1.

9 trumpet players blast the same note with the same intensity for as long as possible. After a period of time, 3 trumpet players exhaust their breath and stop playing; what is the loudness of the remaining trumpet players is decreased by:

Hint: The sound intensity is decreased by a factor of 3 after 3 of the 9 trumpet players cease playing.

2.

A surgical laser imparts 5.0X10 ²J for 10.ns upon a 1.0mm ² surface of a tumor. what is the peak electric and magnetic fields.

given data; e ₀ = 8.85×10 ^-12C ²/N×m ², ? ₀ = 4 ?×10 ^-7T×m/A and c = 3.00×10 ⁸m/s

1. The fact that a trumpet and a saxaphone sound different when playing the same fundamental frequency is best explained by which concept listed below? a. The Doppler Effect b. Sound wave reflection c. Beats d. Timbre 2. A single-frequency air horn (f = 800 Hz) is sounded by a rider in a roller coaster moving toward you at 47 m/s as you stand next to the track. What frequency do you hear? Assume the speed of sound to be...

A trumpet creates a sound intensity level of 1.05 102 dB at a distance of 0.80 m. (a) What is the sound intensity of a trumpet at this distance? W/m2 (b) What is the sound intensity of five trumpets at this distance? W/m2 (c) Find the sound intensity of five trumpets at the location of the first row of an audience, 7.60 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions. W/m2 (d) Calculate the decibel level...

s] From a distance of ra = 8.000 m, a trumpet player plays an A note, f1 = 440.0 Hz, with a sound intensity level of β1 = 58.00 dB. A tuba plays in unison with the trumpet, but is slightly out of tune and has f2 = 437.00 Hz, and its sound intensity level is β2 = 63.50 dB. a) Calculate I1 and I2, the intensities of each instrument separately. b) When they play in unison, how many decibels...

1. There are two players. Each names an amount at the same time as the other. They can say $0 or say $10 or anything in between, even fractions of cents. If the amounts total $10 or less they get what they named. If they total more than $10 they get $0. What are the Nash equilbria? To solve this try some pairs of amounts. If they aren’t equilibria – if one player or both could do better by changing...
