This is another way you could also put it:

First Law of Thermodynamics Energy can be changed from one form to another, but it cannot be created or destroyed. The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy. In the process of energy transfer, some energy will dissipate as heat.

Answer:

Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy constantly increases in a closed system.

A pair of in-phase stereo speakers is placed side by side, 0.764 m apart. You stand directly in front of one of the speakers, 2.
Goryan [66]

Answer:

f = 2858.33 Hz

Explanation:

given,

distance between speaker (A) and the person = 2.34 m

Distance between speaker (B) and the person is AB =

            =\sqrt{(0.764)^2 + (2.34)^2}

            = 2.46 m

path difference d = BP - AP

                             = 2.46  - 2.34 m

                             = 0.12 m

now,    λ = 0.12

speed of sound =  343 m/s

    f= \dfrac{c}{\lambda}

    f= \dfrac{343}{0.12}

              f = 2858.33 Hz

the lowest frequency that will produce constructive interference is equal to

f = 2858.33 Hz

The error in the measurement of the radius of a sphere is 2%. What will be the error in the calculation of its volume?
BlackZzzverrR [31]

To solve this problem we will apply the geometric concepts of the Volume based on the consideration made of the radius measurement. The Volume must be written in differential terms of the radius and from the formula of the margin of error the respective response will be obtained.

The error in radius of sphere is not exceeding 2%

\frac{dr}{r} = \pm 0.02

The objective is to find the percentage error in the volume.

The volume can be defined as

V = \frac{4}{3} \pi r^3

Differentiate with respect the radius we have,

\frac{dV}{dr} = 4\pi r^2

dV = 4\pi r^2 \times dr

dV = 4\pi r^2 (\pm 0.02r)

dV = \pm 4\times 0.02 \times \pi r^3

The percentage change in the volume is as follows

\% change = \frac{dV}{V} \times 100

\% change = \frac{\pm 4 \times 0.02 \times \pi r^3 \times 3}{4\pi r^3}\times 100

\% change = \pm 6\%

Therefore the percentage change in volume is \pm 6\%

AnnyKZ [126]

Answer:

1.L_s=0.0076\ m

2.L_l=7.62\ m

Explanation:

Given that

f₁= 20 Hz

f₂= 20 KHz

C= 305 m/s

For open pie organ :

L=\dfrac{C}{2f}

<u>Shortest length :</u><u> </u>

L_s=\dfrac{C}{2f_2}

L_s=\dfrac{305}{2\times 20000}

L_s=0.0076\ m

<u>Longest length : </u>

L_l=\dfrac{C}{2f_1}

L_l=\dfrac{305}{2\times 20}

L_l=7.62\ m
