Answer:
Explanation:
a.
Given the permittivity constant to be 
,The capacitance of a 
of length, 
is given by the equation:
where 
is the radius of the outer cylinder and 
the radius of the inner cylinder.
The values are given as:
Substitute in our capacitance equation:
Hence the capacitance is 
b. The charge on the capacitance is related to the potential difference across it. The potential difference is expressed using the equation:
,
From a above, we already have our capacitance value,
We substitute 
in the pd equation:
Hence, the applied potential difference is 2.7344V
Your answer would be D, Hydroelectric power
From the calculations, the final momentum of B is 8.16 m/s
<h3>What is conservation of linear momentum?</h3>
According to the principle of the conservation of linear momentum, the momentum before collision is equal to the total momentum after collision.
This implies that;
MaUa + MbUb = MaVa + MaVa
Substituting values;
(0.08 kg * 0.5 m/s) + (0.05 kg * 0 m/s) = (0.08 kg * −0.1 m/s) + (0.05 kg * v)
0.4 = -0.008 + 0.05v
v = 8.16 m/s

<span>A substance that accelerates the rate of chemical reaction is called a catalyst. It serves as an alternative pathway for the reaction product. The increase of rate of chemical reaction is because catalyst has low activiation energy than the original pathway. The low activation energy will increase the amount of molecules that can benefit in the energy created by the catalyst.</span>
