How many sectors are there in the following figure?
To determine the number of sectors in the given figure, we need to count the distinct regions formed by the lines and circles.
Correct Option: D) 20
The question asks about the party that won the highest number of seats in the Manipur Legislative Assembly Elections held in 2017. To answer this, one needs to recall or know the results of those specific elections.
Correct Option: D) Indian National Congress
The Indian National Congress won 28 seats, making it the single largest party in the 2017 Manipur Legislative Assembly Elections.
Select the term that is related to the third term in the same way that the second term relates to the first term.
Wrist : Watch :: Finger :?
This is an analogy question. We need to identify the relationship between the first pair of words (Wrist : Watch) and then apply the same relationship to the third word (Finger) to find the missing term.
Correct Option: A) Ring
To find the next term in the series, we need to identify the pattern or the rule governing the sequence of numbers. We will look at the differences between consecutive terms.
Therefore, the next term in the series is 63.
Correct Option: C) 63
The height and the slant height of a right circular cone are given as 3\(\sqrt{23}\) cm and 16 cm respectively. Approximating π by \( \frac{22}{7} \), find the curved surface area of the said cone.
To find the curved surface area of a right circular cone, we need its radius and slant height. The problem provides the height and slant height. We can use the Pythagorean theorem to find the radius, and then apply the formula for the curved surface area.
In a right circular cone, the height, radius, and slant height form a right-angled triangle. By the Pythagorean theorem:
\[ l^2 = r^2 + h^2 \]Substitute the given values:
\[ 16^2 = r^2 + (3\sqrt{23})^2 \] \[ 256 = r^2 + (9 \times 23) \] \[ 256 = r^2 + 207 \]Now, solve for \(r^2\):
\[ r^2 = 256 - 207 \] \[ r^2 = 49 \]Take the square root to find \(r\):
\[ r = \sqrt{49} \] \[ r = 7 \text{ cm} \]The formula for the curved surface area of a cone is:
\[ \text{CSA} = \pi r l \]Substitute the values of \(\pi\), \(r\), and \(l\):
\[ \text{CSA} = \frac{22}{7} \times 7 \times 16 \]Cancel out the 7s:
\[ \text{CSA} = 22 \times 16 \] \[ \text{CSA} = 352 \text{ cm}^2 \]Correct Option: C) 352 cm²
The question asks to identify the statement that is NOT true about diffusion. We need to evaluate each option based on the principles of diffusion in chemistry and physics.
C) Rate of diffusion of gases depends on their volume. This statement is incorrect. The rate of diffusion of a gas primarily depends on its molar mass (inversely proportional to the square root of molar mass, according to Graham's Law) and temperature. The volume of the gas sample does not directly determine its rate of diffusion.
The question asks for the specific process where a metal is degraded by its surroundings, such as moisture and acids. We need to identify the correct chemical term for this phenomenon from the given options.
Correct Option: B) Corrosion is the process in which a metal is attacked by substances around it, such as moisture, acids, or other chemicals, leading to its gradual deterioration.
The question asks to identify the recipient of the National Design Award in December 2017. This is a factual recall question related to awards and honors, which are common in competitive exams.
A) G. Satheesh Reddy was conferred with the National Design Award in December 2017 by the Indian National Academy of Engineering (INAE) for his outstanding contributions to the field of design, particularly in missile systems and aerospace technology.
The question asks for the definition of power. Power is a fundamental concept in physics that describes how quickly work is done or energy is transferred. We need to identify the option that accurately reflects this definition.
Correct Option: A) Rate of doing work or rate of transfer of energy
The question asks for the year in which the Jallianwala Bagh Massacre took place. This is a direct factual recall question from modern Indian history.
Correct Option: C) 1919
