Density is defines as the ratio of mass to volume.
So you measure the mass and volume of a sample, and
divide the mass by the volume, to find the density.
Answer:
0.00851 volts
Explanation:
radius r1= 1.30 cm with ns= 260 turns/cm
radius r2= 4.60 cm and Nc= 23 turns
constant rate from zero to Is= 1.90 A
time interval of 88.0 ms
Area of the solenoid



Mututal Inductance
M=uo*n*N*A1


a)
EMF induced in the outer coil
E=M(dIs/dt)
