This process is called a quantization error. It is the difference between the analog signal and digital values.
<h3>What is a quantization error?</h3>
Quantization error refers to the difference between analog signals and their closest digital values during the process of sampling.
This process (quantization error) involves an A/D converter, i.e., an analog to a digital converter (ADC).
The A/D converter is a type of converter that acts by capturing analog signals at given fixed time intervals.

Given:
The mass of the copper cylinder is: m = 76.8 g = 0.0768 kg
The change in the temperature is: T = 86.5 deg C - 19.5 deg C = 67 deg C
The specific heat is: c = 0.092 cal/g.C
To find:
Heat energy needed to heat the copper cylinder.
Explanation:
The specific heat is defined as the amount of heat energy needed to raise the temperature of a substance by one degree celcius.
The expression relating heat Q, mass m, specific heat c and temperature difference T is:
Substitute the values in the above equation, we get:
Final answer:
473.40 calories of heat is required to heat the copper cylinder.
Explanation :
Corrosion is the process of conversion of metal into its oxides, hydroxides and sulfides.
Rusting of iron is the process of corrosion in metals. Iron objects react with oxygen in the air and turned reddish. This reddish covering is Rust.
where, is iron
is oxygen present in atmosphere
and is rust or Ferric oxide.
In the given equation, and both are reactants and is a product.
Answer:
Explanation:
Some data in the problem are missing.
Missing values:
Radius of the cylinder: 13 cm
Height of the cylinder: 4 cm
The volume of a cylinder is given by
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem, we have:
r = 13 cm (radius)
h = 4 cm (height)
Therefore, the volume of the cylinder is:
Answer:Resistivity of the wire is 7.065 × 10^-8 Ω m.
