Answer:

4.5 x 10⁻6m

Explanation:

<em>From the formula given,</em>

<em>ʎ/d = x/L</em>

<em>The wavelength of 750 nm will be: 750 x 10⁻⁹ / 2.0 x 10⁻³ 3 =  x/ 2.0 </em>

<em> Now</em>

<em>50 x 10⁻⁹ / 2.0 x 10⁻³ 3 =  x 2.0  = x = 7.5 x 10⁻⁴m</em>

<em>The wavelength of 900 nm  will be:  900 x 10 ⁻⁹ / 2.0 x 10⁻³ = x /2.0 </em>

<em> 00 x 10 ⁻⁹ / 2.0 x 10⁻³ = x /2.0 = x = 9.0 x 10⁻⁴</em>

<em>Then</em>

<em>9.0  x 10⁻⁴ / 7.5 x 10⁻⁴ = 1.2</em>

<em>to get to the first integer, 1.3 must be 1.2  is the multiplied  5 times t (which will be a fringe (bright)) which is 6. </em>

<em>Therefore, what this mean is there will be 6 fringes of wavelength 750 nm and 5 fringes of wavelength 900 nm .</em>

<em>From the central brightest fringe.  the mixing fringe will be  4.5 x 10⁻6m  or 4500 nm .</em>

blondinia [14]

Answer: Enceladus

Explanation:

Enceladus is a small, icy body with an undergound ocean beneath its crust. Cassini discovered that geyser-like jets spew water vapor and ice particles. It is also the sixth largest moon in Saturn and just about a tenth of the largest moon in Saturn; Titan. It is often regarded as one of the most reflective body in the solar system as a result of its icy surface.

How are electrical signals transmitted over long distances?
forsale [732]

Answer:

Over such small distances, digital data may be transmitted as direct, two-level electrical signals over simple copper conductors. This results from the electrical distortion of signals traveling through long conductors, and from noise added to the signal as it propagates through a transmission medium.

A skier leaves the horizontal end of a ramp with a velocity of 31.0 m/s and lands 156.3 m from the base of a ramp how high is th
BartSMP [9]

<u>Answer:</u>

The height of ramp = 124.694 m

<u>Explanation:</u>

Using second equation of motion,

s = ut + \frac{1}{2}at^2

From the question,

u = 31 m/s; s = 156.3 m, a=0

substituting values

156.3 = 31\times t + 0

t = \frac{156.3}{31 }

= 5.042 s

Similary, for the case of landing

t = 5.042 s; initial velocity, u =0

acceleration = acceleration due to gravity, g = 9.81 m/s^2

Substituting in h = ut + \frac{1}{2}gt^2

h = 0 + \frac{1}{2} \times 9.81 \times (5.042)^2

h = 124.694 m

So height of ramp = 124.694 m

4A. How high is a 12 kg monkey in a tree if it has 509 J of gravitational potential Energy?
True [87]

4A. PE = MxGxH. (You can consider g as 9.8 / 10m/s as well)

509 J = 12x10xH

509 J = 120xH

H = 509/120

H = 4.24 m

Hope u got the answer....pls rate the answer if it is helpful for u....and I'm sorry I could not understand B part so I didn't do it.

Thank you

Airida [17]

Answer:

\frac{I}{I_0}=113.68

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

P=IA\\\Rightarrow I=\frac{P}{A}\\\Rightarrow I=\frac{63\times 10^{-6}}{4\times \pi \times 210^2}

Threshold intensity = I_0=1\times 10^{-12}\ W/m^2

Ratio

\frac{I}{I_0}=\frac{\frac{63\times 10^{-6}}{4\times \pi \times 210^2}}{1\times 10^{-12}}\\\Rightarrow \frac{I}{I_0}=113.68

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68
