    Comparing Mass Reduction from Fusion of Nuclei

    1. Rank from greatest to least the reduction of mass per nucleon that accompanies the fusion of the following pairs of nuclei: a. Two hydrogen nuclei b. Two carbon nuclei c. Two aluminum nuclei d. Two iron nuclei 2. n/a 3. I know fusion is when two elements are combined and...

    Airplane Wings & Atmospheric Pressure

    I have a similar one that is related to this question (and I already have the answer) but I am confused to the concept of it and want to understand it.. "Consider an airplane with a total wing surface of 100^2 m. At a certain speed the difference in air pressure below and above the wings is...

    Airplane Wings & Atmospheric Pressure

    1. I got the correct answer but I am confused about the reasoning and want to understand the concept.. "Rank from most to least, the amount of lift on the following airplane wings: a. Area 1000 m^2 with atmospheric pressure difference of 2.0 N/m^2, b. Area 800 m^2 with atmospheric pressure...

    Why Do Lower Frequency Sounds Travel Easily Through Walls?

    Lower frequency = higher wavelength and higher frequency = lower wavelength; frequency and wavelength are inversely proportional I thought that that wavelength and intensity are related to each other...since lower frequency = higher wavelength which I thought meant greater intensity?

    Multiples of natural frequency?

    thx for your explanation. it clarifies things up a bit (I understand it 85% now) but just a little confused still. Your explanation was helpful though. Thanks for your response. :)

    Multiples of natural frequency?

    Multiples of natural frequency?? Hi all! I am a little confused. Why will an object not resonate with multiples of its natural frequency? I think due to the reason that through its multiples, it will not return (even if temporarily) to its natural state...am I mistaken?? Thanks in advance...

    Why Do Lower Frequency Sounds Travel Easily Through Walls?

    1. Apartment dwellers will testify that bass notes are more distinctly heard from music played in nearby apartments. Why do you suppose lower-frequency sounds travel through walls, floors, and ceilings more easily? 2. n/a 3. Lower frequency sounds travel through walls, floors, and...

    How do I express the frequency of the hour hand?

    I think 1/43,200 Hz? But I am just a little confused with the explanation.

    How do I express the frequency of the hour hand?

    I know that in a second it is 1/60 Hz. In a minute it is 1/3600 Hz. How do I express it in hour hand? I am a little confused.

    What does vigorously boiling water do?

    IF I am cooking something like potatoes, vigorously boiling water won't reduce my cooking time. What does it do then?

    What exactly is the difference between frequency and period?

    I am on the "sound" chapter in my Conceptual Physics class but I just wanted to know the best way to explain in layterm: what is the difference between frequency and period?

    Calculating Volume of a 100kg Mass in Freshwater

    1. Your friend of mass 100 kg can just barely float in freshwater. Calculate her approximate volume. n/a 3. I am confused in how I am supposed to solve this simple problem? Do I need to calculate the average density of fresh water * the 100 kg mass?

    Volume question (freshwater, saltwater, mercury)

    Sorry in posting so much; sense fresh water "submerges" the ball the least the order would be A, B, C as Mercury has the more density of the 3. Is this logic the correct reasoning?

    Volume question (freshwater, saltwater, mercury)

    What would be the final order of the results? I am just completely mixed up/confused what the question is exactly asking!
