Jack tries to place magnets on his refrigerator at home, but they won’t stick. What could be the reason?
saul85 [17]
The most probable reason why the magnets won't stick on the refrigerator is that the body of the refrigerator and the magnets have like poles. If both have negative or both have positive poles facing each other, they will repel. In principle, magnets are attracted to opposite poles and like poles repel.

The peak wavelength of light coming from a giant red star is 660 nm. Calculate the approximate surface temperature of this star
laiz [17]

Answer:

The value is T =260.33 \ F

Explanation:

From the question we are told that  

  The the peak wavelength is  \lambda_p =  660 nm = 660 *10^{-9} \  m

 Generally according to the Wien's displacement law

       \lambda_p *  T =  2.898*10^{-3} \ m \cdot K  

Here T is the approximate surface temperature of this star in K so

       660*10^{-9} *  T =  2.898*10^{-3} \ m \cdot K  

=>    T =  4091 \  K

Converting to Fahrenheit ,

     T = [400 - 273.15 ] * \frac{9}{5} + 32

=>  T =260.33 \ F
