Water flows over a section of Niagara Falls at rate of 1.1×10^6 kg/s and falls 49.4 m. How much power is generated by the fallin
DerKrebs [107]

Answer:

<em>The power generated is =  5.33×10⁸ Watt. </em>

Explanation:

Power: Power can be defined as the time rate of doing work. The S.I unit of power is <em>Watt(W).</em>

<em>Mathematically,</em>

<em>Power (P) = Work done/time or Energy/time</em>

P = mgh/t............................... Equation 1

P = δgh............................. Equation 2

Where δ = fall rate, g = acceleration due to gravity, h = height.

<em>Given: </em>δ = 1.1×10⁶ kg/s, h = 49.4 m g = 9.81 m/s²

Substituting these values into equation 2

P = 1.1×10⁶×49.4×9.81

P = 533.08×10⁶

<em>P = 5.33×10⁸ Watt.</em>

<em>Thus the power generated is =  5.33×10⁸ Watt. </em>

If ice has a density of.92g/cm, what is the volume of 1.8 kilograms of ice?
steposvetlana [31]
Given:
Density = .92 g / cm³
Volume = 1.8 kg
            = (1.8 * 1000) grams
            = 1800 grams
Now,
Density (d) = \frac{Mass (m)}{volume(v)}

volume (v)= \frac{mass(m)}{density(d)}

volume (v)= \frac{1800}{.92}

volume (v)= 1956.521739

volume (v)= 1956.5~ cm^{3}

So, the volume of 1.8 kg of ice is 1956.5 cm³
