Answer:
wave number = 0.3348 * 10⁻⁸ cm⁻¹
Explanation:
Given data:
K = 4.808 * 10^2 N/m
<u>Determine the wave number for the infrared absorption</u>
considering vibrational Spectre
k' = 2n / λ ---- ( 1 )
λ = c / v ----- ( 2 )
v = √k / u --- ( 3 )
where : k' = wave number, λ = wavelength, c = velocity of light, v = frequency, k = force constant, u = reduced mass
u = 1.90415 for D35Cl
Input equations 2 and 3 into equation 1 to get the final equation
K' = 2n/c * √k / u
= ( 2 * 3.14 ) / 2.98 * 10^8 ] * (√ 4.808 * 10^2 / 1.90415 )
= 33.486 * 10⁻⁸ m⁻¹ ≈ 0.3348 * 10⁻⁸ cm⁻¹
Explanation:
B. All use generators to produce electrical current
Answer:
Fm - W = 0 1) true. Imams must separate, to match the two forces, you reach equilibrium
Explanation:
When the magnet is exchanged for a stronger one, but of the same weight, the equilibrium equation
Fm - W = 0
Fm = W
If the weight of the imam is the same, the magnetite force must decrease, so that it will occupy the magnets must be separated a greater distance, according to the formula
Fm = Km m ’m / r²
Where Km is value 10⁻⁷ N s²/C², r is the distance between the poles
Let's review the proposed results
1) true. Imams must separate, to match the two forces, you reach equilibrium
2) False. In this case the weight would be less than the magnetic force
3) False The magnetic force increases and equilibrium is not reached
Answer:
c is the correct answer

![\frac{d_2}{d_1} = \sqrt2 = 1.41](https://tex.z-dn.net/?f=%5Cfrac%7Bd_2%7D%7Bd_1%7D%20%3D%20%5Csqrt2%20%3D%201.41)
Explanation:
As resistor is connected to the battery of constant EMF then the power across the resistor is given as
![P = \frac{E^2}{R}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BE%5E2%7D%7BR%7D)
now if two resistors are made up of same material and of same length then due to different cross sectional area they both have different resistance
Due to different resistance they both will have different power
Since power is inversely depends on the resistance
So if the power is twice that of the other then the resistance must be half
so we have
![R_1 = \rho \frac{L}{A_1}](https://tex.z-dn.net/?f=R_1%20%3D%20%5Crho%20%5Cfrac%7BL%7D%7BA_1%7D)
![R_2 = \rho\frac{L}{A_2}](https://tex.z-dn.net/?f=R_2%20%3D%20%5Crho%5Cfrac%7BL%7D%7BA_2%7D)
since one resistance is half that of other resistance
So the area of one must be twice that of other
so we have
![\frac{A_2}{A_1} = 2](https://tex.z-dn.net/?f=%5Cfrac%7BA_2%7D%7BA_1%7D%20%3D%202)
![\frac{\pi d_2^2}{\pi d_1^2} = 2](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20d_2%5E2%7D%7B%5Cpi%20d_1%5E2%7D%20%3D%202)
![d_2 = 1.41 d_1](https://tex.z-dn.net/?f=d_2%20%3D%201.41%20d_1)
