Answer:</h2>
(a) 10.00V
(b) 0.5V
<h2>
Explanation:</h2>
(a) The power(P) supplied by a resistor of resistance (R) when a voltage(V) is passed across is given by;
P = V² / R ------------------(i)
From the question;
P = 5.00W
R = 20.00Ω
Substitute these values into equation (i) as follows;
5.00 = V² / 20.00
V² = 5.00 x 20.00
V² = 100.00
V = 
Solve for V;
V = 10.00V
Therefore, the maximum voltage that can be applied without harming the resistor is 10.00V
(b) By Ohm's law the current (I) flowing through a resistor of resistance (R) when a voltage (V) is applied is given by;
V = I x R
=> I = V / R ----------------(ii)
Substitute the values of V and R into equation (ii) as follows;
I = 10.00 / 20.00
I = 0.5A
Therefore, the current through the resistor is 0.5A
The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.

Resistance</h3>
Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:
Given that R₂ = 469 ohm, hence:
But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
![R_1=\rho \frac{l_1}{A_1}=\rho *\frac{6l_2}{[\pi (1/5)r_2]^2} =150 * \rho \frac{l_2}{[\pi r_2]^2}=30*469=70350\ ohm](https://tex.z-dn.net/?f=R_1%3D%5Crho%20%5Cfrac%7Bl_1%7D%7BA_1%7D%3D%5Crho%20%2A%5Cfrac%7B6l_2%7D%7B%5B%5Cpi%20%281%2F5%29r_2%5D%5E2%7D%20%3D150%20%2A%20%5Crho%20%5Cfrac%7Bl_2%7D%7B%5B%5Cpi%20r_2%5D%5E2%7D%3D30%2A469%3D70350%5C%20ohm)

Bio-gas is the naturally produced fossil fuel, a by-product when bacteria decompose organic material under anaerobic conditions.
<h3><u>Explanation:</u></h3>
Organic matter particularly waste material is broken down by bacteria through fermentation in an environmental condition without any presence of oxygen. This process of decomposition leads to formation of bio-gas with "carbon dioxide and methane" in a 2:3 ratio.
The above biological process is termed as bio-digestion or anaerobic digestion. Methane is flammable and thus bio-gas can be used as "energy source", a waste-to-energy transformation. The remaining decomposed matter is ideal as manure for plants due to its rich nutrient level.
