The answer is B, <span>angular diameter. </span>
Because if there's no force on the object, then it just moves in a straight line.
I think the correct answer from the choices listed above is the first option. One of the challenges of wind power is the <span>location of wind farms. Wind farms require large areas in order to function. It consumes a lot of space. Hope this answers the question.</span>
To find the internal energy of gas we can use
here given that
Number of moles (n) = 7 moles
Temperature T = 40 + 273 = 313 K
degree of freedom(f) = 5 (for diatomic gas)
now by above formula
<em>So it is approximately 45500 J (option C)</em>
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°
