A student is carrying out an investigation in which a string of known length is plucked and then the student measures the resulting frequency of vibration in the string to determine the speed of the waves. If the student increases the tension in the string, how will it affect the frequency and speed of the waves in the string? (DOK 3) Question 15 options:

A. The speed will increase and the frequency will remain the same because the properties of the medium has changed but the wavelength will be the same.

B. Both the frequency and speed will increase because the properties of the medium have changed and the wavelength stays the same.

C. The frequency will increase but the speed will remain the same because the medium is the same but the wavelength is smaller.

D. Neither the frequency nor the speed will change because the medium is the same.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
