SSA Chandigarh TGT Math Mock Test -4 - SSA Chandigarh MCQ

Explanation:
The communication mode that supports two-way traffic but in only one direction at a time is Half-duplex.
Here is a detailed explanation:
1. Simplex:
- Simplex communication mode allows data transmission in only one direction.
- It is a one-way communication mode where the sender can only send data, and the receiver can only receive data.
- There is no possibility of two-way communication in simplex mode.
2. Half-duplex:
- Half-duplex communication mode allows two-way traffic but in only one direction at a time.
- In this mode, both the sender and receiver can transmit and receive data, but not simultaneously.
- When one party is transmitting, the other party can only receive, and vice versa.
- It is like a walkie-talkie or a push-to-talk system where only one party can speak at a time.
3. Three-quarter's duplex:
- There is no such communication mode called "Three-quarter's duplex."
- It is an incorrect option.
4. Full duplex:
- Full-duplex communication mode allows simultaneous two-way traffic.
- In this mode, both the sender and receiver can transmit and receive data at the same time.
- It is like a regular telephone conversation where both parties can talk and listen simultaneously.
Therefore, the correct answer is Half-duplex (option B) as it supports two-way traffic but in only one direction at a time.

The correct answer is B: Select the image.
To delete an object, you must first select the object before performing any further actions. Here are the steps to delete an object:
1. Select the image:
- Click on the image to select it.
- This step is crucial as it indicates which object you want to delete.
2. Delete the image:
- Once the image is selected, you can proceed with deleting it.
- Press the Delete key on your keyboard or right-click on the image and choose the Delete option.
3. Confirm the deletion:
- In some cases, a confirmation dialog box may appear to confirm the deletion.
- Read the message carefully and click on the appropriate option to confirm the deletion.
4. Verify the deletion:
- After confirming the deletion, ensure that the image has been successfully removed from the location where it was placed.
Remember that these steps may vary depending on the software or application you are using to delete the object. However, the general principle of selecting the object before deleting it remains the same.

The process of converting analog signals into digital signals so that they can be processed by a receiving computer is referred to as:

Answer: D. Digitizing

Explanation:
To provide a detailed solution, let's break down the process of converting analog signals into digital signals and explain each step:
1. Analog Signals:
- Analog signals are continuous waveforms that represent real-world data such as sound, temperature, or light intensity.
- These signals have infinite possibilities and can take any value within a specific range.
2. Digital Signals:
- Digital signals are discrete and binary in nature, consisting of only two possible values: 0 and 1.
- These signals are used by computers and digital devices to represent and process information.
3. Process of Conversion:
- The process of converting analog signals into digital signals involves several steps:
a. Sampling:
- The analog signal is sampled at regular intervals to capture its amplitude at each point in time.
- The sampling rate determines the number of samples taken per second, also known as the sample rate.
b. Quantization:
- Each sampled value is quantized by assigning it a specific digital value from a predefined range.
- This process reduces the infinite possibilities of the analog signal to a finite number of digital values.
- The number of digital values available is determined by the bit depth or resolution.
c. Encoding:
- The quantized digital values are encoded into binary code, usually represented as a series of 0s and 1s.
- This encoding allows the digital signal to be transmitted or stored in a format that computers can process.
d. Transmission:
- The digital signal can now be transmitted over various communication channels such as cables, fiber optics, or wireless networks.
- The binary representation of the signal ensures accurate and reliable transmission.
e. Reception and Decoding:
- The receiving computer or device receives the digital signal and decodes it back into quantized values.
- The decoding process reverses the encoding and quantization steps, reconstructing the original analog signal.
f. Processing:
- Once the analog signal is converted back to digital form, the receiving computer can process it using various algorithms and techniques.
- Digital signal processing (DSP) techniques can be applied to manipulate, analyze, or extract information from the digital signal.
Conclusion:
- The entire process of converting analog signals into digital signals, including sampling, quantization, encoding, transmission, reception, decoding, and processing, is collectively known as digitizing.
- Therefore, the correct answer to the given question is D. Digitizing.

As we can say that ,
Tangible means available physically, concretely, elusive is something that eludes, i.e, is difficult to catch, touch or understand, palpable is a synonym to tangible.
Hence , Elusive is antonym word of Tangible . 

The original sentence "Her mother bought the house" is in the active voice.

Determinants of Individual differences in human beings relate to both heredity and environment interacting together. By heredity we mean the influence of factors inherent in the child himself from the time he is conceived. Environment also plays a key role in the individual's development.

Intelligence consists of learnable skills, and could be increased at any age. It is not permanent. 

Useful strategies for teaching students with mental retardation include the following:

• Teach one concept or activity component at a time
• Teach one step at a time to help support memorisation and sequencing
• Teach students in small groups, or one-on-one if possible
• Always provide multiple opportunities to practice skills in a number of different settings
• Use physical and verbal prompting to guide correct responses, and provide specific verbal praise to reinforce these responses

'Dyslexia' is a term known for reading disorder. The person having this disorder faces difficulty in learning to read or interpret words, letters, and other symbols, but it is not related to general intelligence. It will not have any impact on a person's general intelligence. It is a hereditary disorder that mostly runs in families. Hence, the correct answer is, 'Reading disorder.'

The response of a young child on the basis of the past situation is related to the 'Law of Analogy' of learning. 
The 'Law of Analogy' principle was developed by Edward Thorndike. According to him, an individual makes use of old experiences while learning a new situation. The way young child did he identified the similarities between the past situation and the present one.
Hence, the correct answer is, 'Law of Analogy' of learning.

Cognition is defined as the act of gaining knowledge through senses, thought and know-how.

The product of a non-zero rational number and an irrational number is always irrational.

Explanation:

• A rational number is a number that can be expressed as a fraction a/b ​, where a and b are integers and b≠0
• An irrational number cannot be expressed as a simple fraction and has a non-repeating, non-terminating decimal expansion.

When a non-zero rational number is multiplied by an irrational number, the product cannot be expressed as a simple fraction, and the non-terminating, non-repeating nature of the irrational number is preserved in the product, making the result irrational.

Answer: 1 (Always irrational)

 

Vector equation of a line that passes through the given point whose position vector is and parallel to a given vector is given by : 

 

Integrate it by parts taking  log (1+ x/2 )as first function

Taking different values of n we find that A and B are coprime

e.g. put n=1

we get A= 2(1)+13=15

B=1+7=8
∴ HCF = 1
 

put n=2

we get A= 2(2)+13=17

B=2+7=9
∴ HCF = 1

 f'(x) = [(logx).2−2x.1/x](logx)²
= 2(logx−1)/(logx)^2
∴f'(x)>0
⇔logx−1>0
⇔logx>1
⇔logx>loge
⇔x>e
∴f(x) is increasing in (e,∞)

1 + tan² x = sec² x
∫(π/2 to π/4)(sec² x)/(1 + tan² x)
=> ∫(π/2 to π/4)(sec² x)/(sec² x) dx
= ∫1(π/2 to π/4) dx
= [x](π/2 to π/4)
= π/2 - π/4  =  π/4 

The correct option is Option A.

If the angle is between 0 to 90 degrees then it will lies in the first quadrant.

The tanθ and sinθ have positive values, hence lies in first quadrant.
