Answer:

7.5 MW

Step-by-step explanation:

The power generated from a falling water is a function of its height and volume. The power generated an be calculated using the formula:

Power (P) = Density(ρ) * volume flow rate(Q) * acceleration due to gravity(g) * height(h)

P = ρQgh

But Qh = Velocity(v) * volume(V).

Hence power = ρvgV

Given that ρ of water = 1000 kg/m³, v = 75 m/s, V = 10 m³, g = 10 m/s². Substituting:

P = ρvgV = 1000 * 75 * 10 * 10 = 7500000 W

P = 7.5 MW

The expression can represent the value of x in terms of R, m, n and k after rearranging.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The expression is:

\rm R = 4m\sqrt{\dfrac{xn}{k^3}}

Square both side:

\rm R^2 = 16m^2{\dfrac{xn}{k^3}}

16m² x n = R²k³

x = (R²k³)/(16m²n)

The above expression represents the value of x in terms of R, m, n and k.

Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.

Name the theorem or postulate that can be used to prove that these triangles are similar
Musya8 [376]

Answer:SAS

Step-by-step explanation:Similar triangles are easy to identify because you can apply three theorems specific to triangles. These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are foolproof methods for determining similarity in triangles.
