1. If the moon grew by a factor of 10,000 by how many orders of magnitude would it grow?

2. If a star increases its luminosity by 3.4 orders of magnitude, by what factor does its luminosity increase?

3.) A decibel scale is used to measure sound intensity. A change of 10 decibels means that the sound is 10 times more intense, and a change of 20 decibels means that the sound is 100 times more intense. If one sound has an intensity of 87 dB and a second sound is 1,000 times more intense, how many decibels is the second sound?5.) In science, prefix names are used to alter units of length, volume, and mass. The number line shows the orders of magnitude for specific prefixes. The prefix abbreviations are listed first with the prefix name listed below. (This is also where the conversions we've used come from!!) 10- 10 -$ 10- 7 1 n 10 - 6 10 -5 10 -4 10-3 10-2 10-1 m 101 102 nano 103 104 105 106 107 108 109 micro da M milli centi deci Based unit deca hecto kilo mega giga a.
