A star is formed from a Nebula (plural: nebulae). It is a cloud of dust and gas in Space. Some stars are formed at the same place where the previous star died. For example, a star explodes in supernova (such as supernova of Crab Nebula), the gasses and dust from the explosion remain behind that led to the birth of a new star.
Answer:
Explained
Explanation:
Along some shorelines, incoming waves cause the water to simply rise and fall and not form surfs because of the steepness of the shorelines. Long period waves wont form surfs at steep shores because of the breaking and unstability of waves. Wave breaks at the shallow waters. The breaking of the waves depends upon H/L ratio.
I associate "Tone" with sound frequencies. Tonic solfa being a music example which is basically, I think, using a certain musical key signature such as C major. In a major scale the sequence of "musical intervals" (ie frequency steps) is key note TONE TONE SEMITONE ... TONE TONE SEMITONE.octave higher than keynote.
So, I'd go for a here.

If two sets of data are correlated, this means that: one set causes the other to happen.
</h2>
Explanation:
Correlation indicates a relationship between two or more variables, but this relationship does not suggest cause and effect. When two sets of data are correlated, it means that as one variable changes, the other variable also changes.
The correlation can be measured by calculating a statistic called as correlation coefficient. The number from -1 to +1 indicates the strength and direction of the relationship between variables. The correlation coefficient is denoted by the letter r.
A magnet sitting next to a wire does not induce a current in the wire because <span> the magnet is very small and short compared to the coil radius. If you pretend it's two individual monopoles, they're only a few mm apart, so at several cm there's almost perfect cancellation of the fields.</span>
