Statement three i do believe
Answer:
a

b

c

d

Explanation:
From the question we are told that
The frequency of the radio station is 
The magnitude of the magnetic field is 
Generally the wavelength is mathematically represented as

Here c is the speed of light with value 
So

=> 
Generally the angular frequency is mathematically represented as

=> 
=> 
Generally the wave number is mathematically represented as
=> 
=> 
=> 
Generally the amplitude of the electric field at this distance from the transmitter is mathematically represented as

=> 
=> 
Answer:
12.25 meters
Explanation:
s=1/2(v+u)t
s= displacement
v= final velocity
u= initial velocity
t= time
7m/s+0m/s divide by 2= 3.5 m/s velocity Times 3.5 seconds= 12.25 meters
Answer:
10 watts
Explanation:
first calculate work.
Work =force×distance cos thita
10Kg×0.50M cos 0= 5joules
Therefore, Power=Work÷ Time
Therefore, 5joules÷0.50s=10 watts.
