Answer:
The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m )
Curve amplitude : This is the maximum value of the radial velocity curve
Radial velocity shape ; The shape of Radial velocity curve is parabolic in nature
Orbital period : Orbital period is the time taken by the star to make one complete rotation in its orbit
Explanation:
The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m ) while Curve amplitude is the maximum value of the radial velocity curve also The shape of Radial velocity curve is parabolic in nature. and Orbital period is the time taken by the star to make one complete rotation in its orbit

Determine the percentage error
First, we need to determine the difference in the measurement




The percentage error is calculated as thus:




<em>approximated</em>
Answer:density
Explanation:
it’s how’s how dens the ball is
Well, you would have to divide 150 metres by 18 seconds.
150/18 = 8 1/3 m/s OR 8.333 m/s
Tyndall effect or Brownian movement and Particles of colloidal solution are the two properties that make solutions different from colloids.
