EM waves travel at the same speed in all settings.
however their wavelength will be different as the frequency is different.
we know, v = f x lambda,
v is determined by the medium
At low wind speed, more blades will be better and the blades should be long and wide. The blade pitch should be large. At high wind speed, the blades should be short and thin. The blade pitch should be small then.
Answer:
final volume = 640 ml
Explanation:
To answer this question, we will use Boyle's law which states that:
"At constant temperature, the product of the pressure and the volume of a given mass of gas will be constant"
Thereore:
P1V1 = P2V2
800*560 = 700*V2
V2 = 640 ml
Hope this helps :)
