Answer:

0.05 m from the top end

Explanation:

Data provided in the question:

Length of the violin string, λ₁ = 0.45 m

Frequency, f₁ = 392 Hz

New frequency of the violin note, f₂ = 440 Hz

Now,

The velocity of the wave in the string remains constant constant if tension remains constant.

Also,

velocity, v = fλ

thus,

f₁λ₁ = f₂λ₂

392 × 0.45 = 440 × λ₂

or

λ₂ = 0.40 m

thus,

The finger should be placed at (0.45 - 0.40 ) = 0.05 m from the top end

Is it possible for a human to multitask, or cognitively focus on two things at the same time?.
BigorU [14]

Studies show us that multitasking is not effective and makes us more prone to error. That's why multitasking for humans doesn't work.

<h3>Human multitasking</h3>

Multitasking is doing multiple work at once. Human brain, our brain, is incapable of performing multiple tasks at the same time. This happens even after extensive long training. It's because our brain isn't hardwired to do multiple tasks. Study on neurological science shows us that the human brain is not able to focus on two things at once. The other study shows that the human brain can only do two tasks at the same time, because it only has two hemispheres available for the tasks.
