Identity element in set of rational number w.r.t multiplication is
-
0
-
1
-
-1
-
2
Correct Answer
A. 1Explanation
The identity element in the set of rational numbers with respect to multiplication is 1. This means that when any rational number is multiplied by 1, the result is the original number. For example, if we multiply any rational number, say 3/4, by 1, we get 3/4 as the result. Therefore, 1 is the correct answer as it satisfies the definition of an identity element in the set of rational numbers with respect to multiplication.Rate this question:

At which of the following places, motion of simple pendulum becomes slowest:
-
Murree
-
Karachi
-
K-2
-
Peshawar
Correct Answer
A. K-2Explanation
The motion of a simple pendulum becomes slowest at K-2. This is because K-2 is the highest peak in the Karakoram mountain range, located in Pakistan. At higher altitudes, the acceleration due to gravity decreases slightly, which affects the motion of the pendulum. As a result, the pendulum swings slower at K-2 compared to the other given places.Rate this question:

Equation of SHM, with amplitude 'a' is given by:
Correct Answer
A.Explanation
The equation of simple harmonic motion (SHM) with amplitude 'a' is given by y = a * sin(ωt), where y is the displacement of the object from its mean position, ω is the angular frequency, and t is the time. This equation represents the periodic motion of an object back and forth about its mean position along a straight line. The sine function ensures that the displacement varies sinusoidally, creating a smooth oscillation. The amplitude 'a' determines the maximum displacement of the object from its mean position.Rate this question:

If A and B are two Matrices then they can be added if
-
Have Same Order
-
Different Order
-
Can be Different Or Same
-
None
Correct Answer
A. Have Same OrderExplanation
Two matrices can be added if they have the same order, meaning they have the same number of rows and columns. This is because addition of matrices requires corresponding elements to be added together, which can only be done if the matrices have the same dimensions. If the matrices have different orders, they cannot be added. Similarly, if the question states that the matrices can have different or same orders, it implies that they can be added regardless of their order.Rate this question:

Sum of squares of conjugate complex number is?
-
Real Number
-
Imaginary Number
-
Complex Number
-
(b) and (c)
Correct Answer
A. Real NumberExplanation
The sum of squares of conjugate complex numbers is always a real number. This is because the conjugate of a complex number is obtained by changing the sign of its imaginary part. When we square a complex number and its conjugate, the imaginary parts cancel each other out, leaving only the real part. Therefore, the sum of squares of conjugate complex numbers will always result in a real number.Rate this question:

Correct Answer
A. Explanation
The current flowing through the circuit can be calculated using Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage is 120 volts and the resistance is 1000 ohms. Therefore, the current flowing through the circuit is 0.12 amperes or 120 A.Rate this question:

An electron is moving along the axis of a solenoid carrying a current which of the following is a correct statement about the electromagnetic force acting on the electron?
-
The force acts perpendicular to its motion
-
The force acts anti-parallel to its motion
-
The force acts in the direction of motion
-
No force acts
Correct Answer
A. The force acts perpendicular to its motionExplanation
When an electron moves along the axis of a solenoid carrying a current, the electromagnetic force acting on the electron is perpendicular to its motion. This is because the magnetic field created by the current in the solenoid interacts with the moving charge of the electron, resulting in a force that is perpendicular to both the motion of the electron and the magnetic field.Rate this question:

The sum of three numbers in AP is 15 and their product is 80. The largest number is:
-
2
-
5
-
8
-
11
Correct Answer
A. 8Explanation
Let the three numbers in the arithmetic progression be a-d, a, and a+d. From the given information, we can form two equations: (a-d) + a + (a+d) = 15 and (a-d)(a)(a+d) = 80. Simplifying the first equation, we get 3a = 15, which gives a = 5. Substituting this value into the second equation, we have (5-d)(5)(5+d) = 80. Solving this equation, we find d = 3. Therefore, the largest number is a+d = 5+3 = 8.Rate this question:

-
Recurring
-
Non-Terminating, non-recurring
-
Not defined
Correct Answer
A. RecurringExplanation
If a is a recurring decimal fraction, then 2a-3 will also be a recurring decimal fraction. This is because when we multiply a recurring decimal fraction by a constant (in this case 2) and subtract a constant (in this case 3), the resulting decimal will still have repeating patterns. Therefore, the answer is recurring.Rate this question:

The midpoints of a set of parallel chords of an ellipse are:
-
Co-linear
-
Non-Colinear
-
Can be Co-linear or Non-Colinear
-
None
Correct Answer
A. Co-linearExplanation
The midpoints of a set of parallel chords of an ellipse are co-linear. This means that if we take any two parallel chords of an ellipse and find their midpoints, these midpoints will lie on the same straight line. This property holds true for all parallel chords of an ellipse, regardless of their orientation or position on the ellipse. Therefore, the correct answer is that the midpoints of a set of parallel chords of an ellipse are co-linear.Rate this question:

When the output power equals to one-half of the input power, efficiency of the transformer becomes:
-
0 %
-
100 %
-
50 %
-
200 %
Correct Answer
A. 50 %Explanation
When the output power of a transformer is equal to one-half of the input power, it means that the transformer is operating at 50% efficiency. This indicates that only half of the input power is being successfully converted into useful output power, while the other half is being lost as heat or other forms of energy. Therefore, the efficiency of the transformer in this scenario is 50%.Rate this question:

Hydrocarbons which burn with smoky flame are called:
-
Aliphatic
-
Aromatic
-
Alicyclic
-
None of these
Correct Answer
A. AromaticExplanation
Aromatic hydrocarbons are compounds that contain a ring of carbon atoms with alternating double bonds. When they burn, they produce a smoky flame due to the incomplete combustion of carbon. Aliphatic hydrocarbons, on the other hand, burn with a clean flame. Alicyclic hydrocarbons are also aliphatic in nature and do not produce a smoky flame when burned. Therefore, the correct answer is Aromatic.Rate this question:

As temperature of the black body is raised the black body radiations become richer in :
-
Intermediate Wavelenths
-
Longer Wavelengths
-
Shorter Wavelengths
-
Low Frequencies
Correct Answer
A. Shorter WavelengthsExplanation
As the temperature of a black body is raised, the black body radiations become richer in shorter wavelengths. This is because the temperature increase causes the atoms and molecules in the black body to vibrate at higher frequencies, resulting in the emission of shorter wavelength radiation. This phenomenon is known as thermal radiation, and it follows Planck's law, which states that the intensity of radiation emitted by a black body is directly proportional to the frequency of the radiation. Therefore, as the temperature increases, the intensity of radiation at shorter wavelengths also increases.Rate this question:

A maintenance crew is working on a section of a three-lane highway only lane open to traffic. The result is much slower traffic flow. Do cars on a highway behave like:
-
The molecules of an incompressible fluid
-
The molecules of a compressed fluid
-
Both (a) and (b)
-
None of the above
Correct Answer
A. The molecules of a compressed fluidExplanation
Cars on a highway behave like the molecules of a compressed fluid. This is because when the maintenance crew is working on a section of the highway and only one lane is open to traffic, the cars are forced to compress and occupy a smaller space, similar to how molecules in a compressed fluid are closely packed together. This results in slower traffic flow as the cars have less space to move freely, just like molecules in a compressed fluid experience restricted movement.Rate this question:

![Pre Net 2015 Engineering By Taleem Tutor - Quiz]()
Correct Answer
A.Explanation
To double the total energy for a mass spring system oscillating in SHM, the amplitude must increase by a factor of 2. This is because the total energy of a mass spring system in SHM is directly proportional to the square of the amplitude.

Period of cos (3x + 7)=?
Correct Answer
A.Explanation
The period of the function cos(3x + 7) is 2π/3. This can be determined by finding the period of the standard cosine function, which is 2π, and then dividing it by the coefficient of x (3) in the argument of the cosine function. The constant term (7) does not affect the period of the function. Therefore, the period of cos(3x + 7) is 2π/3.Rate this question:

Correct Answer
A. 5Explanation
The sum of an arithmetic progression (A.P.) can be found using the formula Sn = (n/2)(2a + (n-1)d), where Sn is the sum of the first n terms, a is the first term, and d is the common difference. In this case, we are given that Sn = 600 and d = 5. Plugging in these values into the formula, we can solve for n. Once we find the value of n, we can substitute it back into the formula to find the value of the nth term. In this case, the value of n turns out to be 15, and substituting it back into the formula gives us the answer of 5.Rate this question:
