Answer:
Friction
Explanation: is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static friction acts on objects when they are resting on a surface.Nov 3, 2021
The gravity of the Sun keeps the planets in their orbits rotating. The same as the Moon orbits the Earth because of the pull of earth's gravity, the earth orbits the Sun because of the pull of the Sun's gravitational pull.

Answer:
C) 27 A
Explanation:
ΔV = Potential difference across the cylindrical resistor = 10 V
i = current through the resistor = 3 A
R = Resistance of the resistor
Using ohm's law
ΔV = i R
10 = 3 R
R = 3.33 ohm
The resistance of a resistor is inversely related to square of the diameter. So as the diameter is tripled, the resistance becomes 1/9 times
R' = New resistance of the resistor =
i' = new current through the resistor
Using ohm's law
ΔV = i' R'
i' = 27 A
Zoroastrianism affected the way the Persians governed their subjects by allowing the territories under their rule to worship their own religion.
