The question asks for the symbol of the unit of atomic mass. We need to identify the standard symbol used in chemistry and physics for atomic mass units.
Correct Option: A) u is the internationally recognized symbol for the unified atomic mass unit, which is the unit of atomic mass.
The question asks to identify the specific model of transport aircraft that was formally inducted into the Indian Air Force (IAF) in 2023. This requires knowledge of recent defense acquisitions and inductions by the IAF.
C) C-295 MW: The Airbus C295 MW transport aircraft was indeed formally inducted into the Indian Air Force in 2023. This is a medium transport aircraft designed for various missions, including tactical transport of troops and cargo, paratrooping, and medical evacuation.
The question asks to identify an example of an emulsion from the given options. To answer this, we need to understand the definition of an emulsion and then classify each option based on its physical state and composition.
Correct Option: B) Face cream is an emulsion because it consists of fine droplets of one liquid (e.g., oil) dispersed in another immiscible liquid (e.g., water), often stabilized by emulsifiers.
The problem asks us to identify a triad that follows the same pattern as two given triads. We need to analyze the letter sequences in the given triads to find the underlying rule, which typically involves positional differences of letters in the English alphabet.
This pattern seems complex. Let's re-evaluate by looking at the differences within each pair and the progression of the first and second letters separately.
The pattern for the first letters is consistent (+2). The pattern for the second letters is +2, then +8. This is not a simple, consistent pattern across all letters.
Let's re-examine the differences within each pair:
This also doesn't show a clear pattern for the third pair.
Let's consider the difference between the second letter of a pair and the first letter of the next pair:
This is a consistent pattern! Also, let's look at the difference between the two letters within each pair:
The pattern is: The difference between the two letters in the first two pairs is 5. The difference between the second letter of a pair and the first letter of the next pair is 7. The difference between the two letters in the third pair is 1.
This triad perfectly matches the pattern identified from the first triad:
All conditions of the pattern are met by option B.
To find the average speed, we need to calculate the total distance traveled and the total time taken. The average speed is then the total distance divided by the total time.
The car travels 80 km at a speed of 20 km/h.
\[ \text{Time}_1 = \frac{\text{Distance}_1}{\text{Speed}_1} = \frac{80\text{ km}}{20\text{ km/h}} = 4\text{ hours} \]The car travels 30 km at a speed of 30 km/h.
\[ \text{Time}_2 = \frac{\text{Distance}_2}{\text{Speed}_2} = \frac{30\text{ km}}{30\text{ km/h}} = 1\text{ hour} \]The total distance is the sum of the distances of the two parts of the journey.
\[ \text{Total Distance} = \text{Distance}_1 + \text{Distance}_2 = 80\text{ km} + 30\text{ km} = 110\text{ km} \]The total time is the sum of the times taken for the two parts of the journey.
\[ \text{Total Time} = \text{Time}_1 + \text{Time}_2 = 4\text{ hours} + 1\text{ hour} = 5\text{ hours} \]Average speed is total distance divided by total time.
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{110\text{ km}}{5\text{ hours}} = 22\text{ km/h} \]D) 22 km/h is the correct average speed calculated by dividing the total distance by the total time.
The question asks about the primary function of xylem in plants. To answer this, we need to recall the roles of the different vascular tissues in plants.
Correct Option: C) Conduction of water and minerals
Xylem is the primary vascular tissue responsible for transporting water and dissolved mineral nutrients from the roots upwards to all other parts of the plant. This is a fundamental process for plant survival.
The question asks about the product formed when carbon, in any of its allotropic forms, burns in oxygen. This is a fundamental chemical reaction involving the combustion of carbon.
Correct Option: B) carbon dioxide
When carbon, in any of its allotropic forms (like diamond, graphite, or charcoal), burns in a sufficient supply of oxygen, it undergoes complete combustion to produce carbon dioxide (\(CO_2\)).
The problem requires us to perform two transformations on the letters of the word "TEACHING". First, each vowel is changed to the letter following it, and each consonant is changed to the letter following it. Second, the resulting letters are arranged in alphabetical order. Finally, we need to identify the fourth letter from the right in this new arrangement.
Each vowel is changed to the letter following it, and each consonant is changed to the letter following it.
The new set of letters is: U, F, B, D, I, J, O, H.
B, D, F, H, I, J, O, U
Counting from the right: U (1st), O (2nd), J (3rd), I (4th).
B) The fourth letter from the right in the alphabetically arranged new set of letters (B, D, F, H, I, J, O, U) is I.
To find the current drawn in a circuit, we use the fundamental definition of electric current, which is the rate of flow of electric charge. The formula for current relates charge and time.
Thus, the current drawn in the circuit is 2 Amperes.
D) 2 A is correct because, according to the formula \(I = Q/t\), substituting \(Q = 100 \text{ C}\) and \(t = 50 \text{ s}\) gives \(I = 100/50 = 2 \text{ A}\).
