The temperature at the surface of the Sun is approximately 5,300 K, and the temperature at the surface of the Earth is approxima
N76 [4]

Answer:

The entropy change of the Universe that occurs is 19.346 J/K

Explanation:

Given;

temperature of the sun, T_s = 5,300 K

temperature of the Earth, T_E = 293 K

radiation energy transferred by the sun to the earth, E = 6000 J

The sun loses Q of heat and therefore decreases its entropy by the amount

\delta S_{sun} = \frac{-Q}{T_s}

The earth gains Q of heat and therefore increases its entropy by the amount

\delta S_{Earth} = \frac{-Q}{T_E}

The total entropy change is:

\delta S_{Earth} + \delta S_{sun} = \frac{Q}{T_E} -\frac{Q}{T_S} \\\\                                                      = Q(\frac{1}{T_E} -\frac{1}{T_S} )\\\\= 6000(\frac{1}{293} -\frac{1}{5300} )\\\\=6000(0.0032243)\\\\= 19.346 \ J/K

Therefore, the entropy change of the Universe that occurs is 19.346 J/K

The speed of sound in air is approximately 350 m/s. You are sitting in a canyon with cliffs 525 m from you. You clap your hands.
Wewaii [24]

Answer:

3 s.

Explanation:

Echo is defined as the repetition of a sound produced by the reflection of sound waves from an obstructing surface like a wall, mountain etc.

v = f*lambda

Where,

Lambda = wavelength of the wave

f = frequency of the wave = 1/t

v = velocity of the wave.

Distance there and back = initial ditance * 2

= 525 x 2

= 1050.

Time taken, t = lamda/velocity

= 1050 / 350

= 3 s.

So the delay is 3 seconds.

If a wave traveling through air decreases its wavelength by half, describe what happens to the wave speed and frequency.
natka813 [3]
The frequency, the speed and the wavelength of a wave are related by the following equation:
f= \frac{v}{\lambda} (1)
where
f is the frequency
\lambda is the wavelength
v is the wave speed

The speed of the wave does depend only on the properties of the medium, so since the wave is still traveling in air, the medium has not changed and therefore the speed remains the same. We see instead from eq.(1) that the frequency is inversely proportional to the wavelength, so if the wavelength is decreased by half, we see that the frequency will double.
