Choose the best description of the radial velocity method of locating exoplanets. 1.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.
2.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.
3.The orbiting planet causes the star to wobble causing it to appear bluer or more red depending on which direction it moves.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
