    Why does the rate of radioactive decay follow a decaying exponential function?

    Hello, I am curious. Eventhough, the half-time of an element is always the same. Why not we can't find quarter of elements vanish time, because; half life is directly proportional, 10gr 10 min -> 5gr 20min. if 10 gr vanishes in 10 min, 2.5gr vanishes in 2.5 min for 20gr radioactive material.

    Calculate Volume Flow Rate: Pressure & Speed

    Hi there, I have a lab project. Part of the project is to calculate the volume flow rate, I have 2 tubes,radius' are known , density of the fluid is known and pressure is known. How can i relate the pressure to speed?

    Why not indirect band gap for led

    Hey I was studying for my test, in my notes it says si cannot be used for led, because it has indirect band gap.Why indrect band gap is not useful for led?

    Area of Wafer: Pi*r^2 Explained

    Hello guys, I have an upcoming test. When I was doing a question about finding the area of the wafer. it is circular. In the solution manual it says pi*r^2 / 4 . I do not understand where 1/4 comes from. Since it is circular , I assumed the pi*r^2 would be fine.
