In the lab, you will be creating shallow water waves with a "ripple" generator. When you attach a long horizontal rod to the generator it makes plane waves that behave much like waves on a string (see chapter 15). The speed of the waves in the ripple tank depends on the depth of the water layer. In the lab, you will measure the wavelength of the plane waves for different frequencies at the same depth of the water. When you double the frequency you expect the wavelength to
a. become has as large as before
b. stay the sama
c. become four times as large as before
d. become twice as large as before

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
