SUMMARY

This discussion focuses on converting astronomical units (AU) to parsecs (pc) using a scientific calculator. The user is attempting to perform the calculation by dividing 1.496x1011 (AU) by 3.086x1016 (pc) but is struggling with the order of operations. The conversation emphasizes the importance of using the scientific notation feature (EE) on calculators to achieve accurate results in astronomical calculations.

PREREQUISITES
  • Understanding of astronomical units (AU) and parsecs (pc)
  • Familiarity with scientific notation and EE (10^EE) notation on calculators
  • Basic knowledge of order of operations in mathematics
  • Experience with scientific calculators
NEXT STEPS
  • Learn how to use scientific notation on calculators effectively
  • Research the conversion factors between astronomical units and parsecs
  • Practice order of operations with complex calculations
  • Explore astronomy calculators or software for unit conversions
USEFUL FOR

Astronomy students, educators, and anyone interested in performing accurate astronomical unit conversions using calculators.

I actually need help with using my calculator for astronomy equations. I am trying to do conversions from astronomical units to parsecs and vice versa, and the answers I am getting do not make sense. I believe I am simply performing my order of operations incorrectly, but after hours of trying, do not seem to be able to figure it out. Right now, I am trying to simplify to figure out what to do by dividing an astronomical unit by a parsec:
1.496x10^11/3.086x10^16. I think if I can simply figure out how to perform this, I should be able to figure out the problems with my assignments.

What numbers are you getting for a result? Are you using a scientific calculator with EE (10^EE) notation?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
