2.Given is a question followed by two arguments numbered I and II. Read the question and decide which of the arguments is strong with respect to the question.

Question:

Should shifting agriculture be practiced?

Arguments:

I. No. It is not a worthy practice.

II. Yes. When compared to modern methods of farming, it is less expensive.

A. Only argument II is strong.

B. Only argument I is strong.

C. Neither argument I nor II is strong.

D. Either argument I or II is strong.

Solutions

Shifting agriculture has many benefits.

It helps to ensure weed control, pest control, sustainability etc. It is also effective in reducing the rate of environmental degradation.

Thus, the argument that this agricultural practice is unworthy is incorrect.

Therefore, argument 1 is not strong.

In shifting agriculture, an area of land is cleared off its vegetation by burning them and cultivated for a period of time and then abandoned. Thus, that abandoned land then gets ample time to restore its fertility naturally.

This method saves a wide range of resources and provides nutrients because a small area is usually cleared and the burned vegetation offers many nutrients eventually saving the costs involved in improving the fertility of the land.

Therefore, this method is considered less expensive compared to modern methods of farming.

The economic nature of shift farming is reason enough for it to be preferred over the conventional methods.

Thus, argument 2 is strong.

Hence, only argument 2 is strong.

3. Read the give statement(s) and conclusions carefully and select which of the conclusions logically follow(s) from the statements(s).

Statement:

Recent research says listening to specific types of frequencies have a positive effect on human brain and it aids in healing.

Conclusion:

I. Human brain responds to music.

II. Certain frequencies are used to heal diseases in human body.

A. Both the conclusions follow.

B. Neither conclusion follows.

C. Only conclusion I follows.

D. Only conclusion II follows.

Solutions

The statement only talks about specific types of frequencies.

Though music is a type of frequency, we cannot be certain that this is the type mentioned in the statement.

Therefore, the conclusion that human brain responds to music is possible but not definite.

Thus, conclusion I does not follow.

The statement says that specific type of frequencies aid in healing of problems related to human brain.

As brain is an internal organ of human body, it is safe to conclude that these frequencies are used to heal diseases in human body.

Therefore, conclusion II follows.

Hence, only conclusion II follows.

A. 5/√2

B. 2/√5

C. 3/2

D. 5/2

Solutions

As we know,

Volume of hemisphere = (2/3)πr³

Volume of cone = (1/3)πr²h

According to the question

(1/3)πr²h = (2/3)πr³

h = 2r

As we know,

l² = r² + h²

⇒ l² = r² + (2r)²

⇒ l² = 5r²

⇒ l = √5 r

Curved surface area of hemisphere = 2πr²

Curved surface area of cone = πrl = πr × (√5r) = √5r²

Required ratio = 2πr²/√5πr² = 2/√5

A. 30°

B. 45°

C. 40°

D. 35°

Solutions

Since, CBED is cyclic quadrilateral.

⇒ ∠CDE = ∠CEA

∴ ∠CEA = 80°

⇒ ∠CDE + ∠CBE = 180°

⇒ ∠CBE = 180° – 80° = 100°

In ΔCBE

∠C + ∠B + ∠E = 180

⇒ ∠C + 100° + ∠E = 180

⇒ ∠C + ∠E = 180° – 100° = 80°

⇒ ∠BCE = ∠CEB = 40°

Now

∠BEA = ∠CEA – ∠CBE

⇒ ∠BEA = 80° – 40°

⇒ ∠BEA = 40°

25. The property of metals wherein they can be beaten into thin sheets is called ________.

A. Expansion

B. Malleability

C. Ductility

D. Conduction

Solutions

The property of the metals wherein they can be beaten into thin sheets is called the Malleability.
Malleability is the ability of the material to deform under the pressure.
Malleability occurs in metal because of the metallic bonds that keep the metal in place. Metallic bonds are characterized as the sea of the electron, and electrons easily can move from atom to another, which allows the atom to slide on each other by applying the force.
Expansion- It is the action of becoming larger.
Ductility- It is the physical property of the material which is associated with the ability to be hammered thin or stretched wire without breaking.
Conduction- It is the property of the material to allow the flow of charges in the metals.

32. The diagram shows the force field produced by a current-carrying wire. Name the force field.

A. Electrostatic field

B. Magnetic field

C. Electromagnetic field

D. Static field

Solutions

CONCEPT:

Electrostatic field: Filed of lines starts from the positive charge and end at the negative charge.
- It is formed only by a charged particle, not by electric current.
Magnetic field: Magnetic field line starts from the North pole and ends at the south pole, it always makes a closed loop.
- It is formed by electric currents and magnets.
Magnetic field lines: The imaginary lines which represent the direction of the magnetic field are called magnetic field lines.
- The tangent at any point on the field lines gives the direction of the magnetic field vector at that point.
- Magnetic lines of force always emerge or start from the North Pole and terminate on the South Pole.

Electromagnetic field: It is a field that is getting produced by the accelerated charged particle.
Static field: It is a kind of field, which is getting produced by the state charge.

EXPLANATION:

From the above discussion, we can say that the magnetic field lines are produced by a current-carrying wire. So option 2 is correct.

IMPORTENT POINT

In the case of electric current, the electrons flow in the wire but there are equal and opposite charges, that is the same number of protons are there in that wire which doesn’t flow.
- That’s why the overall current-carrying wire is neutral and it can’t produce an electric field.
A charge at rest produces an electric field only.
A charge moving with a constant velocity produces both electric field as well as the magnetic field.
A charge moving with some acceleration produces electromagnetic waves/fields.

74. Newton’s second law of motion _______

A. It is also called a law of conservation of energy

B. Is also called as law of inertia

C. Describes the relationship between the forces on two interacting objects

D. Explains about change in momentum

Solutions

CONCEPT:Newton’s First law:

A body continues to be in its state of rest or of uniform motion along a straight line unless it is acted upon by some external force to change the state.If no net force acts on a body, then the velocity of the body cannot change i.e. the body cannot accelerate.Newton’s first law defines inertia and is rightly called the law of inertia.

Newton’s Second Law:

The rate of change of linear momentum of a body is directly proportional to the external force applied on the body and this change takes place always in the direction of the applied force.

Where F = Force, m = mass and a = acceleration

Newton’s Third Law:

To every action, there is always an equal (in magnitude) and opposite (in direction) reaction.When a body exerts a force on any other body, the second body also exerts an equal and opposite force on the first.Forces in nature always occur in pairs. A single isolated force is not possible.

EXPLANATION:

From above it is clear that Newton’s second law of motion explains about change in momentum. Therefore option 4 is correct

B. 200000 J – 500000 J

C. 20000 J – 50000 J

D. 2000 J – 5000 J

Solutions

As per the given question,

We know that the average weight of the man is between 45-80 kg,

Hence the average weight of the athlete = 50 kg

Distance covered by man = 100 m

Time is taken by the athlete to cover 100 m = 10 sec

Let the initial speed of the athlete = 0 m/ sec

If he runs with constant velocity then v = 10 m/sec then kinetic energy = ½ mv² = 50 × 10 × 10/2 = 2500J

Hence option 4 (2000 J – 5000 J) is the correct answer.

D. 84, 168 and 56

Solutions

A and B can complete a task in = 70 days

B and C can complete the task in = 52.5 days = 105/2 days

C and A can do the same task in = 42 days

Let altogether they can complete the task in x days

x (1/70 + 2/105 + 1/42) = 2

⇒ x [(3 + 4 + 5)/210] = 2

⇒ x (12/210) = 2

⇒ x = 2 × (210/12)

⇒ x = 35 days

A’s one day’s work = 1/35 – 2/105 = (3 – 2)/105 = 1/105

A alone can complete the whole task in = 105 days

B’s one day’s work = 1/35 – 1/42 = (6 – 5)/210 = 1/210

B alone can complete the whole task in = 210 days

D. v² = u² + 2as

Solutions

CONCEPT:

Equation of motion: The mathematical equations used to find the final velocity, displacements, time, etc of a moving object without considering force acting on it are called equations of motion.
These equations are only valid when the acceleration of the body is constant and they move on a straight line.

There are three equations of motion:

V = u + at

V2 = u2 + 2 a S

Where, V = final velocity, u = initial velocity, s = distance travelled by the body under motion, a = acceleration of body under motion, and t = time taken by the body under motion.

EXPLANATION:

From the above explanation, it is clear that the equation given in option 1 is not the equation of motion. So option 1 is correct.

D. Either statement I or II is sufficient

Solutions

Simple interest = Rs. 100

From the statement 1 rate of interest = 20%

From statement 2 time = 5 years

As we know,

SI = Prt/100

100 = (P × 20 × 5)/100

⇒ P = 100

Now, we can say both 1 and 2 statements are sufficient to give the answer.

96. Which of the following statements is correct?

A. Two or more resistors are said to be connected in series if different current flows through them

B. Two or more resistors are said to be connected in series if the same current flows through them.

C. Two or more resistors are said to be connected in parallel if the same current flows through them.

D. Two or more resistors are said to be connected in parallel if different current flows through them.

Solutions

In the series connection of the two or more than two resistors, then the current flows in all the resistors will always be the same.
In the series connection of the resistor, the equivalent resistance will be equal to the sum of all the resistors individually.
In the parallel combination, the potential difference always isthe same in all the combinations.
