A wave has a speed of 200 m/s and a wavelength of 4 m. What is period of the wave?

A high- speed lifting mechanism supports an 800- kg object with a steel cable that is 65.0 m long and 4.00 cm2 in cross- sectional area. Determine the elongation of the cable in mm. Young’s modulus of steel is 20×1010 Pa.

A sinusoidal wave moving along a string is shown twice in the figure, as crest A travels in the positive direction of an x axis by distance d = 6.20 cm in 4.10 ms. The tick marks along the axis are separated by 13.0 cm; height H = 6.00 mm. If the wave equation is of the form y(x, t) = ym sin(kx ± ωt ), what is the value of ω?

The vessels shown below all contain water to the same height. Rank them according to the pressure exerted by the water on the vessel bottoms, least to greatest.

A small ball of mass 0.64 kg is attached to one end of a 0.870-m-long massless rod, and the other end of the rod is hung from a pivot. When the resulting pendulum is 23° from the vertical, what is the magnitude of the torque about the pivot?

A block attached to a spring undergoes simple harmonic motion on a horizontal frictionless surface. Its total energy is 50 J. When the displacement is half the amplitude, the kinetic energy is:

A planet travels in an elliptical orbit about a star X as shown. The magnitude of the acceleration of the planet is:  

Calculate the escape speed from the earth for a 5000 kg  spacecraft. Given the mass of the earth is 5.97×1024 kg and radius of the earth is 6.37×106 m. 

Use the wave equation to find the speed of a wave given byy(x,t) = (2.16 mm) sin[(6.72 m-1)x – (5.19 s-1)t].

Spend 10-12 minutes on this question. Make a bullet point lost of five important specific things you know more about because of completing this class. It can be from any content covered this semester. For each one, write the statement of a specific area of new or improved knowledge, then write a few sentences explaining it.  For example, if this class were about Podcasting, for one of my five items, I could write:#1: I am better prepared to be able to create and publish a podcast. This is in part because I have new skills and understanding related to conducting interviews, plus I know more about the various types of content that I could include in a podcast. I also learned about publishing free on Buzzsprout, that connects my podcast to being available on Apple Podcasts.
