In the case that your ICA file doesn't open, it is highly likely that you do not have the correct software application installed on your PC to view or edit ICA file extensions. If your PC opens the ICA file, but it's the wrong application, you'll need to change your Windows registry file association settings.
He found the period of the planet's revolution around the Sun in years would be equal to the cube of its average distance from the Sun in astronomical units. Let us suppose we find an asteroid with a perihelion distance of 3 AU, and aphelion distance of 5 AU. Calculate its semimajor axis (average distance from the Sun) and use Kepler's Third Law to find its orbital period in years.
Best Answer: Your formula for the complete cycle period of a SIMPLE pendulum is: T = 2*Pi*sqrt(L/g) L is the length, g is the local gravitational field. sqrt() indicates the square root function. And Pi is the famous 3.14159 number, the ratio of circumference to diameter of any circle. If you quadruple the length of a simple pendulum, you will double the period of swing. In order to triple the period, you would need to increase the pendulum's length 9-fold. I use and emphasize the word simple, because the contrary is a physical pendulum.
