A RipStik was ridden across a wet cloth towel soaked in water with food color. The RipStik was then swizzled across a large sheet of presentation paper. The swizzle wave can be seen in the image below.
The swizzle track consists of 5.5 wavelengths.
The swizzle track is 165 centimeters long.
The swizzle track took a duration of time of 1.79 seconds.
The distance across the wave (perpendicular to the direction of travel) from a crest to a trough for the swizzle track is 7 centimeters.
λ = _______________ Calculate the wavelength λ of the RipStik swizzle wave.
ѵripstick = _______________ Calculate the linear velocity ѵripstick of the RipStik.
a = _______________ Calculate the amplitude a of the RipStik swizzle wave.
τ = _______________ Calculate the period τ for the RipStik swizzle wave.
f = _______________ Calculate the RipStik swizzle wave frequency f.
ѵwave = _______________ Use the wavelength λ and frequency f to calculate the velocity ѵwave of the RipStik swizzle wave.
ѵ = _______________ During ten seconds a clapper claps 25 times. The echo flight distance is measured as being 140 meters. Based on this data, what is the speed of sound ѵ?
d = ________________ If you hear thunder twelve seconds after you see a lightning flash, how far away is the storm in kilometers d?
_______________ If you are standing in waist deep water on the reef and you see a fish in the water three meters away from you, is the fish actually shallower or deeper than the fish appears to be?
If you see lightning and hear thunder, what is the name of the cloud producing that lightning and thunder?
_______________ In an experiment to determine the density of a marble, a laboratory group obtained a result of 2.52 g/cm³. The theoretic value for the density of a marble is 2.57 g/cmcm³. What is their percentage difference between their result and the theoretic result?
