please help me with all the parts, there are 3 parts you can see if you piece the 2 screenshots together, please double and triple check bc the previous tutors got a wrong a few times.
You hear a seal produce an alarm call on the beach. Some of this alarm sound will also penetrate into the water to alert seals swimming underwater. Based upon your measurements of acoustic impedance, you calculate that the Reflection Coefficient R=0.5. Please answer both parts of this question and show your work. 1. How much of the sound energy will reflect back from the water into the air? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%) 2. How much of the sound energy will penetrate into the water? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%)
MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving toward Earth at a speed of 856.500 km/s. It emits mostly radio waves with a wavelength (at the source) of 132.500 cm. What is the observed wavelength of this radiation on Earth? (Assume the Earth is stationary. Consider the speed of light c = 3.00000 × 108 m/s. Give your answer to at least six significant figures.) 4.0 133 What relationship describes the frequency of a wave for an observer that is moving relative to the source? What is the relationship between frequency and wavelength? cm

PHET Simulation - Wave on a String Submit Previous Answers v Correct The effect of damping is akin to the absorbance or partial reflection of light, whore the amplitude of in phase photons becomes reduced. Part B Reset the PHET simulation (using the button in the lower tight) and set it up in the following manner select Oscillate, select No End, and use the parameters in parentheses by sliding the bars for Amplitude (1.00 cm). Frequency (2.00 Hz). Damping (none), and Tension (highest) Using the available Rulers, calculate the frequency of a photon that corresponds to the wavelength of the resulting wave. Assume the length with umits (cm) of the ruler represents the real photon wavelength and that the spced of light is 3.00 x 10° m/s.

Each of the diagrams below represents a snapshot of two springs at an instant after a pulse has reached the boundary between them. The linear mass density, µ, is greater for the tightly coiled spring than for the other spring. Each diagram may contain flaws that would not be observed with real springs. For each diagram: a. Determine whether there is a flaw. If there is a flaw, describe it (a single flaw is sufficient) and continue to the next diagram. If there are no flaws, answer parts b and c. b. Make a sketch that shows the shape, width, and direction of motion of the incident pulse. c. Determine which pulse is the reflected pulse and which is the transmitted pulse.
