Question Discussion & Solution

The correct answer is Concave lens.

Key Points

• To treat the eye disease known as myopia or nearsightedness we use the Concave Lens.
• A concave lens is a category of lens that deviates a straight light beam coming from the origin to a diminished, upright, virtual image.
• It can construct both real and virtual images.
• The convex lens is a lens that tends to meet at a point of rays of light that convey parallel to its principal axis which is comparatively thick across the middle and thin at the lower and upper edges.
• A convex lens is used in cameras, correction of Hyperopia, etc.
• Bifocal lenses hold two different prescriptions, an upper part to allow for distance vision and an additional power on the bottom part of the lens to help in close-up focus.
• A bifocal lens is used in people suffering from presbyopia, myopia, hyperopia, and astigmatism.
• The result is eyesight lucidity at both distance and near with one pair of glasses.
• A Compound lens is simple lenses made on a general axis usually in close proximity and often cemented with each other.

Additional Information

In this question shows that Ear, Eyes and Nose present outer part of the body but Liver present inner part of the body.

Hence, option 4 is the correct answer.

Concept:

​Simple Pendulum:

• A simple pendulum consists of a small metallic ball or a piece of stone suspended from a rigid stand by a thread.
  The metallic ball is called Bob.
• A pendulum swings from one extreme position to another and comes back to the same position, this completes one oscillation. 
• One oscillation can also be defined as the pendulum starting from the mean position, going to one extreme, and coming back to the same mean position. 
• The time duration to compete for one oscillation is called time period and the is reciprocal of time period is frequency. 
• Frequency: The number of oscillations per unit time is called frequency. 

\(frequncy =\frac{Oscillation}{Time}\)

Calculation:

Given that : Frequency = 2 hz and time = 16 sec.

In a sec pendulum completes 2 oscillations per second.

⇒ Oscillations = Frequency × time

⇒ Oscillations = 2×16

⇒ Oscillations = 32

Additional Information

The time period of a simple pendulum depends upon on the length of the string and acceleration due to gravity.

\(T = 2 \pi \sqrt{\frac{l}{g}}\)

l is length, g is acceleration due to gravity. 

The correct answer is binary.

Key Points

• Binary language is used by computers to process data.
• Binary code was invented by Gottfried Leibniz.
• A binary code is a two-symbol system that represents text, computer processor instructions, or any other data.
• The binary number system's "0" and "1" are frequently utilized as the two-symbol system.
• Each character, instruction, or other object is assigned a pattern of binary digits, commonly known as bits, by the binary code.

• IPC Section 376 A Whoever commits an offense rape(under section 376) and in the course of such commission inflicts an injury which causes the death of the woman or causes the woman to be in a persistent vegetative state.

• Law/Act	Description
  IPC Section 376	Whoever commits rape, shall be punished with rigorous imprisonment of either description for a term which shall not be less than ten years, but which may extend to imprisonment for life, and shall also be liable to fine. Whoever being a police officer, public servant, member of the armed forces, the management or on the staff of a jail, the management or on the staff of a hospital, being a relative, guardian or teacher of, or a person in a position of trust or authority towards the woman, commits rape shall be punished with rigorous imprisonment for a term which shall not be less than ten years, but which may extend to imprisonment for life, which shall mean imprisonment for the remainder of that person’s natural life, and shall also be liable to fine. Whoever commits rape on a woman under sixteen years of age shall be punished with rigorous imprisonment for a term which shall not be less than twenty years, but which may extend to imprisonment for life, which shall mean imprisonment for the remainder of that person’s natural life, and shall also be liable to fine
  IPC Section 376 A	Whoever commits an offense punishable under sub-section (1) or sub-section (2) of section 376 and in the course of such commission inflicts an injury which causes the death of the woman or causes the woman to be in a persistent vegetative state, shall be punished with rigorous imprisonment for a term which shall not be less than twenty years, but which may extend to imprisonment for life, which shall mean imprisonment for the remainder of that person’s natural life, or with death.
  IPC Section 376 B	Whoever has sexual intercourse with his own wife, who is living separately, whether under a decree of separation or otherwise, without her consent, shall be punished with imprisonment of either description for a term which shall not be less than two years but which may extend to seven years, and shall also be liable to fine.
  IPC Section 376 C	Whoever is in a position of authority or in a fiduciary relationship; or a public servant; or superintendent or manager of a jail, remand home or another place of custody established by or under any law for the time being in force, or a women’s or children’s institution; or on the management of a hospital or being on the staff of a hospital, abuses such position or fiduciary relationship to induce or seduce any woman either in his custody or under his charge or present in the premises to have sexual intercourse with him, such sexual intercourse not amounting to the offence of rape, shall be punished with rigorous imprisonment of either description for a term which shall not be less than 5 years, but which may extend to ten years, and shall also be liable to fine.
  IPC Section 376 D	Where a woman is raped by one or more persons constituting a group or acting in furtherance of a common intention, each of those persons1 shall be deemed to have committed the offence of rape and shall be punished with rigorous imprisonment for a term which shall not be less than twenty years, but which may extend to life which shall mean imprisonment for the remainder of that person’s natural life, and with fine
  IPC Section 376 E	Whoever has been previously convicted of an offense punishable under section 376 or section 376A or section1 376AB or section 376D or section 376DA or section 376DB and is subsequently convicted of an offense punishable under any of the said sections shall be punished with imprisonment for life which shall mean imprisonment for the remainder of that person’s natural life, or with death.
