Wien's law describes the wavelength of maximum intensity λ max for a blackbody at a particular temperature t: wien's law: λ max ⋅ t = 2.90 × 10 − 3 m ⋅ k if we measure the temperature of a blackbody to be about 300 k (a typical air temperature in florida), at what wavelength would this blackbody's intensity have its maximum, and where in the electromagnetic spectrum is this wavelength?

Explanation:

The mathematical expression for Wein's law is given by :

Where

T is the temperature

is the wavelength

At T = 300 K

So, the wavelength of black body is and this wavelength lies in infrared region of the spectrum. Hence, this is the required solution.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
