    What is the speed of sound at this temperature?

    Homework Statement The speed of sound in air is proportional to the square root of the temperature in kelvin. A flute player begins playing with the temperature of air in the tube at 288 K. The speed of sound at this temperature is 340 m s–1. After a few minutes playing the air temperature in...

    How do we calculate percent error without a theoretical value?

    Yes! Thank you :) But can you tell me one more thing... what does the percent deviation tell me? As oppose to my percent error..? For instance I get my percent deviation to be 5%, and my percent error = 11%. What does this tell me? Thanks in advance~

    Calculating Average Acceleration

    Oh sorry, I guess you are right! Actually, the Time column shows "0" but the Acceleration column shows blank (so was the Velocity & Distance columns for the first row). I just assumed initial Acceleration will be 0 and include it on calculating the average acceleration, when in fact like you...

    Calculating Average Acceleration

    Hmm.. sorry, follow-up question... What if I'm calculating my average acceleration for gravity, do I need to include the "0" then? It's just that when I didn't include the "0" on my calculations, it was nearer the true value of "g" (9.81) But when I included zero in calculating my average, it...

    Calculating Average Acceleration

    Hi, this may seem like a silly question, but I'm gunna ask it anyway... I have the ff. data for acceleration: 0   9.152 8.43 9.07 7.731 10.423 When I calculate the average acceleration, would it be the sum divided by 6 or would it be the sum divided by 5? That is, should I include...

    How Do You Calculate Percent Disagreement?

    Whoops, I got the correct answer but I meant .541 - .715/.541 and my true value was actually .541 Anyway, I got it, thanks

    How Do You Calculate Percent Disagreement?

    Ok, I'm doing my Physics lab and I was told to give a "percent disagreement" if any.. I know it's a very simple question, but I want to make sure if I understood it right... So say I get an expected value to be .541 and when I calculated it, the answer is .715... so is the "percent...

    How many layers of atoms were deposited on the pennies during the experiment?

    i don't know where to post this, but we did a little experiment on pennies, and I'm having trouble with analyzing the calculations... basically the pennies turned into silver, the other gold.. after we heat it, etc inc. in mass of the pennies .0006 g density of the solid added to the...
