    What is the x-value at which the body's velocity is 5.0 m/s?

    Does the force begin to act the object where x=0?

    High School Difference between static friction and kinetic friction

    Static friction cannot move the object from the rest. Friction makes objects slower or come to the rest or keep their rest position. Friction is against the motion. That's what I can add Doc Al's great answer.

    High School Why do astronauts feel weightless in space?

    I think u r confused about the meanings of weight and mass. weight=gravity.mass and it depends where u stand. Earth, mars, moon or smthn. But mass is same everywhere. As it is in space. Note: Astronaut has an accelaration? But feeling of jumping window (till touchin ground) contains...

    Undergrad Dividing Torque: Tangent and Centripetal Force Breakdown

    You mean torque or the direction of velocity in uniform circular motion? Maybe you can get some informaiton from this site: http://ray.crk.umn.edu/physics/1012/lessons/lesson8.pdf

    Mathematica Mathematically meaningful meter

    I agree with ZapperZ. Meter is just a measurement value that human beings use. That changes nothing in the laws. Maybe the choose of the measurement value can determine the easier way or the harder way for our calculations. I just wonder, what answer did u expect from the users when u were...

    Temperature Dependence on Pressure Change in Gases

    Check that link (it has the derivations of known equtions): http://66.102.9.104/search?q=cache:5MEJ5JLkdL4J:www.atmos.umd.edu/~russ/01_Intro.ppt+cp+-+cv+%3D+R&hl=tr&ct=clnk&cd=5&gl=tr

    Temperature Dependence on Pressure Change in Gases

    Your question is incomplete. Without both dU and dS, nothing can be found! But, there are some more useful equations here: http://www.grc.nasa.gov/WWW/K-12/airplane/compexp.html Check it! It will make it easier for you!

    Temperature Dependence on Pressure Change in Gases

    Here is the equation: "A gas with pressure P, temperature T, and chemical potential: dU=PdV+TdS+dN; where dV is the change in volume, dS is the change in entropy, and dN is the change in the number of particles. Note that this assumes that, prior to the changes indicated by the...

    High School Discovering Gravity: Galileo's Groundbreaking Findings

    He did his experiment in an airless place. Therefore; by the help of basic physics rules, he can solve the problem with just the time that is same for all matter in an airless place during freely fall. I hope u understand.

    High School Yes! Monochromatic Blue Light Can Reflect Red Light

    What I mean was this. I think we should gain some more information about the structure of monochromatic blue light. Maybe it can make the problem easier.

    High School Yes! Monochromatic Blue Light Can Reflect Red Light

    I don't think it's related with motion. Because, it is impossible to move a reflecter with the speed of light's. It's similar to speed of light waves. The answer is neither reasonable nor practical. I think it can be about the structure of the reflecter. Assume a reflecter that can observe all...

    Undergrad Could You Survive a Trip Through the Center of the Earth?

    As ZapperZ says 'This is identical to the harmonic mass-spring system.' I think it is the summary of the answer.
