Answer:

d. The earth rotates around the sun

Explanation:

  • Nicolas Copernicus is considered the first person to give the theory of heliocentric, or Sun-centered system of our planetary system.
  • In the heliocentric system, it is considered that the sun is stationary and the earth revolves around the sun.
  • He stated that the sun is at the center of the universe and the earth spins on its axis once daily and revolves around the sun in one year.
  • And today we know it is correct that earth rotates on its own axis and also revolves around the sun.

A silver wire with resistivity 1.59 × 10-8 Ω-m carries a current density of 4.0 A/mm2, What is the magnitude of the electric fie
Nat2105 [25]

Answer:

Electric field, E = 0.064 V/m

Explanation:

It is given that,

Resistivity of silver wire, \rho=1.59\times 10^{-8}\ \Omega-m

Current density of the wire, J=4\ A/mm^2=4\times 10^6\ A/m^2

We need to find the magnitude of the electric field inside the wire. The relationship between electric field and the current density is given by :

E=J\times \rho

E=4\times 10^6\times 1.59\times 10^{-8}

E = 0.0636 V/m

or

E = 0.064 V/m

So, the magnitude of electric field inside the wire is 0.064 V/m. Hence, this is the required solution.

steposvetlana [31]
D. All of the above. When a wire loop is moved or rotated in a magnetic field, there is a change in magnetic flux which produces emf in wire loop and hence electric current is produced.
