau of Indian Standards wants the industry bodies to be part of the process of standardization drive to be launched by the organization regarding the services sectors. The organization wants the industry bodies to share their views regarding the benchmark that will be created by the BIS.

Among the given options, statements B and C are incorrect since they are about asking the industry bodies to take care of the customer complaints in any way possible whereas the passage is about the BIS developing new benchmark for standards. Statement D is also not correct since it is completely irrelevant in the given context.

Only statement A implies the appeal that was made by the BIS to the industry bodies.

This makes option A the correct choice among the given options.

O⁺²Q^-4M⁺⁶S, U⁺⁶A^-4W⁺²Y, N⁺²P^-4L⁺⁶R, B⁺²D^-4Z⁺⁶F.

Except UAWY, all other groups follow similar pattern.

Total cost = 360 × 0.78 + 14 + 13 + 5 = Rs. 312.80
He needs to sell 353 eggs for 312.8 + 70 = Rs. 382.8.
Thus, price of one egg = Rs. 1.08

Diameter of the hemispherical cup = 14 m
Therefore, radius of the hemispherical cup = 7 m
We know that,
Volume of the hemisphere 
Volume of sphere 
Let r be the radius of a stone.
According to the question,
350 × volume of stone = volume of hemispherical cup

700r³ = (7)³
r³ = 0.49

Therefore, radius is 0.79 m.
