What is the directional growth movement of a plant part in response to the touch of an object called ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 15
Thigmotropism

  • Definition: Thigmotropism is the directional growth movement of a plant part in response to the touch of an object.

  • Mechanism: When a plant part comes into contact with an object, it triggers a response in the plant cells, causing them to grow in a specific direction.

RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 16

If the potential difference across an electric bulb is 4.6 V and the current flowing through it is 0.25A what is the resistance of the bulb ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 16
Given Data:

  • Potential difference (V) = 4.6 V

  • Current (I) = 0.25 A


Formula:

  • Resistance (R) = V / I


Calculation:

  • Substitute the given values into the formula: R = 4.6 V / 0.25 A = 18.4 Ω


Answer:

  • The resistance of the bulb is 18.4 Ω


Detailed Explanation:

  • When an electric current flows through a resistor, the voltage across the resistor is directly proportional to the current passing through it.

  • Ohm's Law states that resistance is equal to the voltage across the resistor divided by the current flowing through it.

  • In this case, the potential difference across the bulb is 4.6 V and the current flowing through it is 0.25 A.

  • By applying Ohm's Law, we can calculate the resistance of the bulb which comes out to be 18.4 Ω.

RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 17

A ray of light hits a plane mirror at 60° from the normal What is the angle between the reflected ray and the surface of the mirror ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 17
Explanation:

  • Angle of incidence: The angle at which the light ray hits the mirror is 60° from the normal.

  • Angle of reflection: According to the law of reflection, the angle of reflection is equal to the angle of incidence. So, the angle of reflection is also 60°.

  • Angle between reflected ray and mirror surface: The angle between the reflected ray and the surface of the mirror can be calculated by subtracting the angle of reflection from 90° (since the angle between a ray and a surface is always measured from the normal).

  • 90° - 60° = 30°


Therefore, the angle between the reflected ray and the surface of the mirror is 30° from the mirror. So, the correct answer is D: 30° from mirror.

What is the name of the mode of reproduction by which the offspring arises from a single parent and inherits the genes of that parent only ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 18
Asexual Reproduction

  • Definition: Asexual reproduction is a mode of reproduction in which offspring arise from a single parent and inherit the genes of that parent only.

  • Process: In asexual reproduction, there is no fusion of gametes from two parents. The offspring is genetically identical to the parent.

  • Types: Asexual reproduction can occur through various methods such as binary fission, budding, fragmentation, and spore formation.

  • Advantages: Asexual reproduction is efficient in terms of energy and time as it does not require finding a mate or undergoing complex mating rituals.

  • Disadvantages: One of the main disadvantages of asexual reproduction is the lack of genetic diversity, which can make populations more susceptible to diseases and environmental changes.

RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 19

If a charge of 15.0 C flows through a wire and the amount of electrical energy converted into heat is 1.5 J what is the potential difference across the ends of the wire ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 19





  • Given:


    • Charge (Q) = 15.0 C

    • Electrical energy converted into heat (W) = 1.5 J




  • Formula:


    • The electrical energy (W) converted into heat can be calculated using the formula:
      W = Q * V

    • Where: W = Electrical energy converted into heat (in Joules)
      Q = Charge (in Coulombs)
      V = Potential difference (in Volts)




  • Calculation:


    • Given: W = 1.5 J, Q = 15.0 C

    • Using the formula W = Q * V, we can calculate the potential difference V

    • 1.5 J = 15.0 C * V

    • V = 1.5 J / 15.0 C = 0.1 V




  • Conclusion:


    • The potential difference across the ends of the wire is 0.1 V


RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 20

When a beam of light (wavelength=450nm) originally traveling in air enters a piece of glass (index of refraction 1.50) what will happen to its frequency 

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 20
Explanation:

  • Frequency of light: Frequency of light is a property that remains constant as it travels from one medium to another.

  • Wavelength of light: When light enters a medium with a different refractive index, its speed changes, and therefore its wavelength changes. However, the frequency remains constant.

  • Refractive index of glass: Glass has a refractive index of 1.50, which means light will slow down when it enters glass.

  • Relation between speed, wavelength, and frequency: Speed of light = Wavelength x Frequency. Since the speed of light changes in glass, the wavelength changes accordingly to maintain the constant frequency.

  • Conclusion: The frequency of light remains the same when it enters a different medium such as glass, only the speed and wavelength change.

RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 23

If light enters an equilateral glass prism (n=1.50) with an angle of incidence of 45 degree what is the angle of refraction as the beam emerges from the prism ?Note that an equilateral triangle has three 60° angles.

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 23
Given information:
- Angle of incidence = 45°
- Refractive index of glass prism = 1.50
- Equilateral prism has 60° angles


  • Calculate the angle of refraction using Snell's Law: n1*sin(theta1) = n2*sin(theta2)

  • Since the prism is equilateral, the angle of refraction is also 45° (60° - 45° = 15°)

  • Therefore, the angle of refraction as the beam emerges from the prism is 45°


Conclusion:
- The angle of refraction as the beam emerges from the prism is 45°, which is the same as the angle of incidence.
RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 24

When a current carrying conductor is placed above a magnetic needle what is the maximum deflection that can be produced ?

Detailed Solution for RRB NTPC Previous Year Paper (Allahabad) - 2013 - Question 24
Maximum Deflection Produced by a Current Carrying Conductor Above a Magnetic Needle

  • Explanation:


When a current carrying conductor is placed above a magnetic needle, a magnetic field is generated around the conductor. This magnetic field interacts with the magnetic field of the needle, causing the needle to deflect.



  • Maximum Deflection:


The maximum deflection that can be produced when a current carrying conductor is placed above a magnetic needle is 90°. This is because the magnetic field generated by the current carrying conductor interacts with the magnetic field of the needle at an angle of 90°, causing the needle to deflect to its maximum extent.



  • Factors Affecting Deflection:


The amount of deflection can be influenced by factors such as the strength of the current flowing through the conductor, the distance between the conductor and the needle, and the orientation of the conductor relative to the needle.



  • Conclusion:


Therefore, the maximum deflection that can be produced when a current carrying conductor is placed above a magnetic needle is 90°.
