Answer:

Temperature, T = 1542.10 K

Explanation:

It is given that,

The black body radiation emitted from a furnace peaks at a wavelength of, \lambda=1.9\times 10^{-6}\ m

We need to find the temperature inside the furnace. The relationship between the temperature and the wavelength is given by Wein's law i.e.

\lambda\propto \dfrac{1}{T}

or

\lambda=\dfrac{b}{T}

b = Wein's displacement constant

\lambda=\dfrac{2.93\times 10^{-3}}{T}

T=\dfrac{2.93\times 10^{-3}}{\lambda}

T=\dfrac{2.93\times 10^{-3}}{1.9\times 10^{-6}\ m}

T = 1542.10 K

So, the temperature inside the furnace is 1542.10 K. Hence, this is the required solution.

Identify the type of chemical reaction that is described.
Anastasy [175]

Water breaks down into  hydrogen and oxygen: It is a decomposition reaction as a single substance decomposes to give two products.

H_2O \rightarrow H_2 +\frac {1}{2}O_2

Leaves make starch using  chlorophyll and carbon dioxide: Synthesis reaction: as the synthesis reaction involves two or more than two reactants which join together to result into a single main product along with the formation of simple by products.

6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2

Food burns in oxygen gas  and releases a lot of energy: Combustion: Combustion process involves the use of oxygen to give products along with release of energy.

C_6H_{12}O_6 + 6O_2\rightarrow 6CO_2 + 6H_2O

Adding vinegar (acid) to baking soda (alkali) gives  a product that is neither  acidic nor alkaline: Neutralization: acetic acid in vinegar reacts with soda (base) to give salt (neutral) and .

CH_3COOH + NaHCO_3\rightarrow CH_3COONa +H_2O + CO_2

A wave traveling in a string has a wavelength of 35 cm, an amplitude of 8.4 cm, and a period of 1.2 s. what is the speed of this
kifflom [539]

The equation will be of the given statement:

y(x,t)  = (0.084)sin(18x - 5.2t)

<h3>What is Wavelength?</h3>

The distance a wave travels from one crest to another or from one trough to another is known as its wavelength (which may be an electromagnetic wave, a sound wave, or any other wave). The peak of the wave is called the crest, while the trough is its base.

<h3>According to the given information:</h3>

wavelength  = 35cm = .35m

amplitude A =  8.4 cm

Time  = 1.2s

The speed of this wave:

In the positive x direction, the wave is moving in a string. For these circumstances, we must write the wave equation.

When the wave is moving in the +x direction, the following general equation describes it:

Y = Asin( kx - wt )

A is amplitude

k is propagation constant

k = 2π/λ

k = 2π/0.35

k = 17.95 = 18m^-1

ω is angular frequency

ω = 2π/T

ω = 2π/1.2

ω = 5.23s^-1

The equation will be:

y(x,t)  = (0.084)sin(18x - 5.2t)
