Answer:
The angle between the vector and positive x-axis is approximately 59.036º.
Explanation:
By Linear Algebra and to be precise, by definition of Dot Product we can determine the angle between two vector from following expression:
(1)
Where:
,
- Vectors, no unit.
,
- Norms of vectors, no unit.
- Angle, measured in sexagesimal degrees.
Please notice that norms are calculated by Pythagorean Theorem. If we know that and
, then the angle between the vector and positive x-axis is:
The angle between the vector and positive x-axis is approximately 59.036º.
Answer:
A = 1.41 m²
Explanation:
The ara can be found out by using Stefan Boltzman Law:
where,
A = Area = ?
P = Radiation Power = 1200 W
σ = Stefan Boltzman Constant = 5.6703 x 10⁻⁸ W/m².k⁴
T = surface temperature = 350 k
Therefore:
<u>A = 1.41 m²</u>
