Product of my research: 1 HP = 746 watts .
12 HP = (12 x 746 W) = 8,952 W
8,952 W = 8.952 kW
Answer:
(a) 1.029 m
(b) 1.78 mm
Solution:
As per the question:
Wavelength of light,
Slit width, w = 0.68 mm
Now,
The distance first minimum in the diffraction pattern,
Now,
(a) For first minima:
where
D = Distance from the screen
D = 1.029 m
(b) The width of the central maxima is given by:
2y =
The correct answer is "decrease":
<span>A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will INCREASE the wavelength.
Let's see why. The basic relationship between frequency and wavelength of a wave is
</span>
<span>where
v is the speed of the wave
f its frequency
</span>
its wavelength
<span>
We can see from this equation that, if the frequency is increased, if the speed of the wave does not change (and this is the case), then the wavelength of the wave must decrease, since the ratio </span>
becomes smaller.
