Answer:
Look at the mirror from the positive axis and suppose the incident ray is at angle at 40 from the y-axis
Incident ray at 50 deg
reflected ray at 130 deg
total angle of deflection = 130 - 50 = 80 deg
Now rotate the mirror by 20 deg
incident ray at 30 deg
reflected ray at 150 deg (angle of incidence must equal angle of reflection)
total angle of deflection = 150 - 30 = 120 deg
the difference between 2 reflected rays = 120 - 80 = 40 deg
So if you increase (decrease) the incident angle the reflected ray will be increased by twice the angle of rotation of the mirror - or the perpendicular to the mirror increases by X degrees the angles of incidence and reflection will each increase by X deg
Answer:
= -8πx![10^{-7}](https://tex.z-dn.net/?f=10%5E%7B-7%7D)
Explanation:
If you need calculate
![\begin{equation}\\\oint_L B.dl\\ \end{equation}](https://tex.z-dn.net/?f=%5Cbegin%7Bequation%7D%5C%5C%5Coint_L%20B.dl%5C%5C%20%5Cend%7Bequation%7D)
You can use the Ampere's Law
=
μ
Where
: Current passing through the window
μ : Free space’s magnetic permeability
μ = 4πx![10^{-7} T.m.A^{-1}](https://tex.z-dn.net/?f=10%5E%7B-7%7D%20T.m.A%5E%7B-1%7D)
Then
= (3-5)4πx![10^{-7}](https://tex.z-dn.net/?f=10%5E%7B-7%7D)
= -8πx![10^{-7}](https://tex.z-dn.net/?f=10%5E%7B-7%7D)
Answer:
3520
Explanation: Force = Mass x Acceleration [∴ or F = ma]. Given values. mass, m = 1600 kg; initial velocity, u = 8 m/s; final velocity, v = 30 m/s; time taken, t = 10 s.
Answer:
La ciencia y la tecnología se complementan porque la tecnología necesita que la ciencia sea una cosa y la ciencia se usa en tecnología
Explanation:
This is called the restoring force.
