How did the articles of confederation compare to the constitution in regard to sovereignty?

natita [175]

States enjoyed greater autonomy under the Articles, whereas the Constitution granted some powers to the states.

<h3>What is articles of confederation?</h3>

The 13 founding states of the United States of America came to an agreement known as the Articles of Confederation and Perpetual Union, which functioned as the country's first system of governance.
On November 15, 1777, the Second Continental Congress approved it following lengthy discussion and forwarded it to the states for ratification.
In the Articles of Confederation, which served as the nation's first constitution, the confederacy of the former 13 colonies was referred to as "The United States of America."
The 13 articles that made up the Articles of Confederation granted authority to a federal government headed by Congress.
Following the United States' declaration of independence from Great Britain, the national government's functions were codified in the Articles of Confederation.
The Continental Congress approved the Articles of Confederation on November 15, 1777.
This text functioned as the first constitution of the United States.
It lasted from March 1, 1781, until the current Constitution took effect in 1789.

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m

Vanyuwa [196]

This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

<span>Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
$v=\frac{2\pi{r}}{T}$
</span> $=\frac{2\pi{r}}{1.88*365.25*86400}$ m/s, accounting for leap years
$=3.371*10^{-8}\pi{r}$ m/s

The centripetal force, Fc, generated is
$Fc=\frac{mv^2}{r}$
where m=mass of mars = 6.39*10^(24) kg
$=\frac{mv^2}{r}$
$=\frac{6.39*10^{24}v^2}{r}$
$=7.26168*10^9\pi^2r$

The gravitation pull from the sun, Fg, is given by
$Fg=\frac{GMm}{r^2}$
where G=grav. const., =6.67408*10^(-11) m^3<span> kg^(</span>-1)<span> s^(</span>-2)
M=mass of sun=1.989*10^(30) kg
$=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}$
$=\frac{8.4826*10^44}{r^2}$

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
$7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}$
Solving for the real root:
$r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}$
$=\frac{1.1681263*10^{35}}{\pi^2}$
=2.279*10^11 m

Which reproductive method is the only one available to mosses and ferns?

elena55 [62]

Answer:

Alternation of generation with both sexual and asexual

Explanation:

In mosses, the dominant plant is called a gametophyte while in ferm the dominant is sporophyte. Gametes are produced by the gametophyte and fertilization occurs forming an embryo. The embryo develops into a plant called the sporophyte.
