what kind of relationship, if any, exists between an orbit's semimajor axis length and
its period?
a direct
b inverse
cno relationship

Answer:

Orbit's semi-major axis length and  its period  is directly proportional.

Explanation:

Orbital period(T) is the time taken for an celestial object to make one complete revolution in the orbit around other object

According to  Kepler's laws  3rd of planetary motion  stating

The square of an orbital period T of a planet is “directly proportional” to the cube of the "semi-major axis"  of its orbit.

The orbital period  T is given by

Where

a is the semi-major axis of the orbit

µ = GM  which is the standard gravitational parameter

With G is the gravitational constant  and M is the mass of  body.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
