A seated musician plays an A*5 note at 932 Hz. How much time At does it take for 721 air pressure maxima to pass a stationary listener? At = You would like to express the air pressure oscillations at a point in space in the given form. P (t) = Pmax Cos (Bt) If t is measured in seconds, what value should the quantity B have?

Preliminary Basic Calculations: The speed of sound is fast, but clearly not as great as the speed of light. There is a common observation that you can tell how far away a bolt of lighting is by counting the time in seconds between the flash (which arrives almost instantaneously) and the thunder. Each second of delay means the strike is 1/5 of a mile away. This implies that sound travels about 1/5 mile/sec or (5280/5) ft/sec≈ 1000 ft/sec. THE TIR (A) What is the approximate speed of sound in meters/sec? daca).sdut llod sdt mi is sd dguonit brs trigit (sbunito ngcourts fel bas fal asqo Page 1 of 10

Two metal bars are welded together to shape a more extended bar. The length of the primary bar is L₁ = = 0.97 ± 0.02 m And the length of the secondary bar is L2₂ 1.13 0.01 m. = Figure out the length of the bar (including uncertainty). Show your steps.

We have a very large sheet of extremely thin paper. Assume that the paper is in fact only 0.1mm(0.0039inches)thick.Imagine that thispaper will be foldedin half repeatedly, 50 times.Guess how thick the paper will be at the end!Quick metric system converter: 10mm=1cm (about 0.39 inches)100cm=1meter ( about 3.3 feet)1000m=1kilometer (about 0.62miles)

1. In this problem, you will work out the dimensions and units of quantities from equations. This is a very useful method for checking the physical validity of equations. (a) Consider a particle whose position x is given as a function of its speed v by the following equation v = Ce¯x, where b and C are positive constants. Find the units of C and b in the S.I system. Practice Quiz1 (b) Consider a particle velocity v is given as a function of time t by the following equation, v= Aw sin(at) where A, o are positive constants. Find the units of A and in S.I units. 2. A particle is moving in a straight line. The graph denotes the velocity of the particle as a function of time. (a) Draw a graph of the acceleration of the particle as a function of time. Your graph should include the magnitude and sign of the acceleration. (b) Draw a graph of the displacement of the particle as a function of time. The particle starts from x = 0. 10 8 (s/w) A AA 2.6 -8 -10- t (sec)

Hullo! Physics student here! I'm struggling to figure out how to go about answering this question ):  In one study of an adult bat, with a mass of 3.3 g and a wingspan of 111 mm, scientists found that this bat emitted a high-pitched sound that travelled 25.5 m in 78.7 ms. Calculate the speed of sound (in m/s) in this situation. Hint: Enter only the numerical part of your answer rounded to the nearest integer.
