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
Answer:
The war fostered influenza in the crowded conditions of military camps in the United States and in the trenches of the Western Front in Europe. The virus traveled with military personnel from camp to camp and across the Atlantic, and at the height of the American military involvement in the war, September-November 1918, influenza and pneumonia sickened 20%-40% of U.S. Army and Navy personnel. These high morbidity rates interfered with induction and training schedules in the United States and rendered hundreds of thousands of military personnel non-effective.

Answer:
Short term memory - Recency effect - last items in a list
Long term memory - Primacy effect - first items in a list
Explanation:
Recency effect is the one that is related with the short term memory that is why people normally remember the last items in a list easily. On the other hand, the primacy effect is responsible of the long term memory due to the huge effort that people put when they start the exercise knowing that it would be necessary to repeat the items later on.
