Answer:
2.8512*10^8 inches
Explanation:
Seeing as the ratio for miles to inches is 1 mile = 63360 inches, set up an equation. 1 mile / 63360 inches = 4500 miles / x inches. Cross multiply and simplify to 2.8512*10^8 inches. Hope this helps! :)

Answer:
The magnitude of the average induced emf in the loop is 0.1 volts.
Explanation:
let Ф be the flux in the loop, B be the magnetic field and A be the area of the loop.
the induced emf in the loop is given by:
ε = - dФ/dt
= - d(B×A)/dt
= - A×d(B)/dt
= - π×r^2×d(B)/dt
= - π×(0.40)^2×(0.20 - (-0.30))/(2.5 - 0)
= 0.1 volt
Therefore, the magnitude of the average induced emf in the loop is 0.1 volts.
By definition,
density = mass/volume
The mass is 82 g
The volume is 14 cm³
Therefore
density = (82 g)/(14 cm³) = 5.857 g/cm³
In SI units, density = 5857 kg/m³
Answer: 5.857 g/cm³
