I believe your answer is correct, because 8.7*10^-7 is equal to 0.00000085347.
Hope you do well!
Vas happenin!!!
Hope your day is good
I would say observational tool
Hope this helps

Answer:
Approximately 18 volts when the magnetic field strength increases from to at a constant rate.
Explanation:
By the Faraday's Law of Induction, the EMF that a changing magnetic flux induces in a coil is:
,
where
- is the number of turns in the coil, and
- is the rate of change in magnetic flux through this coil.
However, for a coil the magnetic flux is equal to
,
where
- is the magnetic field strength at the coil, and
- is the area of the coil perpendicular to the magnetic field.
For this coil, the magnetic field is perpendicular to coil, so and . The area of this circular coil is equal to .
doesn't change, so the rate of change in the magnetic flux through the coil depends only on the rate of change in the magnetic field strength . The size of the magnetic field at the instant that will not matter as long as the rate of change in is constant.
.
As a result,
.
A material that resists the flow of electrons is called an insulator.
