I submitted a question form last week but I'm guessing it didn't go through along with an assignment. I'll have to figure out what assignment it was.
@& Nothing appears from the Question Form between 2/10 and 2/20.
It's a good idea to save your form confirmations. If I can verify that the form has malfunctioned then I can have our tech staff check it out.*@
Below is what you sent regarding the followup to bottle experiment 2a.
@& In the first trial, for example, you raised about 90 mL of water to a height of 17 cm.
90 mL of water, raised 17 cm, experiences a PE increase much less than 36 Joules. The volume of water raised was not .17 m * pi * .02 m^2, it was 90 mL.*@
&&&&
What I'm asking is I refigured the PE of the system using 89 ml and ended up with a PE of 148 J--
Redoing the PE of the 3:
=(.089 L)1000 kg/m^3)(9.8 m/s^2)(.17 m)=148 J
@& The units of your calculation would be L kg m^2 / ( m^3 seconds^2).
If your L was expressed as .001 m^3, then your units would be kg m^2 / s^2, or Joules. Your number would be .001 as great, or .148 Joules, which is reasonable.
148 Joules is more like what you would put into a hammer throw.*@
What am I doing wrong? I think I can figure out the rest if I can get past this.
Additionally in that question form, I asked about prioritizing the assignments...I know the labs are super important and I'm trying to study for the test, as you'll be getting sample questions later, but I've been spending a lot of time just filling in the answers to the worksheets we go over in class. We sort of addressed this in class last Wednesday. Do you just want us to put OK, in the slot for the questions we answered in class?
Just want to make sure I'm doing all that I'm supposed to. I don't like getting too far behind!
Thanks!

@& Check my response. Easy to fix, and a lesson about units. The space probe (or maybe the hammer) would have crashed into Mars for sure.*@
