Question 41

DDA MTS 2025• English Language and Comprehension

Read the given passage carefully and answer the questions that follow.

The topic of renewable energy is becoming increasingly important as concerns about climate change and the depletion of non-renewable resources continue to grow. Renewable energy sources, such as solar and wind power, have the potential to provide a clean and sustainable source of power for the world's growing population. One of the major advantages of renewable energy is that it is not limited by the same supply constraints as fossil fuels. Unlike oil, coal, and natural gas, which are finite resources that will eventually run out, renewable energy sources like solar and wind power will never run out. Additionally, renewable energy sources do not produce the greenhouse gases that are responsible for climate change, making them a much more environmentally friendly option. Despite the clear benefits of renewable energy, there are still significant challenges that need to be overcome in order for it to become a viable alternative to fossil fuels. One of the main challenges is the cost of renewable energy, which is currently higher than traditional fossil fuels. However, as technology continues to improve and economies of scale are achieved, the cost of renewable energy is expected to decrease. Another challenge is the need for reliable and efficient energy storage solutions, which are essential for the widespread adoption of renewable energy. Without effective energy storage solutions, renewable energy sources like solar and wind power can only be used when the sun is shining or the wind is blowing, which greatly limits their overall usefulness. Overall, renewable energy has the potential to play a critical role in addressing the world’s energy needs and reducing dependence on fossil fuels. While challenges remain, with continued research and development, renewable energy is likely to become increasingly viable and important in the coming years.

 What is the main advantage of renewable energy over fossil fuels?

  1. AOption (a)

     It is cheaper than traditional fossil fuels.

  2. BOption (b)

     It produces the greenhouse gases that are responsible for climate change. 

  3. COption (c)

     It is not limited by the same supply constraints as fossil fuels. 

  4. DOption (d)

    The renewable energy sources will eventually run out

View answer & explanation

Correct answer

Answer: (c)C.

Question 48

DDA MTS 2025• General Awareness

The kinetic energy of a particle depends on which of the following?

  1. AOption (a)

    Both mass and velocity of the particle

  2. BOption (b)

    Both mass and acceleration of the particle

  3. COption (c)

    Only velocity of the particle

  4. DOption (d)

    Only mass of the particle

View answer & explanation

Correct answer

Answer: (a)A.

Both mass and velocity of the particle

Why this answer is correct

The correct answer is Both mass and velocity of the particle.

Key Points

  • Kinetic Energy is the energy possessed by a particle due to its motion. It is mathematically defined as K.E. = 1/2 mv², where m is the mass of the particle and v is its velocity.
  • The formula clearly shows that kinetic energy depends on both the mass and the velocity of the particle. Hence, the correct answer is related to these two parameters.
  • If the mass of the particle increases, the kinetic energy increases proportionally. For example, doubling the mass doubles the kinetic energy.
  • The velocity of the particle has a more significant impact because kinetic energy is directly proportional to the square of velocity (v²). For instance, doubling the velocity increases the kinetic energy by four times.
  • Other factors such as acceleration or force are not directly involved in determining the kinetic energy of a particle, as kinetic energy is solely a function of mass and velocity.

Additional Information

  • Mass:
  • The mass of an object is a measure of its inertia, representing the amount of matter it contains. In the context of kinetic energy, larger mass results in greater energy for the same velocity.
  • For instance, a truck moving at a certain velocity has significantly more kinetic energy than a bicycle moving at the same velocity due to its larger mass.
  • Velocity:
  • Velocity is the speed of an object in a specific direction. Kinetic energy depends heavily on velocity as it is proportional to the square of velocity (v²).
  • For example, increasing the velocity of a car from 20 m/s to 40 m/s quadruples its kinetic energy.
  • Applications of Kinetic Energy:
  • Kinetic energy is a fundamental concept in physics and engineering. It is utilized in designing vehicles, machinery, and energy systems.
  • Examples include wind turbines where the kinetic energy of moving air is converted into electrical energy.
  • Important Points:
  • Kinetic energy does not depend on acceleration or force directly. These factors influence velocity, which in turn impacts kinetic energy.
  • It is a scalar quantity, meaning it has magnitude but no direction.

Question 49

DDA MTS 2025• General Awareness

Which of the following common phenomenon is an example of oxidation reaction?

  1. AOption (a)

    Souring of curd

  2. BOption (b)

    Cooking of Food

  3. COption (c)

    Rusting of iron

  4. DOption (d)

    Composting

View answer & explanation

Correct answer

Answer: (c)C.

Rusting of iron

Why this answer is correct

Rusting of iron is an example of an oxidation reaction.

Key Points

  • Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen.
  • The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.
  • Iron + water + oxygen → hydrated iron(III) oxide
  • Galvanizing is a method of rust prevention
  • The iron or steel object is coated in a thin layer of zinc.
  • This stops oxygen and water reaching the metal underneath and prevents its corrosion.
