In two to four paragraphs, explain what happened musically as Britten introduced the orchestral instruments:

Answers

-- Unless I miss my guess, the phrase "In two to four paragraphs,
explain ..." sounds like you want somebody to write a nice essay
for you, which you will then write your name at the top of and hand
it in as your own work. Are you sure you want to adopt this process
as a substitute for actually learning stuff ?

-- Sadly, you can probably forget about offering 5 points and getting
two to four paragraphs in return.

-- Another hunch of mine: You're referring to the "Young Person's
Guide to the Orchestra" ... a fugue and variations based on the
Rondeau from Henry Purcell's incidental music to Aphra Behm's
Abdelazar, composed by Benjamin Britten in 1946 for elementary
music education. The subject may not be too familiar to the people
who like to hang out here in the <Physics> category. You might
stand a better chance if you post the question again in <Arts> or
even <Social Studies>. I don't know of a way to 'move' a question
on Brainly, so you'll have to actually post it again ... and this time,
see if you can spare a few more points for an answer.

Answer:

Britten used a variety of instruments from different families and changed the traditional order. He started with the woodwinds, then strings, then brass, and percussion. He started with the highest pitched instruments in each of the families. This made the differences in the timbers of different sections of the orchestra more clear.

but he is right add more points next time you ask someone to do your work for you

Explanation:

The amount of heat neededto raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of
the substance?

Answers

Q = mcθ

Where Q = Amount of heat in J
   m = Mass of substance in kg
      θ = Temperature rise in °C or K
      C = Specific heat capacity in J/kgK

From given data:
Q = 33 kJ = 33 000 J, m= 2.0 kg, θ = 80 K, c = ?

33000 = 2 * c * 80
33000 = 160c
160c = 33000
   c = 33000/160 = 206.25

Therefore specific heat capacity is 206.25 J/kgK
