Answer:
1.18
Explanation:
The flow rate of blood is proportional to the fourth power of its radius as given the Poiseuille's law.
The law is :
It is given here that the flood flow rate is been reduced to half its normal value. Therefore,
So, for the radius and , the ratios of their flow rates are :
It is given that the flow rate is reduced to half. So we have,
or
So the radius changes by a factor of 1.18

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,
.
