We need to use Wien's Law
Wavelength = 0.0028976 [m.K] / T
This establishes a relation between the wavelength and temperature of a black body (any body that absorbs radiation, such as the stars)
T = 0.0028976 [m.K]/290 E-9[m] = 9991.724 K
Answer:
xxxxx
Explanation:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a Volume (the same volume as 1 milliliter).
Answer:
Not between significant digits.
Explanation:
A zero not significant when it's not between significant digits.
A heat engine would be less efficient due to many factors
For instance, a heat engine is more efficient when it uses in cold weather because there is a greater temperature difference ( Carnot Efficient )
A heat engine could be less efficient because of friction
