how many Hydel power system built a river orange​

Answers 2

Because the source of hydroelectric power is water, hydroelectric power plants are usually located on or near a water source. The volume of the water flow and the change in elevation—or fall, and often referred to as head—from one point to another determine the amount of available energy in moving water.

Answer:

so what do we do in this question

Explanation:

question is incomplete

a + b + c = 0and * a ^ 4 + b ^ 4 + c ^ 4 =k(a^ 2 b^ 2 +b^ 2 c^ 2+c^ 2 a ^ 2 ) then k​

Answer:

Given a+b+c=0 and a2+b2+c2=1

a+b+c=0

Squaring on both sides,

a2+b2+c2+2(ab+bc+ca)=0

⇒ab+bc+ca=2−1

Squaring on both sides,

a2b2+b2c2+c2a2+2abc(a+b+c)=41

⇒a2b2+b2c2+c2a2=41

Now, a4+b4+c4=(a2+b2+c2)2−2(a2b2+b2c

The perimeters of a reqular hexagon and a square are equal. The ratio of the area of the square to the are of hexagon is ?​

Answer:

Let the side of the square =a.

Perimeter of the square =4a

Let the side of the hexagon =b

Perimeter of the hexagon =6b

Given, 4a=6b=>a=23b

Area of the square =a2

Area of the hexagon =233b2

Now, Area of square : Area of hexagon = a2:233b2

⇒(23b)2:233b2

⇒49b2:233b2

⇒49:233

⇒3:2
