Army Cadet College (ACC) Mock Test - 9 - Army Cadet College (ACC) MCQ

As, (4)² + 3 = 19

Similarly, (7)² + 3 = 52

Given:

The side of the square = 22 cm

Formula used:

The perimeter of the square = 4 × a    (Where a = Side of the square)

The circumference of the circle = 2 × π × r     (Where r = The radius of the circle)

Calculation:

Let us assume the radius of the circle be r

⇒ The perimeter of the square = 4 × 22 = 88 cm

⇒ The circumference of the circle = 2 × π ×  r

⇒ 88 = 2 × (22/7) × r

⇒ 

⇒ r = 14 cm

∴ The required result will be 14 cm.

As short form of 'Mountain' is 'Hill' similarly 'Tank' is short form of 'River'.

From Statement I: From this statement, we get the following arrangement:

So, we get that X is 2nd to the left of Y.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II: From this statement, we get the following arrangement:

In both cases, we get X is 2nd to the left of Y.

Clearly, Statement II alone is sufficient to answer the question.

Hence, option C is the correct answer.

As 'Architect' makes 'Building' similarly 'Sculptor' makes 'Statue'.

As the sound of 'Jackal' is 'Howl' similarly the sound of 'Cow' is 'Moo'.

Given: a₂₀ - a₁₃ and d = 5
⇒ a₂₀ - a₁₃ = a + (20 - 1) d - [a + (13 - 1) d] = a + (20 - 1) x 5 - [a + (13 - 1) x 5]
⇒ a₂₀ - a₁₃ - a = a + 95 - [a + 60]
= a+95 - a - 60 = 35 

By using corresponding angle axiom to find out the relation between the alternate interior angle when a transversal two parallel lines .In fig transversal PS intersect parallel lines AB and CD at points Q and R . angle BQR = Angle QRC andAQR = angle QRD we know that angle PQA = angle QRC ……1corresponding angle axiom angle PQA = angle BQR now , from 1 and 2 you may conclude angle BQR= angle QRCsimilarly,. angle AQR= angle QRD

First hundred even natural numbers divisible by 5 are

10, 20, 30, 40, 50............1000

If last term is 1000, then sum of all these numbers can’t be 500

Therefore, A is false but R is true.

AP+PB=AB [diameter of circle]
4+16=20[diameter]
so r=AO = CO=10
so clearly PO= OA-AP=10-4=6
PO=6 OC=10 So just apply pythagoreus theorem in triangle PCO
so CP will come 8 So chord CD = 2x8 = 16

we know that the line parallel to y axis is given by x = a

x-4 = 0

x = 4
so it is a line parallel to y axis, at a distance of 4 units from it, to the right.

The main source of variation in offspring is sexual reproduction.

Sexual reproduction involves the fusion of gametes from two parents, resulting in offspring that inherit a unique combination of genetic material from both parents. This process introduces variation in several ways:

• Independent assortment of chromosomes: During meiosis, the homologous pairs of chromosomes align randomly and separate into different gametes. This leads to different combinations of genes being passed on to the offspring.



• Crossing over: Crossing over occurs during meiosis when homologous chromosomes exchange segments of genetic material. This further increases genetic diversity by shuffling genes between chromosomes.



• Random fertilization: The chance of a specific sperm fertilizing a specific egg is random, leading to a nearly infinite number of possible combinations of genetic material in offspring.



• Mutations: Mutations, which are changes in the DNA sequence, can occur spontaneously or as a result of environmental factors. These mutations can introduce new genetic variations in the offspring.

While asexual reproduction, cloning, and parthenogenesis can also produce offspring, they do not involve the combination of genetic material from two parents and therefore do not introduce as much variation as sexual reproduction.

Colloids
A colloid is a mixture in which small particles of one substance are dispersed evenly throughout another substance. The particles in a colloid are larger than those in a solution but smaller than those in a suspension. Colloids can be found in various forms, including liquids, gels, and solids.
Identifying the Colloid
To determine which of the given options is a colloid, we need to understand the characteristics of a colloid and analyze each option accordingly.
A: Aluminium paint
- Aluminium paint is a mixture of tiny aluminum particles dispersed in a liquid medium, usually oil or water.
- The aluminum particles in the paint are larger than those in a solution but smaller than those in a suspension.
- Therefore, aluminium paint is a colloid.
B: Blood
- Blood is a complex mixture of cells, proteins, and other substances suspended in plasma.
- The cells and proteins in blood are larger than those in a solution but smaller than those in a suspension.
- Therefore, blood is a colloid.
C: Milk
- Milk is a mixture of water, fats, proteins, and other substances.
- The fats and proteins in milk form small particles that are dispersed throughout the liquid.
- These particles are larger than those in a solution but smaller than those in a suspension.
- Therefore, milk is a colloid.
D: All
- Since all three options (aluminium paint, blood, and milk) meet the characteristics of a colloid, the correct answer is D: All.
Conclusion
In summary, all of the given options (aluminium paint, blood, and milk) are colloids. They are all mixtures in which small particles of one substance are dispersed evenly throughout another substance.

The term "scale" in cartography refers to the relationship between distance on the map and distance on the ground. A "small scale" map displays a larger area of land with less detail. For example, a world map is a small scale map because it shows continents and oceans with minimal detail. Conversely, a "large scale" map, like a city map, shows a smaller area with much greater detail.

The amount of energy put out by the Sun is a constant. The incoming solar radiation is known as insolation. The amount of solar energy reaching the Earth is 70 percent. The surface of the Earth absorbs 51 percent of the insolation.

Office Order dated 13-8-1990: Reservation of Seats
The office order dated 13-8-1990 regarding the reservation of seats was signed by the Joint Secretary.
Explanation:
- The office order, which pertains to the reservation of seats, was issued on 13-8-1990.
- The order was signed by a specific individual holding a designated position within the office hierarchy.
- Among the given options, the most appropriate position to sign such an order would be the Joint Secretary.
- The Joint Secretary typically holds a high-ranking position within an organization and is responsible for assisting the Secretary in carrying out administrative duties.
- Given their role in overseeing various departments and functions, the Joint Secretary would be authorized to sign an office order related to reservation of seats.
- It is important to note that the other options provided, namely the Secretary, Deputy Secretary, and Under Secretary, may also hold positions of authority within the office but are less likely to be directly responsible for signing such an order.
Therefore, the correct answer is B: Joint Secretary.

There are four main agents of erosion. Moving water, wind, gravity, and ice wear away or break up rocks, sediments, and soil from the land's surface. When these materials are deposited or dropped in new places, it is called deposition. Erosion and deposition work together.

The Earth and Venus do often get called planetary twins because:

• They are very close to being the same mass.
• Both are rocky planets, therefore they have effectively the same density and resulting very close resemblance of physical size.
• They have significant atmospheres surrounded their surfaces.
