Answer:
the missing angle is 5m
Step-by-step explanation:
Angle of elevation would be 66 degrees
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
-1/5 (x - 4) = -2
(-1/5)x + (4/5) = -2
-2 can be turned into -10/5
(-1/5)x = (-10/5) - (4/5)
(-1/5)x = -14/5
multiply by -5 on both sides
x = 14
hope this helps :)
