Hon Chemistry 10-19-18 Chemical Names & Formulas

HON CHEMISTRY: Great start on writing and naming chemical formulas! What did you think? Do-able? Absolutely! Make sure to take time to practice, practice, practice, and learn it step by step. You’ll be as lost as ball in high weeds if you let yourself get behind!

Tons of memorization for this chapter – monatomic ions, polyatomic ions, and this is just the beginning! Start now!!

Physics 10-19-18 And Did the Hammock Crash?

PHYSICS: Great work today thinking through this one and also the “Wanda has a sign” problems! How you look at problems from the beginning can make a huge difference – huh?

A couple of things that work for me when doing equilibrium, etc., problems – first, draw them. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals everything right, and all the forces up equal all the forces down.

You’ve got all the ammo you need, now go forth and conquer!

Answers for the Equilibrants II worksheet are below:

  1. Fn = 3430 N upward against feet
  2. Fn1 = Fn2 = 1890 N upward on each foot
  3. F forward = 4.59 N
  4. T1 = T2 = 1760 N
  5. T1 = 1360 N and T2 = 680. N
