A string in a piano is tuned to emit sound with a fundamental frequency of "f" by adjusting the tension to be Ts. Which of the following modifications would give a fundamental frequency of 3f? Increase Ts to 3Ts. O Decrease Ts to Ts/9. O Decrease Ts to Ts/3. Owncrease Ts to 9Ts. It cannot be done by changing only the tension in the string.

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

1. A box (mass m = 20 kg) is
placed on a slope (LaTeX: \thetaθ = 40°), as shown in the diagram
below. The coefficients of friction between the box and the slope
are LaTeX: \muμs = 0.6 and LaTeX: \muμk = 0.4. The box is released
from rest on the slope.
Determine the acceleration of the box after it is released.

6. Two identical speakers are emitting sound of the same frequency. Speaker 1, located 5 m away, has a sound level of 76 dB. Speaker 2, located 10 m from you, has a sound level of 73 dB. Assuming spherically radiating sound waves, which of the two speakers is producing the sound at higher power? 7a. Express the fundamental frequency of a piano wire fixed at both ends in terms of its tension FT, length L, radius r, and the...

Question 9 1 pts Logan Roy is spending all his money income by buying mineral water and popcorn. At his current consumption level, the marginal utility of mineral water is 70 and the marginal utility of popcorn is 60. The price of a bottle of mineral water is $2.00 and the price of a box of popcorn is $1.50. The utility-maximizing rule suggests that Logan should: O Increase consumption of popcorn and increase consumption of mineral water Decrease consumption of...
