<h2>Answer: True </h2><h2 />
Faraday's Law (also known as Faraday's Law of Electromagnetic Induction) was formulated from the experiments made by him and states that:
<em>The voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as edge changes in time
</em>
<em></em>
where:
is the Electric Field
is the infinitesimal element of the C contour
is the magnetic field density
is an arbitrary surface, whose edge is C
The negative sign indicates the direction of the induced current and refers to the opposition between the fields induced by the magnetic flux and the electromotive force. In addition, its consequences are also expressed in the Lenz law, which states that the induced electricity will be in a direction such that it opposes the variation of the magnetic flux that produced it as a consequence of the principle of conservation of energy.
Therefore:
<h2>If he minus sign were not in Faraday's law it would lead to a violation of the law of conservation of energy

Answer:
The balanced equations are as follows:
✅ FeCl₃ + 3NH₄OH ➡ Fe(OH)₃ + 3NH₄Cl
✅ CH₄ + O₂ ➡ CO₂ + 2H₂O
✅ 2Fe + 3H₂SO₂ ➡ Fe₂(SO₂)₃ + 3H₂
✅ PCl₅ + 4H₂O ➡ 5HCl + H₃PO₄
Explanation:
In the equation, FeCl₃ + 3NH₄OH ➡ Fe(OH)₃ + 3NH₄Cl, Charlie will adjust the number of atoms in NH₄OH in order for NH₄, Cl and OH to balance in the product side. 3 was placed in front of NH₄OH and NH₄Cl in order the balance it.
In the equation, CH₄ + O₂ ➡ CO₂ + 2H₂O, Charlie will adjust the number of atoms in H₂O. 2 was placed in front of H₂O in order to balance the atoms in the reactant and product sides.
In the equation, 2Fe + 3H₂SO₂ ➡ Fe₂(SO₂)₃ + 3H₂, Charlie will adjust the number of atoms in the reactant side in order for the product side to be balanced.
In the equation, PCl₅ + 4H₂O ➡ 5HCl + H₃PO₄, Charlie will adjust the number of atoms in H₂O and HCl for the equation to be balanced. 4 and 5 were placed in front of H₂O and HCl respectively in order for the equation to be balanced.
In chemical equations, it is required that the number of atoms of each element found in the reactants must be equal to the number of atoms of each element found in the products. This makes the chemical equation balanced.
Answer:
16 m / s
Explanation:
Average kinetic energy of one mole of a gas is given by the expression
K.E = 3 / 2 R T { T is absolute temperature of the gas }
Putting the values , we get
4070 = 3 / 2 X 8.312 X T
T = 326.35 K
Under similar condition temperature of oxygen will also be same . So temperature of oxygen gas will be 326.35 K.
Now ,RMS value of a gas =
T is absolute temperature of gas and M is molecular mass.
Molecular mass of oxygen is 32 gm . T is 326.35
RMS speed =
= 16 m / s . approx.
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
