Answers:(a) 
μT
(b) 
μm
(c) f = 
 Explanation:
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 = 
 
 
        
             
        
        
        
Answer:
The current lags the potential difference by π/2 in an inductor
Explanation:
The potential difference leads to the current by   . Alternate signals such as current and voltage -in this case- are periodic, this means that this signals are repeated at fixed spaces of time. Thus, In an inductor the current lags the potential difference by

Answer:
(D)
to establish an understanding of key concepts relating to population biology
Explanation:
Thats what I would go with but I didn't read the article so I don't know what context was used. Good luck! :)
 
        
             
        
        
        
I think the correct answer is D: Potential Energy.
