A“new moon” coincides with the highest of the two spring tides. which position is the new moon?
a)
b)
c)
d)

A)

Explanation:

In astronomy, the new moon corresponds to the lunar phase during which the moon is between the earth and the sun. Therefore, we can say that in the image shown in the question above, the new moon is being represented by the letter A.

Therefore, it is very difficult to observe the New Moon because it is very close to the Sun. Since its visible side is not illuminated by the Sun during the day, it becomes invisible at night. The bright part we will see will grow from day to day.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
