Answer:
n = 3
Explanation:
We know that the nth-order maximum for the Young's two-slit experiment is given by the following expression:
dsin(θ) = nλ
If two maxima concides we must have the relation:
nλ1 = mλ2 --- eq1
In this particular experiment
m = n+1
λ1 = 680 nm
λ2 = 510 nm
Replacing m in eq1 we have
nλ1 = (n+1)λ2
Solving for n we have:
n = λ2/(λ1-λ2)
Therefore:
n = 510/(680-510)=3
Answer:
![E = 1.95 \times 10^{-4} J](https://tex.z-dn.net/?f=E%20%3D%201.95%20%5Ctimes%2010%5E%7B-4%7D%20J)
Explanation:
As we know that the mass of the fleas is given as
![m = 3.9 \times 10^{-4} kg](https://tex.z-dn.net/?f=m%20%3D%203.9%20%5Ctimes%2010%5E%7B-4%7D%20kg)
now the speed of the fleas is given as
![v = 1 m/s](https://tex.z-dn.net/?f=v%20%3D%201%20m%2Fs)
now just before it will jump let say it has some energy E
so as per energy conservation law we can say that this total initial energy will convert into its kinetic energy just after the jump
so the initial total energy is given as
![E = \frac{1}{2}mv^2](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
![E = \frac{1}{2}(3.9 \times 10^{-4})(1^2)](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B1%7D%7B2%7D%283.9%20%5Ctimes%2010%5E%7B-4%7D%29%281%5E2%29)
![E = 1.95 \times 10^{-4} J](https://tex.z-dn.net/?f=E%20%3D%201.95%20%5Ctimes%2010%5E%7B-4%7D%20J)
I believe it is A. Just don't hold me down on that. :D
The angle of the planet is mathematically given as
dY= 704 degrees
<h3>What angle has planet Y rotated through during this time?</h3>
With Kepler's third rule, which states that a planet's orbit squared is a function of cubed radius, we can prove that this is the case.
Generally, the equation for the period is mathematically given as
(periodX / periodY)^2 = (radius X / radius Y)^3
Therefore
(pX / pY)^2 = 4^3
(pX / pY)^2 = 64
\sqrt{(pX / pY )^2}= \sqrt{64}
(pX / pY=8
In conclusion, Because it takes 8 times longer to complete one orbit on planet X, planet Y travels 8 times farther than planet X does in the same time period...
planet Y travels ;
dY=8 * 88.0
dY= 704 degrees
