To find the molecular mass of a compound, we need to sum the atomic masses of all the atoms present in its chemical formula. For carbon monoxide (CO), we need the atomic masses of Carbon (C) and Oxygen (O).
The molecular mass of CO is the sum of the atomic mass of Carbon and the atomic mass of Oxygen.
\[ \text{Molecular mass of CO} = \text{Atomic mass of C} + \text{Atomic mass of O} \\ \text{Molecular mass of CO} = 12 \text{ amu} + 16 \text{ amu} \\ \text{Molecular mass of CO} = 28 \text{ amu} \]Therefore, the molecular mass of CO is 28.
Correct Option: D) 28
The following pie diagram shows the revenue of the company ABC, which manufactures leather products. The total revenue of the company for the year 2015 was Rs. 36,28,000
Among the products, which product gave the major source of revenue (largest revenue making product) to the company?
To determine which product contributed the most to the company's revenue, we need to analyze the pie chart provided. Each segment represents a percentage of the total revenue.
Correct Option: D) Bags
This is a blood relations problem. We need to deduce the relationship between Brunda and Mohan based on the statements made by Keerthana. We will break down Keerthana's statement into smaller parts and build a family tree or relationship chain.
Since Mohan is Revanth's father, and Revanth is Brunda's father, Mohan is Brunda's paternal grandfather. Therefore, Brunda is Mohan's granddaughter.
Correct Option: C) Granddaughter — Based on the analysis, Brunda is the daughter of Revanth, who is the son of Mohan. Thus, Brunda is Mohan's granddaughter.
1 Newton =?
The question asks for the definition of 1 Newton in terms of fundamental SI units. This requires recalling Newton's Second Law of Motion and the SI units for mass, acceleration, and force.
C) 1 kg m s -2 is correct because 1 Newton is defined as the force required to accelerate a mass of 1 kilogram at a rate of 1 meter per second squared, according to Newton's Second Law of Motion.
Find the rotated image of the given figure.
To find the rotated image of the given figure, we need to analyze the orientation and position of the elements in the original diagram and compare them with the options provided.
Correct Option: D) The figure is rotated correctly, preserving the orientation and structure of the original design.
The question asks to identify the state that won the best tableau prize at the 2018 Indian Republic Day parade. This requires knowledge of specific events and awards related to the Republic Day celebrations of that year.
Correct Option: A) Maharashtra
Maharashtra's tableau, which showcased the coronation of Chhatrapati Shivaji Maharaj, was adjudged the best among the 14 states and Union Territories that participated in the Republic Day parade in 2018.
To solve this problem, we need to perform addition and subtraction of decimal numbers. It's often easier to group positive numbers together and negative numbers together first, then perform the final subtraction.
Identify the positive and negative numbers in the expression:
\[ 35 - 7.892 + 0.005 - 10.345 \]Sum the positive numbers:
\[ 35 + 0.005 = 35.005 \]Sum the absolute values of the negative numbers (and keep the negative sign):
\[ 7.892 + 10.345 = 18.237 \]So, the sum of negative numbers is \(-18.237\).Now, combine the sum of positive numbers and the sum of negative numbers:
\[ 35.005 - 18.237 \]Perform the subtraction:
\[ \begin{array}{r} 35.005 \ - 18.237 \ \hline 16.768 \end{array} \]C) \(16.768\) is the correct result of the calculation.
The question asks to identify the person who does NOT belong to the group. This implies that most of the options share a common characteristic, and one option deviates from it. We need to analyze the professions or fields of expertise of each individual listed.
Correct Option: B) Sania Mirza is a professional tennis player, whereas Rukmini Arundale, Birju Maharaj, and Mrinalini Sarabhai are all celebrated personalities in the field of Indian classical dance.
The difference between two fractions is \( \frac{5}{6} \). The smaller one is \( \frac{3}{4} \). What is the other fraction?
\( \frac{1}{12} \)
\( \frac{19}{24} \)
\( \frac{8}{10} \)
\( \frac{19}{12} \)
The problem states the difference between two fractions and provides the value of the smaller fraction. We need to find the other (larger) fraction. We can set up an equation where the larger fraction minus the smaller fraction equals their difference.
Let the other (larger) fraction be \( x \).
Since the difference is given, and we know the smaller fraction, the larger fraction minus the smaller fraction must equal the difference.
\[ x - \frac{3}{4} = \frac{5}{6} \]To find \( x \), add \( \frac{3}{4} \) to both sides of the equation:
\[ x = \frac{5}{6} + \frac{3}{4} \]The least common multiple (LCM) of 6 and 4 is 12.
D) \( \frac{19}{12} \) is the other fraction.
________ is the most metallic element in the fifth period
The question asks to identify the most metallic element in the fifth period of the periodic table. Metallic character generally increases down a group and decreases across a period from left to right. Therefore, the most metallic element in a given period will be found in Group 1 (alkali metals) at the beginning of that period.
Correct Option: A) Rubidium is an alkali metal (Group 1) and is the first element in the fifth period. According to the periodic trends, metallic character is highest for elements in Group 1 and decreases across the period. Therefore, Rubidium is the most metallic element in the fifth period.
