Using wien’s law, estimate the wavelength at which these common materials radiate their peak brightness (show your work):

walls at 300 k:

ice water at 273 k :

hot water at 373 k :

skin at 310 k:

an incandescent light bulb at 3000 k

Explanation:

Wien’s Law:

The law states that the wavelength at which black body emits maximum heat  is inversely proportional to the temperature of the body in Kelvins.

1) Walls at 300 K

2) Ice water at 273 K :

3) Hot water at 373 K :

4)Skin at 310 K:

5)An incandescent light bulb at 3000 K

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.
