Why was it very difficult to get laws passed under the Articles of Confederation?

Nine of the 13 states must vote in favor of it.

Explanation:

The Articles of Confederation were the USA's first Constitution. When it was designed, it was done with the aim of having a weak national government and more powerful state governments.

There was no national executive or judicial branch and the legislative branch saw each of the 13 original states have 1 vote. To pass a law, 9 of these 13 states needed to vote in favor of it which made it really had to pass laws as the majority required was simply too large to be met from states that most times had differing interests.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
