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:
C . All of the different types of electromagnetic waves
Answer:
The amount of work is 89600 ft-lb.
Explanation:
Given that,
Length of the cable = 160 ft
Weight density = 7 lb/ft
Weight of cable to be filled = 7(160-x)
We need to calculate the amount of work
Using formula of work done
On integration
Hence, The amount of work is 89600 ft-lb.
Answer:
1.49 m/s
Explanation:
The average speed is:
Where v is speed, s is distance and t is time. We are given with a distance of 18 km and time is 3.36 hours.
We'll be converting from km to meters and hours to seconds as standard unit for speed is m/s.
To convert the unit from kilometer to meter, we know that 1 kilometer equals to 1000 meters. Therefore, 18 kilometers will equal to 1000 * 18 meters which will equal to 18000 meters total.
To convert from hour to second, we know that 1 hour equals to 60 minutes. Therefore, 3.36 hours will equal to 60 * 3.36 = 201.6 minutes.
A minute equals to 60 seconds. Therefore, 201.6 minutes equal to 60 * 201.6 = 12096 seconds.
Finally, we have units in meter and second. We'll be able to calculate for average speed now by applying the formula above:
Therefore, Serina's average speed will be around 1.49 m/s
