    Equation for heat transfer rate

    Hi, I am trying to create an apparatus to measure the thermal conductivity of woody pellet based on peltier effect. the fundamental equation for thermal conductivity is Q"=kA(Δt/Δl), where k is thermal conductivity. A is the area of pellet, Δt is measured by using thermocouple and peltier...

    To find out the compression of the spring

    Hi PhanthomJay, Thanks for that, ,thats right, once the block contacted the spring, it should only act over x meter ,not the 4m, Thanks for that My understanding for the nonconservative force such as friction are involved is total initial and final energy=decrease in mechanical energy which...

    To find out the compression of the spring

    Hi BruceW, Thanks for your reply and sorry about not clearly explain the question yes, the equilibrium position is 4m down the slop from the block, the spring is unstretched(assume it is massless) it is not attached to the block from the start, it is at the bottom of the inclined plane, and...

    To find out the compression of the spring

    Homework Statement Hi Guys, I am trying to solve a classic problem involves conservation energy, spring, compression, I got my attempt and answer and I think my step was correct but the answer is different with the solution, can anyone please have look for me, any suggestions will be really...
