3 AnswersMathematics1 decade agoHeisenberg uncertainty principle?
A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of = 0.200 (where a femtogram, , is ) and is swimming at a velocity of = 2.00 , with an uncertainty in the velocity of 9.00 . E. coli bacterial cells are around 1 ( ) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just learned about the Heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. She claims that the uncertainty of the bacterium's position is greater than the microscope's viewing field, and the bacterium is thus impossible to locate.

Chemistry1 decade agocan some one please explain this Turing code (i need to confer it to visual basic code)?
here is the code
function gcd (a, b : int) : int
% finds the greatest common divisor
if b = 0 then
result a
end if
result gcd (b, a mod b)
end gcd
function fractorial (a : int) : int
% uses recursion to multiply each new factor
% and dividing the greatest common divisor at each step
var temp : int
if a < 2 then
result a
end if
temp := fractorial (a - 1)
result a div gcd (temp, a) * temp
end fractorial
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
var f, x : int
open : f, "DATA11.txt", get
for i : 1 .. 5
get : f, x
put "fractorial(", x, ") = ", fractorial (x)
end for
and ya like i said i need to conver it to visual basic code if u know that language as well can u plaese convert it if not then just explain it.
