Answer:
The maximum electric field
Explanation:
From the question we are told that
The diameter is
The magnetic field of the cylinder is
The frequency is
The radial distance is
This magnetic field can be represented mathematically as
The initial magnetic field is the average between the variation of the magnetic field which is represented as
Then is the amplitude of the resultant field is mathematically evaluated as
The electric field induced can be represented mathematically as
At maximum electric field
B because it conducts electricity which means it contains a metal hope this helps
From the basic "heat lost by hot object=heat gained by colder object" principle, we have
m1c1ΔT1=m2c2ΔT2
where m1= 1kg
m2=4kg
c1=900J/kg k
c2=4200J/kg k
With this information at hand we have
m1c1(90-T)=m2c2(T-25)
after substituting the given values we can find that
T=28.3^{0}c
