Concept explainers
a.
To show: that the perihelion distance from a planet to the sun is
a.
Explanation of Solution
Given information:
The polar equation is
Proof: since, the polar equation for the elliptical orbit of the earth around the sun is
so the equation can be written as,
Now, from the equation, the perihelion distance from a planet to the sun is
b.
To find: the distances from the earth to the sun at perihelion and at aphelion.
b.
Answer to Problem 44E
The distance form the earth to the sun at perihelion and aphelion is
Explanation of Solution
Given information:
The equation is
Calculation: to find the approximate polar equation, substitute in the formula,
Thus, the distance form the earth to the sun at perihelion and aphelion is
