Highlight (in yellow) the correct word from each pair. 1. The amplitude of a wave can be measured from the (medium, crest) or the (trough,
wavelength) to the rest position.
2. Waves with greater amplitudes carry (more, less) energy than waves with smaller
amplitudes.
3. The wavelength of a transverse wave is often measured from (crest to crest, crest to
trough).
4. The number of waves that pass a point in one (second, minute) is the wave's (amplitude,
frequency).
5. Waves with longer wavelengths have a lower, higher) frequency and waves with shorter
wavelengths have a (lower, higher) frequency.

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m

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.

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.
