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.

Malaka’s mother tells her, “You have to be better than us.” Using developmental theory, explain how her parents’ aspirations and expectations shaped Malaka’s own developmental trajectory throughout her life. In your analysis, discuss how Malaka navigated, accepted, or redefined her parents’ vision for her. What does this reveal about the role of family systems and intergenerational dynamics in shaping psychological development? Support your answer with specific examples from Malaka’s story or concepts from our course. 100-150 words

What is the smallest radius of an unbanked (flat) track around which a bicyclist can travel if her speed is 32.9 km/h and the coefficient of static friction between tires and track is 0.382?

A puck of mass m = 1.60 kg slides in a circle of radius r = 18.0 cm on a frictionless table while attached to a hanging cylinder of mass M = 1.0 kg by a cord through a hole in the table. What speed keeps the cylinder at rest?
