The snapshot graph to the right is of a wave pulse at t=2.0 s. The speed of the pulse is 1.0 m/s. A. Draw the snapshot graph for this pulse at t=0 s and t=3.5 s. Include labels on the axes. B. Draw a history graph for the point x=5.0 m for a time window of 0 s to 8.0 s.

As discussed in the chapter, many species of bats find flying insects by emitting pulses of ultrasound and listening for the reflections. This technique is called echolocation. Bats possess several adaptations that allow them to echolocate very effectively. Some bats have specially shaped noses that focus ultrasound echolocation pulses in the forward direction. Why is this useful?A. Increasing intensity reduces the time delay for a reflected pulse.B. The energy of the pulse is concentrated in a smaller area, so the intensity is larger; reflected pulses will have a larger intensity as well.C. Increasing intensity allows the bat to use a lower frequency and still have the same spatial resolution.

Mr. Daryl is giving an announcement, and he can be heard up to 30m. If you are standing 35m east and 25m south of Mr. Daryl, will you be able to hear his announcement? a. Yes, because I am only about 18.02 meters away from him. b. No, because I am about 43.01 meters away from him. C. Yes, because I am only about 25 meters away from him. d. No, because I am about 35 meters away from him.

This problem will require you to upload images of your work for credit. Label this "Problem B." You wake up and feel... off. You can't quite put your finger on it, but something feels wrong. You hear a ticking in the background and realize there is an old-school grandfather clock on the wall. The pendulum looks to be a meter long and is slowly ticking away. Timing it in your head, one swing takes about 2.5 seconds to complete. Wait. you were in Dr. Johnson's physics dass and know how these work! You had a lab on this! You rapidly calculate the local gravity at this location.. Are you even on EARTH?!? (Using your work, prove the assertion you make below). O NO! I have been abducted by aliens and they are trying to fool me by my one weakness: Victorian interior decorating! O Whew. Looks like I just fell asleep in a tour of the Tower of London. wait That's not good either!

G Part 1: Echo You are standing on a canyon edge and you give a shout. After 2.5s have passed, you hear your echo. The temperature at the canyon is -8.2°C. A.) Determine the speed of sound. B.) Determine how far away the cliff wall is that your voice bounced off of. G Part 2: Long cable A transverse wave pulse travels along a 30m long silver cable and returns 1.01s later. The cable has a radius of 0.7cm. A.) Determine the wave speed. B.) Determine the cable tension.

A mass suspended from a string is pulled down 15 inches from its rest position. The mass is released at time t = 0 and allowed to bounce above and below the rest position 12 times at a constant rate for 10 seconds. A. If, while at rest, the spring hangs 25 inches below where it is attached, determine an equation that models the height of the mass as a function of time, in t seconds. B. Determine the domain and range of this function.
