Answer:
B = Bo / 2
Explanation:
Magnesium and electric fields are related in an electromagnetic wave
E / B = c
If the electric field is halved the magnetic field must also be halved to meet the written equation
B = Bo / 2
A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Answer:
<h2>
16,931 turns</h2>
Explanation:
The magnetic field produced is expressed using the formula

B is the magnetic field = 0.30T
I is the current produced in the coil = 4.5A
is the magnetic permittivity in vacuum = 1.26*10^-6Tm/A
L is the length of the solenoid = 32 cm = 0.32 m
N is the number of turns in the solenoid.
Making N the subject of the formula from the equation above;


Substituting the give values to get N;

The number of turns the solenoid must have is approximately 16,931 turns
Answer:
The value is 
Explanation:
From the question we are told that
The voltage is 
The current is 
Generally the resistance value is mathematically represented as

=> 
=> 
A plateau period refers to a period in life where you are kind of stuck in the middle. There is little growth or decline so you are kind of at a standstill.
