Halleys Comet. Rmin =8.9 x 10^10 m

Period of orbit = 2.4 x 10^9 sec
1)What is value of K for Halley's comet?
2)Whats the average radius of Halleys comet orbit?
3)What is value of the aphelion(Rmax) for halley's comet.(Rmin is perihelion. Recall Rave= [{Rmin +Rmax}/2]
4) what is Rmax/Rmin.

You can answer this by using Kepler's third law for planets (objects orbiting the sun), but I don't what you mean by the K value. The Law will tell you the semimajor axis for a given period. That is the same ars tha average radius.

You can answer this by using Kepler's third law for planets and comets (objects orbiting the sun), but I am quite what sure you mean by the K value. The Law will tell you the semimajor axis "a" for a given period T. The semimajor axis is the same as tha average radius.

T^2 = k a^3

k = 1 if a is in au and T is in years

To answer these questions, we need to understand the concept of the eccentricity of an orbit. The eccentricity (e) is a measure of the shape of an elliptical orbit. It ranges from 0 (for a perfect circle) to 1 (for a parabolic orbit).

1) To find the value of K (eccentricity), we can use the formula:
K = (Rmax - Rmin) / (Rmax + Rmin)

Given that Rmin = 8.9 x 10^10 m, we need to find the value of Rmax.

2) The average radius of Halley's comet orbit (Rave) can be calculated using the formula:
Rave = (Rmin + Rmax) / 2

We need the values of Rmin and Rmax to find Rave.

3) The aphelion (Rmax) is the maximum distance of Halley's comet from the Sun. It occurs at the furthest point in its orbit. Given that Rmin is the perihelion (minimum distance from the Sun), we can calculate Rmax as:
Rmax = 2 * Rave - Rmin

4) The ratio of Rmax to Rmin, Rmax/Rmin, can be obtained by substituting the values of Rmax and Rmin into the formula.

Let's calculate these values step by step.

1) To find the value of K (eccentricity):
K = (Rmax - Rmin) / (Rmax + Rmin)

2) To find the average radius of Halley's comet orbit (Rave):
Rave = (Rmin + Rmax) / 2

3) To find Rmax:
Rmax = 2 * Rave - Rmin

4) To find the ratio Rmax/Rmin.

Please provide the necessary values (if any) to proceed with the calculations.
