Answer:

a sky diver who is midway through his descent to the ground

a roller coaster car halfway down the second hill

a falling raindrop

Explanation:

From the law of conservation of energy, it can neither be created nor destroyed but can be converted from one form to another.

The sum of kinetic energy and potential energy is mechanical energy. A body has potential energy due to its position or configuration and kinetic energy due to its speed.

A body can have both potential energy and kinetic energy.

The correct options are:

  • a sky diver who is midway through his descent to the ground
  • a roller coaster car halfway down the second hill
  • a falling raindrop

A boulder resting on top of a mountain  has just potential energy.

A parked car  also has just potential energy.

Large wind turbines with a power capacity of 8 MW and blade span diameters of over 160 m are available for electric power genera
andriy [413]

Answer:

85413.20177 W

2050.831684248 kWh

184.5748512 dollars

Explanation:

d = Diameter of blade = 100 m

r = Radius = \dfrac{d}{2}=\dfrac{100}{2}=50\ m

\eta = Efficiency = 0.34

\rho = Density of air = 1.25 kg/m³

V = Velocity of wind = 8 m/s

A = Area = \pi r^2

The power of a wind turbine is given by

P=\dfrac{1}{2}\rho AV^3\eta\\\Rightarrow P=\dfrac{1}{2}\times 1.25\times \pi\times 50^2\times 8^3\times 0.34\\\Rightarrow P=854513.20177\ W

The power is 85413.20177 W

Energy is given by

E=Pt\\\Rightarrow E=854513.20177\times 24\\\Rightarrow E=20508316.84248\ Wh\\\Rightarrow E=2050.831684248\ kWh

The energy is 2050.831684248 kWh

The revenue is given by

0.09\times 2050.831684248=184.5748512\$

The revenue generated is 184.5748512 dollars
