<span>It is the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
Every planet has their own corresponding escape velocities. Example - Earth has escape velocity of 11.2 Km/s. It means, if you want to leave the Earth's gravitational field then it's the lowest speed which you need to acquire otherwise you wouldn't do that!
Hope this helps!</span>
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.
<h3>What is the Avogadro’s number?</h3>
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.
The scientist Josef Loschmidt strengthened the Avogadro’s number by obtaining the number of particles in one cubic centimeter of gas under standard conditions.

Answer:20ohms
Explanation:
According to ohms law, the current passing through a metallic conductor is directly proportional to the potential difference across its ends. Mathematically,
V = IR where;
V is the potential difference
I is the current
R is the resistance
Given current I that the iron carries = 6.0A
Voltage source (the Emf) = 1.2×10²V
resistance R = V/I
R = 120/6
R = 20ohms
Therefore the resistance of the steam iron is 20ohms
