Answer:
Data provided in the question:
According to Kepler's Law, the square of the time "T" (measured in Earth years) required for a planet to orbit the sun varies directly with the cube of the mean distance "a" (measure in billions of miles) that the planet is from the sun, i.e.
where "k" is the constant.
a.
Time required by planet Mars to orbit the sun, Tm = 2
Mean distance of planet Mars from the sun, am = 0.142 billion miles.
On substituting the above values in the Kepler's Law equation, we get -
Therefore, we can write the equation for Kepler's Law as -
b.
Mean distance of planet Pluto from the sun, ap = 3.67 billion miles.
Time required by planet Pluto to orbit the sun, Tp = ?
We can use the equation of the Kepler's Law for calculating the time required by planet Pluto to orbit the sun as -
Thus, the time required by planet Pluto to orbit the sun is 262.792 Earth years.

please answer and show work for all parts of equation Kepler's Law, which states that the square of the time, T (measured in Earth years), required for a planet to orbit the Sun varies directly with the cube of the mean distance, d (measured in billions of kilometers), that the planet is from the Sun. 19 a. It takes Saturn approximately 30 Earth years to orbit the Sun with a mean distance of 1.4 billion kilometers. Use this information to...
1. Kepler's harmonic law of planetary motion (his 3rd law) states that the square of the orbital period is proportional to the cube of the characteristic distance of the planet from the sun. Test this by fitting a power law to the data below. Give your answer to 4 decimal places. Data file #period (days), distance (AU) # Data supporting Kepler's third law # distance is measured relative to the earth's mean distance, # which is about 9.26e7 miles and...
Pluto's distance P(t)(in billions of kilometers) from the sun as a function of time t (in years) can be modeled by a sinusoidal expression of the form a.sin(b.t)d At year t=0, Pluto is at its average distance from the sun, which is 6.9 billion kilometers. In 66 years, it is at its closest point to the sun, which is 4.4 billion kilometers away. Find P(t)
1 (10 pts). In 1601 the German astronomer Johannes Kepler became director of the Prague Observatory. Kepler had been helping Tycho Brache in collecting 13 years of observations on relative motion of the planet Mars. By 1609, Kepler had formulated his first two laws of planetary motion: i. Each planet moves on an ellipse with the sun at one focus. ii. For each planet, the line from the sun to the planet sweeps out equal areas is equal times. Kepler's...
Newton's version of Kepler's Law Force Example Use what we know about the earth's orbit to estimate the mass of the sun. For this problem we can use Newton's form of Kepler's law Solving for the sum of the masses we get to use this law we need all our values to be kilograms, meters, and seconds. a 1AU-149.6x10P m and p- 1 year (365.25 days/year)(24 hours/day)(3600 seconds/hour)-3.15x 10" sec. Placing these values in to our equation we get M+...
4. Use Kepler's Second Law and the fact that L-fxp to determine at which points in an elliptical orbit around the Sun a planet has maximum and minimum speeds. (Section 13.5 will help.) 5. At the end of example 13.10, there's an "Evaluate" blurb about how inside the surface of the Earth the force of gravity varies proportionally to the distance from the center, and it makes reference to the next chapter. which is about oscillation. Model the motion of...
11. Which of the following does the atmosphere of Mercury contain? a) Sulfuric acid b) Methane gas d) Mercury has no atmosphere of any kind c) Oxygen and nitrogen e) none of the above 12. Knowing that it takes about 8 minutes for the sun light to reach the earth, approximately how long does it take for the sun light to reach the planet Saturn? a) 8 minutes b) 40 minutes c) 3 hours and fifty minutes d) five hours...
Multivariable Calculus help with the magnitude of angular momentum: My questions is exercise 4 but I have attached exercise 1 and other notes that I was provided 4 Exercise 4. In any mechanics problem where the mass m is constant, the position vector F sweeps out equal areas in equal times the magnitude of the angular momentum ILI is conserved (Note: be sure to prove "if and only if") (Note: don't try to use Exercise 2 in the proof of...
