Correct question is;
Resistance of a given wire is obtained by measuring the current flowing in it and the voltage difference applied across it. If the percentage errors in the measurement of the current and the voltage difference are 3% each, then error in the value of resistance of the wire is?
Answer:
6%
Explanation:
From ohms law, we know that;
R = V/I
Where;
R is resistance
V is voltage
I is current
Now, the percentage error in the resistance is given by the formula;
ΔR/R = ΔV/V+ ΔI/I
We are told that the current and the voltage difference have a percentage error of 3% each. Thus;
ΔR/R = 3% + 3% = 6%
Answer:
2) MgO ---→ Mg + O2
Explanation:
Chemical decomposition is defined as the breakdown or breaking of a single molecule or entity into two or more smaller fragments.
Chemical decomposition is usually regarded as the exact opposite of chemical synthesis. In most cases, the chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.
Answer:
i think its a mixture because it has different things mixed with it like chocolate, marshmallows and other stuff
