Why did Newton conclude that some force had to pull the moon toward the earth
Why did Newton conclude that some force had to pull the moon toward the earth? how does the concept of a field explain action at a distance? name another kind of field also associated with action at a distance. how does the first postulate of special relativity imply the second ? if a plant has a moon, must that moon go through the same phases that earths moon displays? why do solar eclises happen only at new moon ? why not every new moon? why cant the moon eclipsed when its halfway between the nodes of its orbit? why would u not plot sound waves in the electomagnetic spectrum? if you had limited funds to build a large telescope, which type would u choose, a refractor?why? small telescop are often advertised as “200 power” or “magnifies 200times. how would u improve such advertisment? why do single dish radio telescope have poor resolving power relative to obtical telescopes? the moon has no atmosphere at all. what advanteges would u have to low tempratures? what might u detect with an x ray telescope that u could not detect with an infrared telescope? why do diffrent atoms have diffrent lines in their spectra? why does the amount of blackbody radiation emitted depend on the temprature of the object?
