I think the second option is the best (by making the ramps height and length equal) because the first option will require more pushing, the third option will only make the ramp lighter which could cause it to not stay in place, the last option would make it harder to push the boxes up because the rubber will make it harder to slide the boxes up. I hope this helps:)

raketka [301]

Answer:

1)El ciclo del agua no se inicia en un lugar específico, pero para esta explicación asumimos que comienza en los océanos. ... Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.

2)El sol, que dirige el ciclo del agua, calienta el agua de los océanos, la cual se evapora hacia el aire como vapor de agua. Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.

Vessels draining the myocardium of the heart, open primarily ,into which chamber?

Kitty [74]

Answer:

The vessels draining Myocardium of the heart join to form Coronary Sinus that ultimately opens into THE RIGHT ATRIUM.

Explanation:

CORONARY CIRCULATION:

The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.

Coronary Arteries supply oxygen rich blood to the myocardium and Coronary Veins remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.
