Water flows on the Amazon river near the cachoeira de Santuario waterfalls at a velocity 75 meters per second. If a low height r
zysi [14]

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

Need help on 13 and 14

13. Supplementary angles are two angles that add up to 180 degrees.

3x + x = 180

Combine like terms:
4x = 180

4x divided by 4 = x

180 divided by 4 = 45

x = 45

Equation:
3(45) + 45 = 180

135 + 45 = 180 (TRUE STATEMENT)

Angle A = 135 degrees
Angle B = 45 degrees

This is correct as 135 + 45 adds up to 180 (making it a supplementary angle) AND 135 is 3 times bigger than 45 so it fits the answer’s standard.

Ima do number 14 in the comments as I don’t want to take too long to show number 13.

What is the unit rate of 12 gallons of water in 5 mins
klasskru [66]
(12 gallons)/(5 minutes<span>) = (2.4 </span>gallons<span>)/(1 minute)
So it'd be 2.4 gallons a minute.

Have a nice day! :D</span>
