The earth revolves around the sun at speed of about 18.5 miles/sec (30 km/sec)

Answer from: maddietomlinson113

The Earth orbits the sun in an elliptical path, as do most large orbiting bodies. The force driving its travel is due to the gravitational pull of the sun. Gravity between two objects is related to the mass of the objects and the distance between them. Since the distance changes depending on where the Earth is at any given day it the elliptical path, the force of gravity, and thus the travel velocity, fluctuates.
On average, the Earth is 93 million miles (149,600,000 km) from the Sun, a distance is defined as one Astronomical Unit (AU), which takes one year (precisely 365.25 days) to complete an orbit. The extra 1/4 of a day each year accounts for why every four years we add an extra day in February (Leap Day). This is easier than trying to add one quarter of a day, or 6 hours, to each year.
The Earth revolves around the Sun at a speed of about 18.5 miles/sec, or 30 km/sec (0.5 km/min), on average despite where it is in its elliptical arc.

Answer from: Quest

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a 1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by 1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

The pharynx is the structure in the body that serves as a pathway of both air and food. how does the body make sure that food does not get into the lungs? the salivary glands secrete enzymes that pull food out of the air pathway. the small intestine pushes the air out of the digestive system. the pancreas breaks down food in the air pathway. the epiglottis closes the air pathway so that food will not enter it.
