Answer from: datands

The correct answer is option C.

Explanation:

Acceleration is defined as rate of change of velocity with respect to time.

$Acceleration =\frac{Velocity}{Time}$

Acceleration of Xander = a_x

Velocity of Xander during the interval of 3.5 seconds = 4.5 m./s

$a_x=\frac{3.5 m/s}{4.5 s}=0.7777 m/s^2$

Acceleration of Finley= a_f

Velocity of Finley during the interval of 4.2 seconds = 3.6 m./s

$a_f=\frac{3.6 m/s}{4.2 s}=0.8571 m/s^2$

Acceleration of Max= a_m

Velocity of Max during the interval of 1.2 seconds = 7.3 m./s

$a_f=\frac{7.3 m/s}{1.2 s}=6.0833 m/s^2$

a_x

Xander → Finley → Max

The order of least to most acceleration will be the option C.

Answer from: Quest

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).

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
