To solve this problem it is necessary to apply the concepts related to the Third Law of Kepler.

Kepler's third law tells us that the period is defined as

$T^2 = \frac{4\pi^2 d^3}{2GM}$

The given data are given with respect to known constants, for example the mass of the sun is

$m_s = 1.989*10^{30}$

The radius between the earth and the sun is given by

$r = 149.6*10^9m$

From the mentioned star it is known that this is 8.2 time mass of sun and it is 6.2 times the distance between earth and the sun

Therefore:

$m = 8.2*1.989*10^{30}$

$d = 6.2*149.6*10^6$

Substituting in Kepler's third law:

$T^2 = \frac{4\pi^2 d^3}{2}$

$T^2 = \frac{4\pi^2(6.2*149.6*10^9)^3}{2(6.674*10^{-11} )(8.2*1.989*10^30 )}$

$T=\sqrt{\frac{4\pi^2(6.2*149.6*10^9)^3}{2(6.674*10^{-11} )(8.2*1.989*10^30)}}$

$T = 120290789.7s$

$T = 120290789.7s(\frac{1year}{31536000s})$

$T \approx 3.8143 years$

Therefore the period of this star is 3.8years

ipn [44]

Answer:

4283.64 m away

Explanation:

$\beta$ = Bulk modulus

$\rho$ = Density

Speed of sound in a material is given by

$v=\sqrt{\frac{\beta}{\rho}}\\\Rightarrow v=\sqrt{\frac{2.1\times 10^9}{1030}}\\\Rightarrow v=1427.88\ m/s$

If the round trip takes 6 seconds then the one way trip wil take 3 seconds

Distance = Speed × Time

$Distance=1427.88\times 3=4283.64\ m$

So, the other submarine is 4283.64 m away
