As a wave moves through a medium, particles are displaced and (2 points)
a: return to their normal position after the wave passes.
b: remain in the new location after the wave passes.
c: are combibed with other particles forming the wave.
d: are moved along with the wave as it travels through the medium.

Which changes of state do the labels represent? a: b: c:

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot
