Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed.

An exoplanetary system has two known planets. Planet X orbits in 290 days and Planet Y orbits in 145 days. Which planet is close

satela [25.4K]

Answer:

Planet Y

Rx = 1.587 Ry

Explanation:

Tx = 290 days

Ty = 145 days

Let the semi major axis of planet X is Rx and of plant Y is Ry.

According to the Kepler's third law of planetary motion

$\frac{T_{x}^{2}}{T_{y}^{2}}=\frac{R_{x}^{3}}{R_{y}^{3}}$

$\frac{290^{2}}{145^{2}}=\frac{R_{x}^{3}}{R_{y}^{3}}$

$4=\frac{R_{x}^{3}}{R_{y}^{3}}$

$1.587=\frac{R_{x}}{R_{y}}$

Rx = 1.587 Ry

So, planet Y is closest to star.
