    Solving Anova Table? (stats problem)

    ok, here is an update. I get how to fill in the anova table for the ss and ms column. I think i understand how to calculate the f statistic by dividing the first ms number by the second ms number. What I still don't understand is how to get the probability. What numbers exactly do I put into my...

    Job to Pursue while Majoring in Physics?

    I am a non traditional student, 28 year high school dropout, who is starting on my third year of college majoring in astrophysics with the intention of earning a minimum of a masters either in physics or engineering. I am also going on my 7th year as a bicycle mechanic. I used to love my job but...

    Is Radiation the Primary Method of Heat Transfer in a Brick Oven?

    So...the pizza is heated from the heat that is stored in the bricks...via conduction? Similar to how the top of a regular stove is still hot 15 minutes after you turned the burner off. The stove top isn't radiating heat...as it is not in itself a heat source. But rather it is transferring...

    Is Radiation the Primary Method of Heat Transfer in a Brick Oven?

    Well, from what I understand... Convection is taking place to some degree, however since there is a chimney directly above then it would have to be very minimal. Now if the chimney was on the side of the oven, then convection would be taking a greater part in heating the pizza...though I...

    Is Radiation the Primary Method of Heat Transfer in a Brick Oven?

    The question is basically asking what method of heat transfer is MOSTLY responsible for heating a pizza inside of a brick oven. So from what I understand, the majority of the heat is coming from conduction-through the bricks themselves. Since the questions states that there is a chimney...

    Calculating Luminosity (Easy Atronomy Question)

    Capella is the same temperature as our sun, but about ten times the suns diamter; it must be about_____ times as luminous as our star. Could someone please tell me how to solve this type of problem?? I am aware of the formula R=sqrt(L)/Temp squared. But I'm not sure how to apply that...

    Need Help Understanding Angular Resolution

    When calculating angular resolution, is it correct that having a SMALLER number results in GREATER angular resolution? For example, is 26.25" better resolution than 2625"? Using the formula .25"(lambda in micrometre/diamter in meters), it would make sense to me that the larger the diameter...

    How much Trig is Needed to suceed in Calc?

    I am studying trig on my own in order to prepare myself for calculus. Just wondering how much I need to know. For example, would being familiar with the unit circle and inverse functions suffice, or should I thoroughly study every chapter of my trig book and know every concept to the best of my...

    Which Formulas Solve These Physics Problems?

    I've memorized all the formulas I need for my first intro to physics class...But I am still trying to get familiar with what formula to use for what problem. Here are two questions. If someone could tell me what formula i would use to solve them, that would be great! 1. At what rate does a...

    Introductory Bohrs Model Problem and I'm Lost

    AHHH! I get it. sort of. So from 2.34E14 hz I need to use this frequency to find the wavelength. Using the formula lambda= C/F, with speed of light as my constant, I get 1282E-6. This is REALLY close to my target of 1288! I just seem to be missing one last final step. I'm guessing I...

    Introductory Bohrs Model Problem and I'm Lost

    ok so i get how it comes to 2.34E14, I wasn't using parenthesis. Silly mistake! But I'm not sure what you are doing to get terra hz, or why, as I know my instructor never mentioned that term. Nor my book for that matter. Also, how is 1288 an acceptable answer? Thoughts??

    Introductory Bohrs Model Problem and I'm Lost

    Introductory Bohrs Model Problem...and I'm Lost! Ok, so I "think" what I am trying to find here is the frequency of the energy between two states of energy. I admit that part of my problem probably lies in the fact that I'm not even sure what it is I'm trying to find. My class seems to be just...

    Find the Reference Angle for 11pi/4

    I understand perfectly how to find the reference angle for a degree, such as 150 degress = reference angle of 30 degrees, because the 2nd quadrant goes from 90 to 180 degrees, so you simply subtract 150 from 180 to come up with 30. I get that: 11pi/4 = 495 degrees. 495 degrees will give you...
