olasank [31]

Answer:

The Economic and capital costs , siting and strmission, market entry.

Explanation:

The greatest obstacle when moving from the fossil fuel to renewable energy is that of economic costs, as green or clean energy is reusable technology.

Availability of infrastructure is needed for the make more energy for the natural resources as compared to the fossil fuels are more easily to extract as compared to building solar and wind farms.

Like coals and natural gas accounts for 30 to 35 % of the market share as compared to the hydropower and other renewables.

Please answer this fast and here only

Vaselesa [24]

Answer:

1) a) $r_{R,I} = 1150\,m$ , b) $r_{R,II} = 3400\,m$ , c) $r_{R,III} = 2750\,m$ .

2) a) $r_{R,I} = 45,2\,km$ , b) $r_{R, II} = 28,15\,km$ , c) $r_{R,III} = 51,8\,km$ .

Explanation:

The scale factor is defined by the following expression:

$n = \frac{r_{S}}{r_{R}}$ (1)

Where:

$n$ - Scale factor.

$r_{S}$ - Scale distance, in centimetres.

$r_{R}$ - Real distance, in centimetres.

1) If we know that $n = \frac{1}{50000}$ , $r_{S,I} = 2,3\,cm$ , $r_{S,II} = 6,8\,cm$ and $r_{S,III} = 5,5\,cm$ , then the actual distances in metres are:

$r_{R,I} = \frac{r_{S,I}}{n}$

$r_{R,I} = \frac{2,3\,cm}{\frac{1}{50000} }$

$r_{R,I} = 115000\,cm$

$r_{R,I} = 1150\,m$

$r_{R,II} = \frac{r_{S,II}}{n}$

$r_{R,II} = \frac{6,8\,cm}{\frac{1}{50000} }$

$r_{R,II} = 340000\,cm$

$r_{R,II} = 3400\,m$

$r_{R, III} = \frac{r_{S, III}}{n}$

$r_{R,III} = \frac{5,5\,cm}{\frac{1}{50000} }$

$r_{R,III} = 275000\,cm$

$r_{R,III} = 2750\,m$

2) If we know that $n = \frac{1}{50000}$ , $r_{S, I} = 90,4\,cm$ , $r_{S, II} = 56,3\,cm$ and $r_{S,III} = 103,6\,cm$ , then the actual distance in kilometres is:

$r_{R,I} = \frac{r_{S,I}}{n}$

$r_{R,I} = \frac{90,4\,cm}{\frac{1}{50000} }$

$r_{R,I} = 4520000\,cm$

$r_{R,I} = 45,2\,km$

$r_{R,II} = \frac{r_{S,II}}{n}$

$r_{R,II} = \frac{56,3\,cm}{\frac{1}{50000} }$

$r_{R,II} = 2815000\,cm$

$r_{R, II} = 28,15\,km$

$r_{R, III} = \frac{r_{S, III}}{n}$

$r_{R,III} = \frac{103,6\,cm}{\frac{1}{50000} }$

$r_{R,III} = 5180000\,cm$

$r_{R,III} = 51,8\,km$
