A string of length L = 2.6 m and mass m = 0.025 kg is fixed between two stationary points, and when the string is played a transverse wave of frequency f = 104 Hz is generated. The wave is vibrating in an unknown harmonic. Randomized Variables:
L = 2.6 m
m = 0.025 kg
f = 104 Hz
Part (a) What is the strings linear density, ρ, in kilograms per meter?
Part (b) If the wavelength is λ = 10.0 cm what is the tension in N?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
