tree rings

Explanation:

A dendrochronologist interprets tree rings to ascertain the age of a particular tree.

Dendrochronology is a a scientific process that involves the dating of tree rings to determine the age of a particular tree.

  • It is sometimes called tree-ring dating.
  • This method of dating is mostly applicable to woody trees that have large years of growth.
  • New rings develops in order to accommodate new structural materials like the secondary xylem and phloem in them.
  • The nature of this secondary growth pattern can be used to systematically determine how old a particular tree is.

1) What gives an objedt gravity?
Reptile [31]

1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it

2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth

3) mass and how far away you are from the object

4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)

5) when distance increases, gravity decreases (again I do not remeber by how much)

Which one of the following sets of units is appropriate for a second-order rate constant?
Natalija [7]

Answer:

C. L mol-1 s-1.

Explanation:

Hello,

In this case, a rate law has the following general form:

r=kC^x_i

Whereas r accounts for the rate measured in M/s units, k is the rate constant whose units depends on the order of the reaction, C the concentration of the species in M units, contributing to the rate and x the order of the reaction.

In such a way, since in this case x equals two (second-order rate), the units of k turns out:

\frac{M}{s}=\frac{mol}{L*s}=k*(\frac{mol}{L}) ^2\\\frac{mol}{L*s}=k*\frac{mol^2}{L^2}\\\\k=\frac{L^2*mol}{mol^2*L*s} \\\\k=\frac{L}{mol*s}

Which matches with C. L mol-1 s-1.

Best regards.
