Answer:
1.0s
Explanation:
distance = 1/2 × acceleration × time2 + intial speed × time
Answer:
The corresponding magnetic field is
Explanation:
From the question we are told that
The electric field amplitude is 
Generally the magnetic field amplitude is mathematically represented as

Where c is the speed of light with a constant value

So


Since 1 T is equivalent to 

Wave speed = (wavelength) x (frequency)
= (4 m) x (2 /sec)
= 8 m/sec
The same speed of light, the fastest possible
darkness is just the absence of light therefore once light leaves darkness returns. making darkness have the same speed of light
