Question Discussion & Solution

The correct answer is Punishment shall not be less than seven years, but which may extend to ten years, and shall also be liable to fine.

• Under Section 370, whoever commits the offence of trafficking shall be punished with rigorous imprisonment for a term which shall not be less than seven years, but which may extend to ten years, and shall also be liable to fine.

​ Important Points

•  Section 370 -
  • ​Trafficking means whoever, for the purpose of exploitation, a. recruits b. transports c.harbours, d.transfers, or e. receives, a person or persons, by-
    • ​using threats,
    • using force, or any other form of coercion,
    • by abduction,
    • by practising fraud, or deception,
    • by abuse of power,
    • by inducement, including the giving or receiving of payments or benefits, in order to achieve the consent of any person having control over the person recruited, harboured, transported, transferred, or received, commits the offence of trafficking. 
• The expression "exploitation" shall include any act of physical exploitation or any form of sexual exploitation or practices similar to slavery, servitude, or the forced removal of organs.
• The consent of the victim is immaterial in the determination of the offence of trafficking.

Concept:

• Any battery (actually it may have one or more than one cell connected in series) or cell that we use as a source of electrical energy is a galvanic cell where the chemical energy of the redox reaction is converted into electrical energy. 
• In the primary batteries, the reaction occurs only once, and after use over some time battery becomes dead and cannot be reused again.
• The most familiar example of this type is the dry cell (known as Leclanche cell after its discoverer) which is used commonly in our transistors and clocks. 
• The cell consists of a zinc container that also acts as anode and the cathode is a carbon (graphite) rod surrounded by powdered manganese dioxide and carbon.
• The space between the electrodes is filled by a moist paste of ammonium chloride (NH4Cl) and zinc chloride (ZnCl2). 

Explanation:

• The cell consists of a zinc container that acts as the anode.
• The cathode is a carbon (graphite) rod surrounded by a cathodic material powder of manganese dioxide and carbon.

So, The positive pole of the dry cell is made up of C (carbon).

Hence code for words task is “gin lin”.

CONCEPT:

Electric Charge: It is a physical property of a matter that experiences a force when placed in an electromagnetic field.

• Electric charges create electric fields.

• Two types of charges are found – 1.) Positive charge. 2.) Negative charge
• Force experienced when charge placed in the electromagnetic field is \({{F}^{\to }}=q\times {{E}^{\to }}\) where q = charge of the body (in coulomb). \({{E}^{\to }}\) = intensity of the electric field.
• SI unit of charge is Coulomb and the symbol is C. One coulomb is equal to the charge on 6.241 x 10¹⁸ protons.

Inductor: It is a passive electric component that stores energy in the form of magnetic field lines. It is a simple loop of wire.

• The inductance of the inductor could be measured by equation L = Φ / I where ϕ is magnetic flux and I is a current flowing through it.
• SI unit of inductance is Henry.
• Energy stored in Inductor U = ½ (LI²).

Capacitor: It is a device consisting of two conducting "plates" separated by an insulating material (dielectric). It stores energy in the form of an electric field with the help of an electric charge.

• The capacitance of a capacitor is measured by equation C = q /Δ v where q is charge and ∆ V is a potential difference.
• SI Unit of capacitance is Farad.
• Energy stored in Capacitor U = ½ (CV²)

Resistance: It is a measure of how the device reduces the flow of electric current, basically it opposes the flow of charges.

• Further, it states the ratio of the applied voltage to electric current flows through it.
• R = V/I [R is resistance, V is the potential difference and I is electric current].
• Also, R = ρ × (L/A) [where ρ is specific resistance of the material, l is the length of conductor and A is the cross-sectional area of the conductor].
• The unit of resistance is volt/ampere or ohm (Ω).
• It does not store energy.

Transformer: It is an electrical device that converts A/C current from one voltage to another.

EXPLANATION:

• A capacitor stores energy in the form of electrical charges and fields.
• Here, C_o = Capacitance, V = voltage, A = area of the plates, d = distance between them.

\(\Rightarrow {{C}_{o}}=\frac{{{Q}_{o}}}{V}=\frac{{{\epsilon }_{o}}A}{d}\)

Important Points

• Remember Electric field lines are stored in capacitor & magnetic field lines are stored in Inductor.

The correct answer is Energy.

• Energy can neither be created nor be destroyed.

Key Points

• First Law of Thermodynamics:
  • It is also known as the Law of Conservation of Energy and states that energy cannot be created or destroyed in an isolated system.
  • Thermodynamics was discovered by Ludwig Boltzmann.
  • Albert Einstein also said that "Energy cannot be created or destroyed. It can only be changed from one form to another."

Additional Information

• Force is that external cause which when acts on a body, changes or tries to change the initial state of the body.
  • Force = mass × acceleration
  • Its S.I. unit is Newton (kg. m s-2)
• Momentum is the property of a moving body and is defined as the product of mass and velocity of the body.
• It is a vector quantity.
  • Its SI unit is kg m/s.
• The rate of doing work is called power.
  • SI unit of power is watt or Joule Per second named as a respect to the scientist James Watt.
  • It is a scalar quantity.
