Answer:
Correct answer is 2B
Explanation:
The electric field magnitude and magnetic field magnitude in an electromagnetic waves are related as under
where 'c' is velocity of light in the medium of transmission
According to the given question if we double the electric field we have
Thus the magnetic field also doubles

such as, death, birth defects, asthmea, breathing conditions, increased diseases.
An example of using muscular strength would be doing things like lifting weights and things like that.
Answer:
<h2>Tt will take 4.04 seconds</h2>
Explanation:
In this problem/exercise, we are going to apply the newtons first equation of motion to solve for the time taken
Given that
final velocity= 3.4m/s
initia velocity u= 0m/s
deceleration= 0.84 m/s^2
time t= ?
applying
v=u+at
Substituting our given data into the expression above we have
3.4=0+0.84t
3.4=0.84t
divide both sides by 0.84 we have
3.4/0.84= t
t= 4.04 seconds
