oblicz długość wahadła matematycznego ktorego okres wynosi 1s przyjmij g=10N Kg
POMOCY !
T = 2 pi * p( l/g)
zatem
T^2 = 4 pi^2 *( l/g)
l/g = T^2 / [ 4 pi^2]
l = [ g*T^2]/ [ 4 pi^2]
T = 1 s
g = 10 N/kg
l = [ 10 N/ kg * 1 s^2]/[ 4 pi^2] = ( 10/4 pi^2) m = około 0,25 m
===========================================================
p( l/g) - pierwiastek kwadratowy z l/g
