Answer:
answer down below
Explanation:
it has similar mass but the white dwarf is much denser
Answer:
The conduction path or simply the wires connected between different components in a circuit.
Explanation:
The wire makes up the path for the electricity to flow and most of the electricity flows through this. It is like a road connecting two house or buildings in a town and the traffic of vehicles is the electricity (current).
Answer:
The magnitude of the current flowing through the wire is 7 A.
Explanation:
Given that,
Radius of the circular loop, r = 4 mm = 0.004 m
Magnetic field at the centre of the loop, B = 1.1 mT
We need to find the magnitude of the current flowing through the wire. The magnetic field at the center of the loop is given by the formula as follows :
So, the magnitude of the current flowing through the wire is 7 A.
publish a book in which he explained his heliocentric theory.
Explanation:
The heliocentric theory is the one according which the Sun is in the center of our Solar Sistem and the planets go around it.
Previously to this theory (before Copernicus) the prevalent theory was geocentrism accordind which it was the earth who stood in the center and all the other celestial bodies went around it.
