The question asks to identify the main thinking part of the human brain. This requires knowledge of the major divisions of the brain and their primary functions.
Correct Option: C) Fore-brain
Select the option that represents the number of triangles in the given figure.
To determine the number of triangles in the given figure, we need to identify all possible combinations of lines that form triangles.
Thus, the total number of triangles is \(6 + 4 = 10\).
Correct Option: C) 10
The question asks to identify the scientist who formulated the law describing the force between two charged particles. This refers to Coulomb's Law, a fundamental principle in electrostatics.
Correct Option: B) Charles Coulomb is credited with formulating the law that governs the force of attraction/repulsion between two charged particles, known as Coulomb's Law.
To find the square root of 4624, we can use a few methods. One common method is the estimation method combined with checking the last digit. We can also use the long division method for square roots or simply test the given options by squaring them.
B) 68 is the correct option because \(68 \times 68 = 4624\).
The question asks about the physical property of sound that determines its pitch. We need to understand the definitions of pitch, amplitude, timbre, wavelength, and frequency in the context of sound waves.
Correct Option: D) frequency
Pitch is the characteristic of a sound that determines how high or low it is. It is directly proportional to the frequency of the sound wave. A higher frequency means a higher pitch, and a lower frequency means a lower pitch.
The question asks to identify the Indian stock exchange that was planning its own Initial Public Offering (IPO) as of 2018. This requires knowledge of significant financial events related to major Indian stock exchanges around that time.
Correct Option: C) The National Stock Exchange (NSE) was indeed planning to launch its own Initial Public Offering (IPO) as of 2018. Although it faced several delays due to regulatory issues and investigations, the intent and active planning for an IPO were prominent during that period. The NSE filed its draft red herring prospectus (DRHP) in December 2016 and was working towards its listing in 2018 and subsequent years.
Pipes A, B and C are attached to an empty cistern. While the first two can fill the cistern in 4 and 10 hours, respectively, the third can drain the cistern, when filled, in 6 hours. If all the three pipes are opened simultaneously when the cistern is three-fifths full, how many hours will be needed to fill the cistern?
\( \frac{36}{11} \)
\( \frac{24}{11} \)
\( \frac{48}{11} \)
\( \frac{60}{11} \)
This problem involves calculating the combined work rate of pipes filling and draining a cistern. We will determine the individual filling/draining rates, then the net rate when all pipes are open. Finally, we'll calculate the time needed to fill the remaining portion of the cistern.
To sum these fractions, find a common denominator, which is 60:
\[ \text{Net Rate} = \frac{15}{60} + \frac{6}{60} - \frac{10}{60} \]\[ \text{Net Rate} = \frac{15 + 6 - 10}{60} = \frac{21 - 10}{60} = \frac{11}{60} \text{ cistern/hour} \]This question tests general knowledge about famous sportspersons and their autobiographies. To answer correctly, one needs to recall which athlete is associated with the book 'Ace Against Odds'.
Correct Option: B) Sania Mirza
'Ace Against Odds' is the autobiography of Indian professional tennis player Sania Mirza. The book chronicles her journey to becoming a professional tennis player, her struggles, achievements, and personal life. It was co-authored with her father Imran Mirza and journalist Shivani Gupta and was released in July 2016.
To solve this problem, we need to first calculate the values of A and B separately using the given expressions. Then, we will subtract the value of B from the value of A to find the final result.
Given the expression for A:
\[ A = (-14 + 4) \]Given the expression for B:
\[ B = 4 - 14 \]Now, substitute the calculated values of A and B into the expression \(A - B\):
\[ A - B = (-10) - (-10) \]A) The final calculated value of \(A - B\) is 0. Therefore, option A is correct.
This question tests logical reasoning and understanding of implicit assumptions. An assumption is something taken for granted or accepted as true without proof. We need to evaluate each given assumption to see if it is necessarily implied by the argument.
B) Only assumption 1 follows. This is correct because the sequence of days (Sunday followed by Monday) is a universally accepted fact, making "Tomorrow is Monday" a necessary implication of "Today is Sunday."
