Put these in order of which structures blood flows through in the heart:
Right atrium, Left Atrium, Vena cava, Lungs, Aorta, Right ventricle , left ventricle, Pulmonary vein, Pulmonary artery
Vena Cava -> Right Atrium -> Right Ventricle -> Pulmonary Arteries -> lungs -> Pulmonary Veins -> Left Atrium -> Left Ventricle -> Aorta
A bird’s nest is 38 cm from a converging lens. This lens has a focal length of 18 cm. Where will the image of the nest be located?
f=18cm do=38cm
1/f = 1/do + 1/di
1/di = 1/f - 1/do
1/di = 1/18 - 1/38
1/di = 0.02924
1/di = 0.02924-1 Therefore di= 34.2cm
