1.When a tsunami wave approaches the coast : - Does speed increase or decrease ? - Does height increase or decrease ? - Does wavelength increase or decrease ?
Explain why.
1). Tsunami waves are the seismic waves that are produced during an earthquake beneath the ocean. There are certain way to distinguish the tsunami wave from that of normal waves, and our easy answer would the height. But how it happen it is explained below,

Investigate why the amplitude of the tsunami (tidal wave due to the earthquake) increases as the tsunami approaches the shore. Investigate the relation between the speed of the wave propagating on the water surface and the depth of water Explain which curves can describe the perfectly constructive or destructive interference lines.
Inn to Question 1 (15 points): A small tsunami is moving at a speed of 36 kilometers per hour in the positive x-direction. The height, from the crest to the trough, of each wave is 4m (h = 4m). The distance between the first and third crest is 10m (d=10m). a) Find the wave equation assuming that at time zero the oscillation is at the crest as depicted in the diagram. Also, assuming that the vertical axis is the y-axis...
1. How is wave speed related to frequency and wavelength? 2. Does the frequency of a wave depend on the properties of the medium? 3. What happens to wavelength when speed is decreased? 4. What are two ways to decrease the speed of the wave (you can change the medium here, but how)?
1. What is a wave? How is wave speed related to frequency and wavelength? How is the period of oscillation related to the wave speed? 2. How does superposition produce interference between two waves? What are nodes and antinodes? What causes them in the standing wave pattern? 3. Stringed musical instruments, such as "fiddles" and banjos, used stretched strings. Explain (a) how tightening and loosening the strings tune them to their designated pitch or frequency; (b) why the strings of...
1 of 2) Calculate the speed, C, (in meters per second) of a tsunami with a wavelength of 180,000 meters (180 kilometers or112 miles) and period of 15 minutes traveling over the Pacific (which has an average depth of 4000 meters (4 kilometers or 2.5 miles). Round up your answer so that there is no decimal. Note that the answer is not 200 m/s as it is incorrect 2 of 2) Using the speed of the tsunami that you calculated...
If we increase the Tension (T) of a wave, the velocity of the wave increases (via v=sqrt(Tension/u)). Now using v=f*, what then happens to the frequency and wavelength? Does the frequency increase and the wavelength stay constant (or decrease)?
1. Does the resistance of the WHOLE circuit increase, decrease, or stay the same when additional light bulbs are added in series? 2. Does the voltage across each individual light bulb increase, decrease, or stay the same when additional light bulbs are added in series? 3. Does the resistance of the whole circuit increase, decrease, or stay the same when additional light bulbs are added in parallel? 4. Does the voltage across each individual light bulb increase, decrease, or stay...
During this process, does the puck's linear speed increase, decrease, or remain the same? A puck on a horizontal, frictionless surface is attached to a string that passes through a hole in the surface, as shown in the figure(Figure 1). As the puck rotates about the hole, the string is pulled downward, bringing the puck closer to the hole. O increases O decreases O remains the same Submit Request Answer Part B Complete previous part(s) Part During this process, does...
1. A wave train is observed approaching a coast that has straight parallel nearshore bottom contours that are oriented in a north-south direction. Where the water depth is 5 m the wave crests are observed to form an angle of 9° with the shoreline (waves from the southwest) and the wave period is measured to be 7.3 s. What is the incident wave direction in deep water? If the measured wave height at the 5 m depth is 2.2 m,...
1. Does the resistance of the whole circuit increase, decrease, or stay the same when additional light bulbs are added in parallel? 2. Does the voltage across each individual light bulb increase, decrease, or stay the same when additional light bulbs are added in parallel? 3. Are light bulbs brighter when they're connected in series or in parallel? 4. Consider a whole circuit. When the power supply is set to 12V, does the power supply provide more current to the...
