Within the visible spectrum, our experience of red is associated with a <u>longer wavelength </u>of light.

<h3>What is the electromagnetic spectrum?</h3>

The electromagnetic spectrum is seen as colors: violet, indigo, blue, green, yellow, orange, and red. Blue light has a very short wavelength, and so produces a higher amount of energy.

In the visible spectrum, the longer wavelengths that we perceive as red are followed by intermediate wavelengths for green and shorter wavelengths for blue and violet.

Our perception of red is connected to a longer wavelength of light within the visible spectrum.

Hence longer wavelength is the correct answer for blanks.

Answer:

K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹

Explanation:

Rate of flow of heat through a material is given by the following expression

$\frac{Q}{t} =\frac{KA\delta T}{d}$

where Q is amount of heat flowing in time t through area A and a medium of thickness d having two faces at temperature difference δT . K is thermal conductivity of the medium .

Here Q = 3.34 x 10⁶/6 , t = 24 x 60 x 60 = 86400 s , A = .332 X .332 = .0110224 m² , δT = 104.7

Put these values here

$\frac{3.34\times10^6}{6\times86400}= \frac{k\times.011224\times104.7}{4.41\times10^{-2}}$

$K=\frac{3.34\times4.41\times10^4}{6\times86400\times.011224\times104.7}$

K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹

Your toaster has a power cord with a resistance of 2.2x10^−2 Ω connected in series with a 9.7 Ω nichrome heating element. The po

kati45 [8]

Answer:

(A) 654.545 Kw

(B) $2.885\times 10^5kw$

Explanation:

We have given resistance of the toaster $R_1=2.2\times 10^{-2}ohm=0.022ohm$

Resistance of nichrome heating element $R_2=9.7ohm$

Both the resistances are connected in series so same current will flow through the circuit

Potential difference across the toaster V = 120 volt

So current $i=\frac{120}{0.022}=5454.5454A$

(a) Power dissipated in toaster $P=i^2R=5454.5454^2\times 0.022=654545.441W=654.545kw$

(B) Power dissipated in heating element $P=i^2R=5454.5454^2\times 9.7=2.885\times 10^8W=2.885\times 10^5kw$

Which of these accurately identify characteristics of light and mechanical waves? Select the TWO (2) that apply.

Tanzania [10]

The two correct statement are A and B. Light waves are electromagnetic waves that can travel through a vacuum. Mechanical waves can travel through a vacuum.

<h3>What is an electromagnetic wave?</h3>

EM waves are the electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field.

Electromagnetic waves may alternatively be defined as the combination of oscillating electric and magnetic fields.

Electrically charged particles experiencing acceleration create electromagnetic waves, which can then interact with other charged particles and exert force on them.

The two correct statement is;

1. Light waves are electromagnetic waves that can travel through a vacuum.

2. Mechanical waves can travel through a vacuum.

Hence,two correct statement are A and B.
