We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
Most volcanoes are found at convergent or divergent plate boundaries, but intraplate volcanoes are found in the middle of a tectonic plate.
Answer:I think it’s self monitoring sorry if wrong
Explanation:
Answer:
The string is more likely to break when the circle is vertical
Explanation:
The string is more likely to break when the circle is vertical because tension in the string is the same throughout the circular motion and it is equal to mrw^2 when it is rotated in the horizontal plane while tension in the string is maximum and is given by mrw^2+mg when in the vertical plane.
