Which method of determining distance would be most appropriate for a ground-based observer trying to find accurate distances out to approximately 100 parsecs? (choose the lowest applicable rung on the cosmic distance ladder.)

Parallax                

Explanation:

            According to Mark Reid, an astronomer and an astrophysicist at Harvard Smithsonian Center, the Parallax method is the most accurate method to find distance in astronomy as it includes only geometry.

          Astronomers determine the distance of heavenly objects in the space by a method known as the trigonometric parallax or the stellar parallax.

            To measure a very large distances in space, for example the distance between a star or a  planet from Earth, the astronomers uses parallax principle. Here, parallax is defined as a semi-angle made by the inclination between the two sight-lines and the star, and this observation is taken when our Earth is on the opposite sides of  Sun.

Hence the answer is --- Parallax method.

the answer is the petition of right.

explanation:

offer to of right, real demand of attesting a benefit against the english crown, the most remarkable point of reference being the petition of right of 1628, which parliament sent to charles i fussing of a movement of oversteps of law. the term also implied the framework (invalidated in 1947) by which a subject could sue the crown.   taking a gander at the frameworks used by maria amidu to make a standard in 2015 commending the 1628 petition of right, which was sent to charles i by the english parliament. at uniquely based law the crown, or the sovereign in his official cutoff, couldn't be sued in the ruler's courts. since the ruler was, really, the superior ace of those courts, coordinating value in them between his subjects, he was not subject to their ward. therefore it transformed into a preparation, at whatever point a subject's certified or individual property had come into the responsibility for ruler or his specialists without legitimate perfect, for the subject to engage the master in chamber for its recovery.
