Kepler qonuni - muammolar va yechimlar

1. The Earth’s masofa from the Sun is 149.6 x 10⁶ km and period of Earth’s revolution is 1 year. Calculate T² / r³

Ma'lum:

T = 1 year, r = 149.6 x 10⁶ km

Wanted :T² / r³ = … ?

qaror :

k = T² / r³ = 1² / (149.6 x 10⁶)³ = 1 / (3348071.9 x 10¹⁸) = 2.98 x 10^-25 yil²/ km³

2. Universal doimiy (G) = 6.67 x 10^-11 Nm²/kg² and Sun’s 1.99 x 10³⁰ kg.

3. The mean distance of Earth from the Sun is 149.6 x 10⁶ km and the mean distance of Mercury from the Sun is 57.9 x 10⁶ km. The period of Earth’s revolutions is 1 year, what is the period of Mercury’s revolution?

Ma'lum:

r of Earth = 149.6 x 10⁶ km

r of mercury = 57.9 x 10⁶ km

T of Earth = 1 year

Kerakli: T of mercury?
