10 times.
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')
Depends ... if the orchestra is playing pianissimo and the soloist fortisimo, then the soloist would be more intense.
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
Better think of the sound pressure, when you are listening. Sound pressure moves your ears and the diaphragm of the microphones. The sound intensity is very small. The level of 50 dB is equal to 0.0000001 W/m2 acoustic intensity. Scroll down to related links and look at "Conversion of sound units (levels)".
The ear drums feel the sound pressure difference of the factor 100; that is 20 log 100 = 40 dB. The microphone at a sound pressure level meter (SPL) can measure that.
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')

There are three syllables in the word "soloist" (so-lo-ist).
It varies depending on the size of the orchestra. The sound must be balanced.
The amount of intensity of a choir will vary depending on the number of people in the choir. For example if there are three people in a choir, they will be three times as strong as a single soloist. Fifty choir members will be fifty times as strong as a single soloist.
A ritornello is the form that typically begins a movement. Ritornello form focuses on a contrast between two musical ideas (the soloist and the orchestra for example). The idea presented in the ritornello will be revisited many times again in the song.
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
A decibel is a measure of sound intensity. Punches are normally measured for speed or force, I've never heard of anyone measuring a punch for its sound intensity.

Yes, but it's not easy to understand. There is a dependance of sound levels and corresponding factors: Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power). Scroll down to related links and look at "Sound level change and the loudness factor".
That depends on the sort of orchestra you want to record and what sound you indend to get. Are some or all musical instruments amplified or is it an unaplified symphony orchestra? How many persons are playing. Should it sound natural or artificial like all rock bands do? There are much more questions before there are some answers. For a stereo recording you need at least two microphones.
There are many ways a soloist can display his virtuosity to the fullest. Most often this happens during the cadenza of a concerto.
