1a) a blackbody has a peak wavelength of 1.45 x10^-6m. what is its surface temperature? (be sure to include units in your answer)
b)a black body has a temperature of 4000k. at what wavelength does its spectrum peak? (include units in your answer)
c) a black body has a peak emission of 4.83 x 10^-7m. what is its surface temperature? be sure to include units.
d)star a has a temperature of 3000k. star b has a temperature of 6000k. star b radiates x more energy than star a

Ashould be answer.

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
