Alternating current (AC) flows half the time in one direction and half the time in the other, changing its polarity 120 times per second with 60-hertz current.
Answer:
At Saturn's center is a dense core of metals like iron and nickel surrounded by rocky material and other compounds solidified by the intense pressure and heat. It is enveloped by liquid metallic hydrogen inside a layer of liquid hydrogen—similar to Jupiter's core but considerably smaller

Answer:
- Peat soil
- Loamy soil
- Clay soil
Explanation:
Peat soil is dark, highly decomposed organic matter found in soil.
Loamy soil is a mixture of materials that holds moisture and drains well and also contains coarse grains and allows water to drain quickly.
Clay soil contains medium grains and retains water. Also it contains fine grains and has little space for water.
To develop this problem it is necessary to apply the concepts related to a magnetic field in spheres.
By definition we know that the magnetic field in a sphere can be described as

Where,
a = Radius
z = Distance to the magnetic field
I = Current
Permeability constant in free space
Our values are given as
diameter of the sphere then,

Thus z = a



Re-arrange to find I,



Therefore the current at the pole of this sphere is
