Question

a periapsis is its shortest distance its mean distance i, ne engh or he he apoapsils of a planet is ts greatest distance from the star, and the perlapoils is is İstance torn the sta, and The ofil of a planet around its ster is an epse with the star at one focus T simajor asis The apoapsis of a planet in 513 million miles the star is 226 million es from the center of the ortit whuat is the perisgsis? What i thoofepl is the mean distance? Wie an equation On OA O DX Oc 510 76 24 492 16

Answer 1

Given

a + c = 513 million milles

c = 22.6 million milles

a = 513 - 22.6 = 490.4

helion

Mean distance = 490.4million milles

​periapsis = b

a = c + b

b = a - c = 490.4 - 22.6 = 467.8

​periapsis = 467.8 million milles

Equation:

a2 b2

$c^2=a^2-b^2\\$

$b^2=a^2-c^2\\$

b2-490.42-22.62-239. 98 1.4

Equation:

240, 492.16 239,981.4

Answer : B
