spectrometer is a device that gives the spectrum of all intensities of a one wavelength at one time. it consists of the entrance & exit slits, dispersing element (like grating) &mirror. it detects the light and measure the intensities with a photomultiplier tube or other detectors and data acquisition system.
spectrograph also gives the spectrum of all intensities of a wavelength at one time.it consists of the entrance & exit slits, dispersing element (like grating) &mirror but it does not have any detector and does not record the spectrum.
D. Alignment of the Universe does not contribute to the changing of seasons. The changing of seasons is primarily influenced by the tilt of the Earth's axis as it orbits the Sun (B), along with the varying distance between the Earth and the Sun (C) throughout the year. The distance between the Earth and the Moon (A) mainly affects tides on Earth.

The gravitational force between two objects depends on their masses and the distance beween them. f = G m1 m2 / d2 where m1 and m2 are the masses, d is the distance between them and G is the universal gravitational constant.
The Gemological Institute of America (G.I.A.) grades color alphabetically from D (totally colorless) to Z (yellow).For a diamond to be considered “colorless,†the G.I.A. requires that it be a D, E, or F. However, the D-Z scale is continuous, so the difference between an F and G is very small. The average color for engagement diamonds in the retails industry is G to H.
When the moon is at positions a, c, or f (new moon, first quarter, third quarter), neap tides will occur. Neap tides have the least difference between high and low tide levels. When the moon is at position d (full moon), spring tides will occur, which have the greatest difference between high and low tide levels.
d
the differences between intonation and stress is the difference . ! :D :D hahahahahaa
generators which convert mechanical energy to electrical energy and motors which convert electrical energy to mechanical energy
The book is better :d
8===D~ i think that is the answer -ricardo interiano .---.
They used sticks we use guns ftw >:D!
They used sticks we use guns ftw >:D!
im sorry , i dont know the answer :D
the similartes between the drawing is the cow jumped over the moon and went home to his momma :) :) :D :D :P :P
the differences between adolf Hitler and Franklin d. roosevelt is that the were in different countries, one was a dictator and another was a preseident similarities are that they both ruled around that time, and they both wanted change, and also was on multimedia and news
i Dont know thats why im asking ! D:
Well for one thing, the time zones are different, and obviously, the names. :D
