Most of the extrasolar planets discovered to date have been found by?
Observing a star carefully enough to notice that it is experiencing a gravitational tug caused by an unseen planet. Another possibility: The "transit " method was used very effectively in the Kepler space mission. I think that may be the main method to date.
Who is best suited to radial keratotomy?
Radial keratotomy is a surgical procedure used to correct nearsightedness (myopia). It is best suited for individuals with low to moderate levels of myopia who are not good candidates for other vision correction procedures like LASIK or PRK. It is important to consult with an ophthalmologist to determine if you are a suitable candidate for radial keratotomy.
When a star or galaxy moves quickly away it is called what?
We can measure fairly accurately the radial speed of a star or galaxy by measuring the Doppler shift of the emitted light from the star. Stars emit specific frequencies of light, and we can measure the frequencies to determine what elements are contained within the star. But since we know exactly what the frequencies are, we can measure the precise frequencies that we measure from the star. A star moving toward us will have its light "blue-shifted", or compressed a tiny bit in frequency. The amount of the compression tells us the radial velocity. A star whose light is red-shifted is moving away from us. Radial velocity is the part of the velocity that is directly toward or away from us; Doppler shifts don't tell us anything about a star's side-to-side motion. One of the astonishing discoveries of Edwin Hubble is that most galaxies are moving away from us, and the farther away they are, the faster they seem to be receding. Some nearby galaxies are moving closer, but the more distant the galaxy, the faster it is moving moving away. He determined this by the "red shift" of the light from distant galaxies.
Why do astronomers find it difficult to locate extrasolar planets with telephones?
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
What is average radial velocity of Mars?
The average radial velocity of Mars is 1.85° that is inclined to the ecliptic. While its inclination to the Sunâ??s equator 5.65° and its inclination to an invariable plane is 1.67°.
What is the relationship between radial force and angular velocity squared?
The relationship between radial force and angular velocity squared is described by the centripetal force equation, which states that the radial force required to keep an object moving in a circular path is equal to the mass of the object times the square of its angular velocity, multiplied by the radius of the circular path. This relationship shows that an increase in angular velocity will result in a corresponding increase in the radial force needed to maintain the object's circular motion.
Is the wobble method the same method as the radial velocity method?
yes it is
What factors should be considered when analyzing a velocity field that includes both radial and tangential components?
When analyzing a velocity field with both radial and tangential components, it is important to consider factors such as the direction and magnitude of the velocity vectors, the relationship between the radial and tangential components, and how they affect the overall flow of the system. Additionally, understanding the physical properties of the system and any external forces acting on it can help in interpreting the behavior of the velocity field.
What is the difference between radial acceleration and tangential acceleration in the context of circular motion?
Radial acceleration is the acceleration towards the center of a circle, while tangential acceleration is the acceleration along the edge of the circle. Radial acceleration changes the direction of velocity, while tangential acceleration changes the magnitude of velocity in circular motion.
How do you draw velocity and acceleration diagrams?
Velocity diagrams are drawn perpendicular to the link ....whereas acceleration diagrams are drawn by knowing the values 2 components radial or centripetal component and tangential component.......the radial component moves parallel to the link and perpendicular to the velocity diagram.....but the tangential component moves perpendicular to the link and parallel to the velocity diagram .
What is the difference between tangential and radial acceleration?
Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.
What is the most commonly used method for discovering exoplanets?
Radial Velocity (AKA Doppler Shift)
What is the radial velocity 55 Cancri e 0 1 2 what is it mean last digit birthday emans?
The radial velocity 55 Cancri e 0 1 2 is a binary star in the constellation of cancer. It is around 41 light years from the earth in 2010.
What characterizes constant velocity motion on a position time graph?
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
What is the relationship between radial and tangential acceleration in circular motion?
In circular motion, radial acceleration is perpendicular to the velocity and points towards the center of the circle, while tangential acceleration is parallel to the velocity and changes the speed of the object. The two accelerations are independent of each other and can act simultaneously in different directions.
