Answer:
The current in the wire = 39.53 A.
Explanation:
The given cross -sectional area of the wire = 1.35 .
The number of electrons flowing in the wire at any point is
= 5.41 electrons.
The charge of an electron is known to be =
The electronics flow across the wire for a time of, t = 2.19 seconds.
The current in the wire = (number of electrons) ×
= 5.41 ×
= 39.53 A.
The formula for current is actually, i = .
The (number of electrons )×(charge of an electron) will equal the total charge flowing through the wire in the given time = 2.19 seconds.
The current in the wire = 39.53 A.
Answer:
Unknown
Explanation:
Because we cannot observe space beyond the edge of the observable universe, it is unknown whether the size of the Universe in its totality is finite or infinite.
Answer:
Rusting!
Explanation:
Rusting is a chemical reaction because it is the process of oxidation of a metal.
Gravity is a conservative force.
That means that when you move around in a gravitational field,
the amount of energy you need in order to get someplace
depends only on where you start and where you finish, and
it's not affected by the route you take to get there.
Friction ... as an example ... is not like that. If friction is present and
you wander around on the way from 'A' to 'B', taking a longer route,
then you'll need more energy than you would need for a more direct,
shorter route.
