4. Scientists are observing and recording data for two different planets, planet X and planet Y. Each planet orbits a different star. The planets have the same
mass. The scientists record the following data.
Star X-Planet X Star Y - Planet Y
Distance (millions of kilometers) 100
Gravitational Pull (Newtons)
390
260
100
Which of the following statements is most likely true?
a. The star close to planet Y is cooler.
b. The star close to planet Y has more mass.
c. The star close to planet X has more mass.
d. The sthr close to planet X is hotter.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

the answer is true. hope it .

ok whats the question if not i cannot you i need question and need a thing to answer
