Answer:
C) Valence electrons.
Explanation:
When a chemical bond is formed it is the electrons that are shared and it is they that hold the two atoms together due to the coulomb forces between the positive nuclei and the valence electrons. To put in in another way, both nuclei of the bond want the electrons, but neither can get them, regardless, they hold on to them, and this is what makes a chemical bond.
The time required (in s) for the magnetic field to decrease to zero from its maximum value is 1.2 x 10⁻⁶ s.
<h3>
Faraday's law of electromagnetic induction</h3>
Faraday's first law of electromagnetic induction states, “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced.
emf = NdФ/dt
emf = NBA/t
where;
- N is number of turns of the coil
- A is area of the coil
- B is magnetic field
- t is time
The time required (in s) for the magnetic field to decrease to zero from its maximum value is calculated as follows;
t = NBA/emf
t = (16 x 1.1 x 10⁻³ x 3.75 x 10⁻⁴) / (5.5)
t = 1.2 x 10⁻⁶ s
Thus, the time required (in s) for the magnetic field to decrease to zero from its maximum value is 1.2 x 10⁻⁶ s.

Not close because it’ll blow up if too close.
Answer:
Explanation:
is the angle between the velocity and the magnetic field. So, the magnetic force on the proton is:
A charged particle describes a semicircle in a uniform magnetic field. Therefore, applying Newton's second law to uniform circular motion:
is the centripetal force and is defined as:
Here 
is the proton's speed and 
is the radius of the circular motion. Replacing this in (1) and solving for r:
Recall that 1 J is equal to 
, so:
We can calculate from the kinetic energy of the proton:
Finally, we calculate the radius of the proton path:
