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

the answer of the structure of graphite is B
A case can move between state and federal jurisdictions when state laws are in conflict with federal laws, and certain claims are limited to federal court only explicitly stated in the Constitution or by Congress. A federal court can consider state law claim when such cases involve both state and federal laws. Claims based upon federal laws will permit a court to take over an entire case.
