Answer:
It gives our light which we need for probably everything.
Explanation:
If you have 12 atoms of hydrogen before a chemical reaction, the number of hydrogen atoms that will be present after the chemical reaction is 12 atoms.
The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed before and after any chemical reaction.
According to the Law of Conservation of Mass (LOCOM), a balanced chemical equation requires that the number of atoms on the reactant side must be equal to the number of atoms on the product side of any chemical reaction.
In this context, a chemical reaction having 12 atoms of hydrogen as reactants at the beginning, should also produce a total of 12 atoms of hydrogen as products at the end of the chemical reaction.
The answer is 8 because multiplying 7 and 8 is 56
Answer:
Resistance of the circuit is 820 Ω
Explanation:
Given:
Two galvanometer resistance are given along with its voltages.
Let the resistance is "R" and the values of voltages be 'V' and 'V1' along with 'G' and 'G1'.
⇒ 
⇒ 
Concept to be used:
Conversion of galvanometer into voltmeter.
Let 
be the resistance of the galvanometer and 
the maximum deflection in the galvanometer.
To measure maximum voltage resistance 
is connected in series .
So,
⇒ 
We have to find the value of we know that in series circuit current are same.
For 
For 
⇒ 
equation (i) ⇒ 
equation (ii)
Equating both the above equations:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
⇒ 
The coil resistance of the circuit is 820 Ω .
