If a star appears to move relative to other stars over a one-year period this motion is due to the star's?

That's called the star's "parallax", and is due to the changing position of the Earth - the Earth's orbit has a diameter of about 300 million km.

Define the period of repolarization when only a strong stimulus will elicit an action potential?
Relative refractory period
When do you use relative refractory period?
The relative refractory period is the time during which the generation of an action potential is impossible no matter the strength of the stimulus
What term do astronomers use for the time it takes for a planet to orbit the sun relative to the stars?
Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.
What is the result of the moons period of rotation?
how is the crater density used in the relative dating
Why is technetiums relative atomic mass usually found in brackets on the period table?
because it is an isotope???
What happens the apparent retrograde motion of the planet?
The planet's progress appears to slow down, or reverse its direction altogether so that it appears to move westward with respect to the stars over a period of many nights. It is important to note that this aberration of motion is an illusion - the planet in question has not changed its orbit in any way. Because of the relative motions among the observed planet and Earth, the observer on Earth sees an illusion, and from the observer's perspective, the planet appears to deviate from its normal orbit.
How far an object travels in a certain period of time is?
Relative or apparent motion.
What is it mean if your have ovairian cysts and you haven't had a period in oneyear started spotting 2 weeks ago and still spotting no full period yet had unprotected sex and worried could get pregnan?
You really should go see a doctor. You could be pregnant but not having your period yet you should check out.
Define the period of repolarization when only a strong stimulus will elicit an action potential?
Relative refractory period
How to calculate the period of a simple harmonic motion?
by using the formula we will calculat time period of simple harmonic motion
When do you use relative refractory period?
The relative refractory period is the time during which the generation of an action potential is impossible no matter the strength of the stimulus
What is the difference between noise and simple harmonic motion?
Simple harmonic motion is motion which is fully determined by its period, amplitude and phase. Noise is the name given to motion where the period is indeterminate. This may be because there is no periodicity or because the motion is a superposition of such a large number of simple harmonic motions of different periodicities that the resultant is almost aperiodic.Simple harmonic motion is motion which is fully determined by its period, amplitude and phase.

What causes apparent retrograde motion in planets?
As the Earth passes another planet in its orbit, the plant appears to move backward in the sky. This is an optical illusion. Earth takes 365 days to orbit the Sun, and all the outer planets take longer. Around the time of closest approach (opposition) to a planet, Mars for example, the Earth is moving more quickly both in terms of actual speed and of angular speed. At this time Mars appears to go backwards against the background of the fixed stars when we watch from the Earth. It's like, when you overtake another car on the motorway, it appears to be going backwards.
What is a motion that is constant over a period of time?
It is uniform motion in a straight line.
Saturn going through a period of apparent retrograde motion?
The Earth's velocity is faster than Saturn's. So we pass it once a year. When your car passes another, relative to you the other car is going backwards.
What is the differences between repetitive and periodic motion?
Repetitive motion means the action is repeated again after a brief period of time where as periodic motion means it repeats after a fixed period of time.
What is the period number in the periodic table?
The period number of an element is the row in which it appears.
