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.

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?

Hello, What is the difference between optically flat surface and atomically flat surface?

Hello, What are the important differences between CMOS and CCD? I am studying the digital cameras

Thank you very much

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?

Hello, is it possible to observe that with a diffusion ?

Hello guys, I need desperate help. I am googling an simple experiment that can observe interference patterns ? can someone help me out please?

nevermind i just found d=2r ;lol sorry

it just says compare the areas of wafers for the gven diameters .

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.

hello guys, i was looking over the book and 2 things made me confuse; 1st one is wht are the conditions for diode analysis. and why:? 2nd what is low level injection.. what do we need it for. thnx
