Answer:
Current = 10 Amperes.
Explanation:
Given the following dat;
Quantity of charge, Q = 36 kilocoulombs (KC) = 36 * 1000 = 36000C
Time = 1 hour to seconds = 60*60 = 3600 seconds
To find the current;
Quantity of charge = current * time
Substituting in the equation
36000 = current * 3600
Current = 36000/3600
Current = 10 Amperes.
Answer:
15.19°, 31.61°, 51.84°
Explanation:
We need to fin the angle for m=1,2,3
We know that the expression for wavelenght is,
![\lambda = \frac{c}{f}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7Bc%7D%7Bf%7D)
Substituting,
![\lambda = \frac{344}{1250}](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B344%7D%7B1250%7D)
![\lambda = 0.2752m](https://tex.z-dn.net/?f=%5Clambda%20%3D%200.2752m)
Once we have the wavelenght we can find the angle by the equation of the single slit difraction,
![sin\theta = \frac{m \lambda}{W}](https://tex.z-dn.net/?f=sin%5Ctheta%20%3D%20%5Cfrac%7Bm%20%5Clambda%7D%7BW%7D)
Where,
W is the width
m is the integer
the wavelenght
Re-arrange the expression,
![\theta = sin^{-1} \frac{m\lambda}{W}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%20%5Cfrac%7Bm%5Clambda%7D%7BW%7D)
For m=1,
![\theta = sin^{-1} \frac{1 (0.2752)}{1.05}= 15.19\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%20%5Cfrac%7B1%20%280.2752%29%7D%7B1.05%7D%3D%2015.19%5C%C2%B0)
For m=2,
![\theta = sin^{-1} \frac{2 (0.2752)}{1.05}= 31.61\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%20%5Cfrac%7B2%20%280.2752%29%7D%7B1.05%7D%3D%2031.61%5C%C2%B0)
For m=3,
![\theta = sin^{-1} \frac{3 (0.2752)}{1.05}= 51.84\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%20%5Cfrac%7B3%20%280.2752%29%7D%7B1.05%7D%3D%2051.84%5C%C2%B0)
<em>The angle of diffraction is directly proportional to the size of the wavelength.</em>
Answer:
100N
Explanation:
Newton's third law of motion
For every action, there is an equal and opposite reaction.
Therefore 100N of force is exerted by the crate on student as a reaction to his action
Answer:
a) θ₁ = 23.14 °
, b) θ₂ = 51.81 °
Explanation:
An address network is described by the expression
d sin θ = m λ
Where is the distance between lines, λ is the wavelength and m is the order of the spectrum
The distance between one lines, we can find used a rule of proportions
d = 1/600
d = 1.67 10⁻³ mm
d = 1-67 10⁻³ m
Let's calculate the angle
sin θ = m λ / d
θ = sin⁻¹ (m λ / d)
First order
θ₁ = sin⁻¹ (1 6.5628 10⁻⁷ / 1.67 10⁻⁶)
θ₁ = sin⁻¹ (3.93 10⁻¹)
θ₁ = 23.14 °
Second order
θ₂ = sin⁻¹ (2 6.5628 10⁻⁷ / 1.67 10⁻⁶)
θ₂ = sin⁻¹ (0.786)
θ₂ = 51.81 °
