In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the t
ozzi

Answer:

C: 31 m/s

Step-by-step explanation:

It falls from a dam.

Thus;

Initial velocity; u = 0 m/s

Height; h = 49 m

Acceleration due to gravity is 9.8 m/s²

To solve for the final velocity this, we will use Newton's third equation of motion;

v² = u² + 2gh

v² = 0² + 2(9.8 × 49)

v = √960.5

v ≈ 31 m/s

The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

0.1x + 0.25y = 19.9 and

x + y = 100

Let x = number of dimes

y = number of quarters

After solving the above system of equations by substitution method.

\rm \dfrac{398-5y}{2}+y=100

y = 66

\rm x=\dfrac{398-5\cdot \:66}{2}

x = 34

Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
