The wavelength for C1 note is 10.40 m, for A6 note is 0.193 m and for B7 note 0.086 m.

Answer:

Explanation:

Since, wavelength, frequency and speed of sound waves are related to each other, we can determine a single parameter with the help of other two parameters. So in this case, the frequency of different notes are given along with their common speed. So as the frequency is inversely proportional to the wavelength then in this case, the wavelength of the notes will be maximum for C1 and minimum for 3951.1 Hz.

Wavelength = Speed / Frequency

Wavelength for C1 note = 340 / 32.7 =10.40 m

Similarly, the wavelength for A6 note  = 340/1760=0.193 m

And, the wavelength for B7 note = 340/3951.1 = 0.086 m

So, the wavelength for C1 note is 10.40 m, for A6 note is 0.193 m and for B7 note 0.086 m.

Explanation:

Center of gravity , Let center of rod is origin

= \frac{(0.400*0)+(0.800*\frac{50}{2}+10)+ (0.200 *(-(25+5)) }{0.400+0.800+0.200}

=15.71cm from the center of rod

As a system increases in volume, it absorbs 59.0 J of energy in the form of heat from the surroundings. The piston is working ag
Zepler [3.9K]

Answer:

The initial volume of the system is 2.7 L

Explanation:

The change in internal energy is given by;

ΔU = Q - W

where;

Q is the heat absorb from the surrounding

W is the work done by the system

Given;

ΔU  = -107.6 J

Q = 59 J

W = ?

W = Q- ΔU

W = 59J - (-107.6)

W = 166.6 J

Work done is given by;

W = PΔV

W = P(V₂ - V₁)

101.325 Joules = 1 L.atm

166.6 Joules  = ?

= 1.644 L.atm

1.644 L.atm = 0.543 atm(57.7L - V₁)

57.7L - V₁ = (1.644 L.atm) / (0.543 atm)

57.7L - V₁ = 3.0 L

V₁ = 57.7L - 3.0 L

V₁ = 2.7 L

Therefore, the initial volume of the system is 2.7 L
