The correct answer is Both 1 and 2.

Key Points

​Rutherford’s scattering experiment:

• In this experiment, the scattering of particles is explained with the concept of coulombs interaction between the atoms.
• He shows that in the middle of the atom, highly dense particles are present in the center of the atom, which is named the nucleus.

The correct answer is ​Stagnation.

Key Points

• Stagnation
  • It is a prolonged period of little or no growth in an economy. Hence, Option A is correct.
  • Real economic growth of less than 2% annually is considered stagnation, and it is highlighted by periods of high unemployment and involuntary part-time employment. Stagnation can occur on a macroeconomic scale or a smaller scale in specific industries or companies.
  • Stagnation can occur as a temporary condition, such as a growth recession or temporary economic shock, or as part of a long-term structural condition of the economy.
  • Stagnation is a condition of slow or flat growth in an economy.
  • Stagnation often involves substantial unemployment and underemployment, as well as an economy that is generally performing below its potential.
  • Periods of stagnation can be short-lived or long-lasting and can result in a range of economic and social factors.

Additional Information

• Recession
  • It is a macroeconomic term that refers to a slowdown or a massive contraction in economic activities for a long enough period, or it can be said that when a recessionary phase sustains for long enough, it is called a recession.
• Stagflation
  • The term was coined by Iain Macleod, a Conservative Party MP in the United Kingdom, in November 1965.
  • Stagflation is said to happen when an economy faces stagnant growth as well as persistently high inflation.

  • Reflation policies can include reducing taxes, changing the money supply, and lowering interest rates.

No force acts on a current-carrying conductor when it is placed parallel to the magnetic field.
Key Points
The force on a current-carrying conductor in a magnetic field is given by F = IlB sinθ, where:

• ​F is the force on the conductor (in N).
• I is the current in the conductor (in A).
• l is the length of the conductor (in m).
• B is the magnetic field strength (in T).
• θ is the angle between the conductor and the magnetic field (in degrees).

When the conductor is parallel to the magnetic field, θ = 0° and sinθ = 0.
​Therefore, F = 0, and no force acts on the conductor.

The correct answer is ​They are gases at room temperature
Key Points

• The elements in Group 1 of the Periodic Table are known as alkali metals.
• These include elements like Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).

Properties of these elements:

A. They are good conductors of electricity - TRUE:

• alkali metals are good conductors of electricity.
• This is due to their ability to easily lose their outermost electron to form positive ions.
• The delocalized electrons are free to move, allowing electric current to pass through.

B. They are highly reactive - TRUE:

• Alkali metals are known for their high reactivity.
• This is because they have only one electron in their outermost shell, and they want to lose this electron to achieve a stable electron configuration (a full outer shell).
• This makes them highly eager to participate in chemical reactions.
• For instance, they react vigorously with water to produce hydrogen gas and alkali hydroxides.

C. They have one valence electron - TRUE:

• The defining characteristic of alkali metals is that they each have a single electron in their outermost energy level (also known as valence shell).
• This single electron is held relatively loosely because it is far from the positive charge of the nucleus, making it easy for alkali metals to lose this electron and form a positive ion.

D. They are gases at room temperature - FALSE:

• None of the alkali metals are gases at room temperature.
• They are all solid at room temperature.
• The elements that are gases at room temperature are located in the rightmost area of the Periodic Table, such as the noble gases (Group 18).

The Correct answer is Only (D).

Concept:

• The process by which organisms exchange gases between their body cells and the environment is known as respiration.
• Respiration is of two types:
• Aerobic respiration:
  • Aerobic respiration is a type of cellular respiration that occurs in the presence of oxygen and produces energy.
• Anaerobic respiration:
  • Anaerobic respiration is another type of cellular respiration that occurs in the absence of oxygen and produces energy.

Explanation:

• Sometimes when we do heavy exercise such as fast running, cycling, walking, and weightlifting we require a lot of energy to meet the energy requirement of our body, which causes an impermanent lack of oxygen in the muscle cells.
• In the absence of oxygen, our bodies perform anaerobic respiration, in which glucose in muscle cells is converted into lactic acid.
• In this process, energy is produced but in a smaller amount.
• Glucose →Lactic acid + energy (in smaller amounts)

Additional Information

• Uttarakhand CM launched “Dhami against drugs campaign.”

• Uttarakhand Chief Minister Pushkar Singh Dhami has launched the "Dhami against drugs campaign" in Dehradun, Uttarakhand.
• The campaign, organized by Bharatiya Janata Yuva Morcha Metropolitan Dehradun, is aimed at combating drug abuse in the state.
• Chief Minister Dhami also released T-shirts and posters related to the campaign during the launch event.
• He emphasized the state government's resolution to make Uttarakhand drug-free by the year 2025 and called upon the people to actively participate in achieving this goal.
• The initiative includes rapid involvement of students and colleges in the campaign to create awareness and prevent drug abuse among the youth.

The correct answer is Pupil .
Concept:

• Iris controls the size of the Pupil and the Pupil regulates the amount of light entering the human eye. It is responsible for the adjustment of the pupil according to the intensity of light received by the eye.
  • If the amount of light received by the eye is large, then the iris contracts the pupil and reduces the amount of light entering the eye.
  • If the amount of light received by the eye is small, then the iris expands the pupil so that more light may enter the eye.
• Retina: An image is formed on the retina.
• The eye lens refracts the light ray, forming an image on the retina.

​​

Explanation:
The amount of light entering the eye is controlled by the pupil.
​Different parts of the eyes and their functions are shown in the table:

Mistake Points
The iris is like a gatekeeper; it changes the size of the pupil. The pupil is the actual opening through which light enters the eye. When there's a lot of light, the iris makes the pupil smaller to let in less light. When it's dark, the iris makes the pupil bigger to let in more light.
So, while the iris controls the size of the pupil, it's the pupil that directly regulates the amount of light entering the eye.
So, Pupils directly controls the amount of light entering in human eye.

The correct answer is cyclical unemployment.

Key Points

• Unemployment occurs when there are changes to an economy’s business cycle is termed Cyclical Unemployment.
• Cyclical unemployment is termed as demand deficiency i.e. unemployment starts to rise when demand falls.
• Causes for Cyclical Unemployment
  • The decline in Demand contributes to less investment in business hence requiring fewer employees.
  • Negative multiplier effects when demand falls this affects stores, farmers manufacturing workers,s and also those investing in transporting these goods and products which results in further affecting multiple areas.
  • A bad Market Crash can cause a recession by instilling a loss of confidence in an economic decline in employers looking to hire and expand can be seen.
• Therefore, Unemployment caused by the recession of 2008-2010 is an example of Cyclical Unemployment.​

Additional Information

• Structural unemployment occurs when there is a mismatch between available jobs and available workers' talents. Many people in India struggle to find work because they lack the necessary skills, and training them is difficult due to a lack of knowledge.
• Frictional unemployment is the result of employment transitions within an economy where workers voluntarily leaving their jobs and new workers enter the workforce.
