Answer:
The incidence angle is 27°
Explanation:
As the complete question is not given, the complete question is given here
<em>The angle between the Sun and a rescue aircraft is 54 degrees. What should be the angle of incidence for sunlight on a plane mirror so that the rescue pilot sees the reflected light?</em>
From the question, the total angle between the Sun and the aircraft is 54 degrees which is the sum of the incidence and the reflected angle so
Also from the law of reflection
So now the equation becomes
So the incidence angle is 27°
Answer:
3 orbitals
Explanation:
The p sublevel can carry a maximum of 6 electrons. Therefore it must be made of 3 orbitals which each, as in any orbital of any other sublevel, can carry 2 electrons. So there is a p sub x orbital, p sub y orbital and p sub z orbital which are all orthogonal to each other.
The controlled variable is the one that you keep constant. The responding variable or variables is what happens as a result of the experiment (i.e. it's the output variable).
Answer:
T = 53.44 ° C
Explanation:
For this exercise we will use the relationship between the speed of sound and the wavelength and frequency
v = λ f
v = 0.285 1270
v = 361.95 m / s
The speed of sound is related to temperature in degrees Celsius
v = 331 √(1 + T / 273)
v² / 331² = 1 + T / 273
T / 273 = v² / 331² -1
T = 273 (v² / 331² -1)
Let's calculate
T = 273 (361.95²/331² -1)
T = 53.44 ° C
I believe the correct answer from the choices listed above is option 4. Base from the passage given above, it is very clear that the Campylobacter is a bacteria used to test in <span>identifying drug-resistant bacteria. Hope this answers the question. Have a nice day.</span>
