    Scherrer Equation Question (XRD)

    i have 2th = 35.546 deg, d spacing 2.5236 A, fwhm 2 th - 0.148 deg, now can sombody put these values to get size of crystallite? i want to know the steps thanks

    What Are the Exact Scherrer Shape Factors for Different Crystallite Structures?

    I have value of 2 theta 35.546 deg, d spacing 2.5235 A, fwhm (2 th) 0.148 deg, can somone use it to get size of crystallite. after getting data analysed by a program expertplus i have got this, thankyou

    What distinguishes polar and nonpolar compounds?

    that depends upon the electronegativity. if electronegativity of one element is greater than the other atom, then charge develops it is said polar compounds. if electronegativity is same, it is non polar

    Experts please: DC CIRCUIT (PARALLEL-SERIES CIRCUIT) QUESTION

    your simplified diagram is wrong. use kirchhoffs law, there is no shortcut, as it is neither a wheatsotone bridge nor symmetrical circuit.

    Energy to charge capacitor and stored energy

    See, there is a basic difference between capacitor and cell. A cell supplies charge at constant potential, while the capacitor, transfers the charge at variable potentials, so in case of capacitor the formula is derived using integration. while transfering charge q at potential V a cell does...

    Estimate the buoyant force exerted on your body by the air

    just multilpy volume of body and density of air and accleration due to gravity. your weight will be more in vacuum.

    What is the fastest substance for sound to travel in?

    elasticity increases the speed of sound. so metals will give highest speed of sound in them. not only this the temperature, pressure, density, and molecular wt. also play role.

    How to Identify Phases and Miller Indices in XRD Data?

    Dear gokul i am fascinated by your helping nature. i have got a program named xpert plus which finds fwhm for the xray data with extension .raw. is the program feasible? can i have a program which could give the particle size directly. Nigarbage

    How to Identify Phases and Miller Indices in XRD Data?

    Dear gokul, we have got a program named xpert plus, which gives us fwhm value for the selected peak. is the program feasible. can we get a program which could directly find the particle size.
