The question asks about the type of image formed by a convex mirror when an object is placed in front of it. We need to recall the image formation properties of convex mirrors.
B) Virtual, erect, small image between pole and focus. This accurately describes the image formed by a convex mirror for any real object placed in front of it.
This question asks us to identify implicit assumptions based on a given statement. An assumption is something taken for granted or supposed to be true without proof. We need to analyze the statement and determine which of the given assumptions logically follows from it, meaning the statement wouldn't make sense without that assumption being true.
D) Only assumption II is implicit.
The tagline "Triple your money" is designed to attract people who are looking for quick and substantial financial gains. Without the underlying desire of people to earn money fast, such an advertisement would be pointless and ineffective. Therefore, the advertisers assume that this desire exists among the target audience.
This is a syllogism problem. We need to analyze the given statements and determine which of the conclusions logically follow. We can use Venn diagrams or logical reasoning to deduce the relationships between the categories: Lawyers, Professionals, Intelligent, and Prosperous.
D) Only conclusion I follows.
The question asks for the specific property of carbon that allows its atoms to form long chains with each other. We need to identify the term that describes this self-linking capability.
D) Catenation — Catenation is the unique property of carbon atoms to link with each other through covalent bonds to form long chains, branched chains, or rings. This property is responsible for the vast number of organic compounds.
Which of the following is an inert gas group?
Alkaline metal group
16th group
Halogen group
18th or zero group
The question asks to identify the group of elements known as inert gases. This requires knowledge of the periodic table and the classification of elements based on their chemical properties and group numbers.
Correct Option: D) The 18th group, also known as the zero group, contains the noble gases (Helium, Neon, Argon, Krypton, Xenon, Radon, and Oganesson). These elements are characterized by their full outer electron shells, making them very stable and unreactive, hence the term "inert gases."
The question asks to identify the Union Ministry held by Piyush Goyal as of August 2018. This requires knowledge of the Union Council of Ministers and their portfolios during that specific period.
Correct Option: C) Railways
Read the given question and decide which of the following statement(s) is/are sufficient to answer the question.
Question:
Which is the lightest box among B1, B2 and B3? Statements:
1. B1 contains packaged food.
2. The weight of B3 is one-fourth of the weight of all the other boxes added together.
Statements 1 and 2 both are sufficient
Statement 2 alone is sufficient.
Statement 1 alone is sufficient
Statements 1 and 2 both are not sufficient.
We need to determine if the given statements provide enough information to identify the lightest box among B1, B2, and B3. We will analyze each statement individually and then combined.
Analyze Statement 1: B1 contains packaged food.
Analyze Statement 2: The weight of B3 is one-fourth of the weight of all the other boxes added together.
Analyze Statements 1 and 2 combined:
Correct Option: D) Statements 1 and 2 both are not sufficient.
The question asks to identify the state where Bhushan Power & Steel Limited's Jharsuguda unit is located. This requires knowledge of the geographical locations of major industrial units in India.
Correct Option: D) Odisha is the correct answer because Jharsuguda, where Bhushan Power & Steel Limited has a significant unit, is a city located in the state of Odisha.
A porter lifts 20 kg of goods from the ground and places it on his head 2 m above the ground. Calculate the work done by him on the goods. (g = 10 m s-2 is given)
To calculate the work done when an object is lifted, we need to consider the force applied against gravity and the vertical distance moved. The work done against gravity is equal to the change in potential energy of the object.
When an object is lifted vertically, the work done (\(W\)) against gravity is given by the formula:
\[ W = F \times h \]
Where \(F\) is the force required to lift the object, which is equal to its weight (\(mg\)).
\[ W = mgh \]
\[ W = (20 \text{ kg}) \times (10 \text{ m s}^{-2}) \times (2 \text{ m}) \]
\[ W = 200 \times 2 \]
\[ W = 400 \text{ J} \]
The SI unit of work is Joules (\(J\)).
Correct Option: B) 400 J
The question asks for the main component of Liquefied Petroleum Gas (LPG). To answer this, we need to recall the chemical composition of common fuels like LPG.
D) Butane
Butane (\(C_4H_{10}\)) is one of the primary components of LPG. In many regions, especially for domestic use, LPG is a mixture predominantly containing butane and propane. Butane has a higher energy content per unit volume than propane and is often preferred in warmer climates because its boiling point is higher, making it easier to store and transport as a liquid under lower pressure.
