The total consumption of electrical energy in the United States is about 1.0 1019 joules per year.

dexar [7]

Answer:

a) 316880878140.2895 Joules

b) 1056.26 Joules

c) 372.80103310622 km²

Explanation:

Energy consumption

$E=\frac{P}{t}\\\Rightarrow E=\frac{1\times 10^{19}}{365.25\times 24\times 60\times 60}\\\Rightarrow E=316880878140.2895\ W$

Average rate of electrical energy consumption is 316880878140.2895 Joules

Total population = 300 million

$E=\frac{316880878140.2895}{300\times 10^6}\\\Rightarrow E=1056.26\ J$

Each person consumes 1056.26 Joules.

Efficiency = 0.85

Power from Sun

$0.85\times 1000=850\ W/m^2$

Area

$\frac{316880878140.2895}{850}=372801033.10622\ m^2$

Converting to km²

$372801033.10622=\frac{372801033.10622}{1000\times 1000}=372.80103310622\ km^2$

Area required to collect the electrical energy used in the United States is 372.80103310622 km²

Annie is considering two different coach journeys from Bristol to Birmingham.

Alexeev081 [22]

The average speed in the first case is 19.86 m/s and the average speed in the second case is 13.67 m/s.

The formula of average speed is

average speed = total distance / total time

In first case

total distance is 143 km which is also 143000 m

and total time is 2 hours which is also 7200 seconds

so average speed = ( 143000 / 7200 ) m/s

average speed = 19.86 m/s

In second case

total distance is 160 km which is also 160000 m

and total time is 3 hours and 15 minutes which is also 11700 seconds

so average speed = ( 160000 / 11700 ) m/s

average speed = 13.67 m/s

So to conclude with we have find the the average speed in both cases by dividing total distance by total time and in first case we have got our answer as 19.86 m/s and in second case we have got 13.67 m/s.
