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.
The period of oscillation of a simple pendulum may be found by the formula. As the first formula shows, the stronger the gravitational pull (the more massive a planet), the greater the value of g, and therefore, the shorter the period of oscillations of a pendulum swinging on that planet.
