There are actually two types of fossil fuels that when burned are the least polluting. First, you have natural gas, and secondly, coal. These two are the fossil fuels that pollute the least when burned.

AuthenticD3mon and I talked it over and agreed that
natural gas is the least polluting fossil fuel.

Basile [38]

The electrostatic energy stored in a capacitor with capacitance $C_0$ , with a voltage difference V applied to it, and without dielectric, is given by
$U_0 = \frac{1}{2} C_0 V^2$
Now let's assume we fill the space between the two plates of the capacitor with a dielectric with constant k. The new capacitance of the capacitor is
$C_k = k C_0$
So, the energy stored now is
$U_k = \frac{1}{2}C_k V^2= \frac{1}{2}kC_0 V^2$

Therefore, the ratio between the energies stored in the capacitor before and after the introduction of the dielectric is
$\frac{U_k}{U_0}= \frac{ \frac{1}{2}kC_0 V^2 }{ \frac{1}{2} C_0 V^2}= k$

3. If a pipe with flowing water has a cross-sectional area nine times greater at point 2 than at point 1, what would be the rela

shusha [124]

Answer:

The velocity of the flow at point 1 is nine times greater than the velocity at point 2.

Explanation:

We know that the same volume of water entering through point 1 must exit through point 2.

The volume of water per unit of time or the volumetric flow is defined by:

$V_{flow}=v*A\\ where:\\V_{flow}= flow [m^3/s]\\v=velocity[m/s]\\A=area [m^2]$
