The solution would be like this for this specific problem:
Given: 5973 K
λ_peak = 2.898 / 5973 K
= 0.00048518 mm = 0.48518 μ = 4851.8 Ậ
Polaris emits peak radiation at 485 nm wavelength.
To add, Polaris, commonly the North Star or Pole
Star, is the brightest star in the constellation of Ursa Minor.
Answer:
Explanation:
Given that,
Displacement in North = 11 km
Displacement in East = 11 km
We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :
Hence, the approximate displacement of the hiker from the camp is .
K.E = 0.5 * m * v^2
= 0.5 * 80 * (1.5)^2
K.E = 90 joule
