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.

What is the synodic period of mars?
The synodic period of Mars is approximately 780 days, which is the time it takes for Mars to return to the same position relative to Earth and the Sun as observed from Earth. This period is influenced by both Mars' orbital period and Earth's orbital period around the Sun. Mars takes about 687 Earth days to complete one orbit around the Sun, while Earth takes about 365 days, leading to the longer synodic period. As a result, Mars appears to undergo retrograde motion and other positional changes as both planets orbit the Sun.
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
Define the period of repolarization when only a strong stimulus will elicit an action potential?
The period of relative refractory period is the time after an action potential during which a strong stimulus is required to generate a new action potential. This is because the membrane potential is hyperpolarized, making it more difficult to reach the threshold for firing another action potential.
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
Saturn going through a period of apparent retrograde motion?
Saturn appears to go through retrograde motion when it orbits the Sun at a slower pace relative to the Earth's orbit. This phenomenon creates an illusion where from Earth, Saturn appears to be moving backward in its orbit. Retrograde motion occurs when planets are at specific points in their orbits relative to Earth.
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.
What is the movement of an object called?
The movement of an object is called motion. It involves a change in position relative to a reference point over a period of time. Motion can be described in terms of speed, direction, and acceleration.
What is the relationship between the sidereal and synodic periods in celestial mechanics?
The sidereal period is the time it takes for a celestial body to complete one orbit relative to the fixed stars, while the synodic period is the time it takes for a celestial body to return to the same position relative to the Sun as seen from Earth. The relationship between the two periods is influenced by the relative motion of the Earth and the celestial body, and can vary depending on their orbits and positions.
What is the motion in which Mars appeared to reverse its normal direction of motion in the sky?
The motion in which Mars appears to reverse its normal direction of motion in the sky is called retrograde motion. This phenomenon occurs when Earth, which moves faster in its orbit, overtakes Mars and creates the illusion that Mars is moving backwards in the sky for a brief period of time.
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.

What is the relationship between the relative refractory period and the absolute refractory period in terms of neuronal excitability?
The relative refractory period is the time when a neuron can respond to a stronger stimulus, while the absolute refractory period is when a neuron cannot respond at all. The relative refractory period follows the absolute refractory period and allows for increased neuronal excitability.
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
How to calculate the period of a simple harmonic motion?
by using the formula we will calculat time period of simple harmonic motion
Which of the following is true of a base period for an index number?
A base period for an index number serves as the reference point for comparison with other periods. It is typically assigned a value of 100 for simplicity in calculations. The base period allows for tracking changes in the index over time relative to a fixed point.
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.
