The equation T^2=A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A

, in astronomical units, AU. If planet Y is twice the mean distance from the sun as planet X, by what factor is the orbital period increased?

Answer with explanation:

The Equation which is relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU.

 → T^2=A^3

For Planet , X

A_{1}=x AU\\\\(T_{1})^2=x^3

                                        --------------------------------------(1)

And, For Planet ,Y

A_{2}=2 x AU\\\\(T_{2})^2=(2 x)^3

                                       -----------------------------------------(2)

Dividing equation (1) by (2)

\frac{(T_{1})^2}{(T_{2})^2}=\frac{x^3}{(2x)^3}

[\frac{(T_{1})}{(T_{2})}]^2=\frac{x^3}{8 x^3}\\\\\frac{(T_{1})}{(T_{2})}=\sqrt{\frac{1}{8}}\\\\ T_{2}={2\sqrt{2}}{T_{1}}

→Orbital Period of Planet Y increases by, 2√2 times =2 ×1.414=2.828 times than planet X.

Special Right Trianglws
Masteriza [31]

Answer:

x = 2\sqrt7

y = 2\sqrt7

Step-by-step explanation:

Hello!

This is a right isosceles triangle (45°-45°-90°). You can solve for the missing angle by simply subtracting 45° and 90° from 180° (sum of angles in a triangle equals 180°)

Since the triangle is isosceles, x and y are congruent because they are the legs opposite to the congruent angles.

In a right isosceles triangle, the hypotenuse is always the measure of one leg multiplied by \sqrt2.

So, let's use leg y, y\sqrt2 = 2\sqrt{14}

Solve for y:

y\sqrt2 = 2\sqrt{14}\\\\y = $\frac{2\sqrt{14}}{\sqrt2}$\\\\y = 2\sqrt7

y = 2\sqrt7, which means that x is also 2\sqrt7
