Explanation:Given electric field(in y direction) equation:

(a) The amplitude of electric field is

. Hence
The amplitude of magnetic field oscillations is

Where c = speed of light
Therefore,

μT (Where T is in seconds--signifies the oscillations)
(b) To find the wavelength use:



μm
(c) Since c = fλ
=> f = c/λ
Now plug-in the values
f = (3*10^8)/(0.4488*10^-6)
f =
Impulse = change of momentum
Impulse = 45 x 6 = 270 Ns

Answer:


Explanation:
<u>Data</u>
<u>mass m= 100g</u>
<u>Length L= 5cm</u>
<u>we can use:</u>
<u>gm-kL= 0</u>
<u>divide both side by m</u>
<u>g - </u>
<u>=0</u>
<u>where</u>
= 
^{2}
so now
= 


square both side


We can apply:
u(t)=Acoswt +Bsinwt
u(t)=Acos14t +Bsin14t
u(0)=0 where A=0
therefore
u(0) = Bsin14t
(0) = 10 ⇒ 10=14B ⇒ B=
B=
so now u(t)=
sin14t
so t will be:
t=
t=
t=0.22 seconds
