Radiation emitted from human skin reaches its peak at λ = 960 µm. what is the frequency of this radiation? planck's constant is
Artist 52 [7]
1) The wavelength of the radiation emitted by the human skin is
\lambda=960 \mu m = 960 \cdot 10^{-6} m
the frequency of the radiation is related to the wavelength by
f= \frac{c}{\lambda}
where c=3 \cdot 10^8 m/s is the speed of light. Plugging numbers into the formula, we find the frequency of the radiation:
f= \frac{3 \cdot 10^8 m/s}{960 \cdot 10^{-6}m}=3.13 \cdot 10^{11} Hz

2) The frequency of this radiation is 313 GHz, and its wavelength 960 \mu m. If we look at the table of the electromagnetic spectrum
https://en.wikipedia.org/wiki/Electromagnetic_spectrum
We see that we are in the range of visible light (in particular, in the infrared range).
Therefore, the correct answer is <span>2. visible light .</span>

a. Find the magnitude of the gravitational force (in N) between a planet with mass 6.50 ✕ 1024 kg and its moon, with mass 2.45 ✕
Vanyuwa [196]

Answer:

a. 1.70\times 10^{20} N b. 6.94\times 10^{-3}m/s^2 c. 2.62\times 10^{-5} m/s^2

Explanation:

Use Gravitational Force:

F= G\frac{Mm}{r^2}

Use values given to have the results.

b.

g=\frac{F}{m}

Use m as the mass of the Moon. Using values of a. and m you have the answer.

c.

g = \frac{F}{M}

Use M mass of the planet. Use value of a and Mass of Planet.
