Step 4: Distance between A and B

Since they are on opposite sides of the tree:

✅ Final Answer: 

The Major Dhyan Chand Khel Ratna Award 2023 winner Chirag Chandrashekhar Shetty belongs to the sport of:

✅ Badminton

Explanation:

Chirag Shetty is a well-known Indian badminton player, famous for his success in men’s doubles, especially with partner Satwiksairaj Rankireddy.

Correct answer: Badminton

The value of 29² – 24² can be calculated using the difference of squares formula: (29 + 24)(29 – 24) = 53 × 5 = 265. Then, we have 25y² = 265, which gives y² = 10.6, so y = √10.6 ≈ 3.

The inductive reactance X_L is directly proportional to the frequency f, hence the graph should be a straight line passing through the origin.

A half-wave rectifier converts an AC input into a DC output, and the output voltage is typically the average value of the rectified waveform.

To simplify the given boolean expression X = A̅B + (A + B̅)C, apply distribution: X = A̅B + AC + B̅C. Thus, the simplified form is X = A̅B + C.

The S–R latch is an example of a:

✅ One-bit memory element

Explanation (exam-oriented):

• An S–R latch can store one bit of information (0 or 1)

• It is a basic sequential circuit with memory

• It does not require a clock (so it is not synchronous)

Why other options are incorrect:

• Combinational circuit → has no memory

• Synchronous sequential circuit → requires a clock

• One-clock delay element → refers to clocked flip-flops

Correct answer: One-bit memory element

Concept:

Ampere's law:

It states that the magnetic field created by an electric current is proportional to the size of that electric current with a constant of proportionality equal to the permeability of free space.

If a sinusoidal voltage is applied only to the vertical (Y) deflection plates of a CRO, then the spot moves up and down with time, while there is no horizontal deflection.

So, the trace formed on the screen is a: ✅ Vertical line

Why:

• Vertical plates → control vertical movement

• No voltage on horizontal plates → no left–right movement

• Continuous up–down motion → vertical line

Correct answer: Vertical line
