Choose the best description of the radial velocity method of locating exoplanets. A. This method is works well for detecting planets orbiting in close proximity to a star, so the planet can more readily observed passing in front of the star.
B. The orbiting planet causes the star to wobble causing it to appear bluer or more red depending on which direction it moves.
C. Planets are timed as they orbit distant stars. The size of the planet can be judged by time duration it takes to transit a star.​

What is created when solids, liquids, an gases mix with one another

He latent heat of vaporization for ethyl alcohol is 854 j/g. the amount of energy, rounded to the nearest whole number, needed to change 5.20 grams of ethyl alcohol from a liquid to a gas is

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
