One of the handy formulas for the power dissipated by
a circuit element is
Power = (current)² x (resistance) .
That certainly seems to be the one to use for this problem,
since we're given the power and the current, and we're asked
to find the resistance.
Power = (current)² x (resistance) .
Divide each side by (current)² :
Resistance = (power) / (current)²
Resistance = (1200W) / (11 A)²
Resistance = 1200 / 121 = <em>9.917... ohms</em> (rounded)
Answer:
35°
Explanation:
By laws of reflection,
Angle of incidence = Angle of reflection
Angle between incident ray and reflected ray = 70°
Angle of incidence + Angle of reflection = 70°
Since,
Angle of incidence = Angle of reflection
Angle of incidence + Angle of incidence = 70°
2 Angle of incidence = 70°
Divide 2 on both sides,
Angle of incidence = 70° / 2
Angle of incidence = 35°
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.

- The complexity of Earth is beyond the capabilities of computer simulations.
- Numerous assumptions that must be made by computer models have a big impact on the forecasts they produce.
- A computer model can incorporate historical climate data, but it is not possible to draw assumptions about future climates using this data in any way.
- A computer model cannot distinguish between anthropogenic climate change and natural climatic fluctuations.
<h3>How precise are temperature forecasts made by climate models?</h3>
The forecasting of global surface temperatures is one of the most significant results of climate models.
Scientists evaluate the effectiveness of their models by contrasting observations of the Earth's climate with predictions of future temperatures and "hindcasts" of past temperatures. Then, by comparing specific climate models and the average of all models to actual warming, scientists may determine whether temperature projections are accurate.
Researchers can have more faith that models can effectively predict future changes in the same factors if they successfully simulate the climate response in the past.
