c. Wind power can turn turbines to generate electrical power.

Explanation:

The correct statement of all is that wind power can turn turbines to generate electrical power.

This is simply the way wind energy from waves are usually harnessed to produce electricity.

  • When a metallic conductor passes in between magnetic fields, it induces and generates electricity as it turns.
  • This is how electricity generating plants are fashioned.
  • Geothermal energy is not generated from moving water. It is produced from heat within the earth brought to the surface. Power from moving water is hydroelectric power.
  • Oil is a non-renewable resource
  • Propane is a non-renewable resource

What is the maximum speed when the conditions are mass =450 kg, initial height= 30 m, and the roller coaster is initially at res
Zarrin [17]

Answer:

B. 24.2 m/s

Explanation:

Given;

mass of the roller coaster, m = 450 kg

height of the roller coaster, h = 30 m

The maximum potential energy of the roller coaster  due to its height is given by;

P.E_{max} = mgh\\\\PE_{max} = 450 *9.8*30\\\\PE_{max} = 132,300 \ J

P.E_{max} = K.E_{max} \ (law \ of \ conservation\ of \ energy)

K.E_{max} = \frac{1}{2}mv_{max}^2\\\\ v_{max}^2 = \frac{2K.E_{max}}{m}\\\\ v_{max}^2 = \frac{2*132300}{450}\\\\ v_{max}^2 =588\\\\v_{max} = \sqrt{588}\\\\  v_{max} = 24.2 \ m/s

Therefore, the maximum speed of the roller coaster is 24.2 m/s.

Which two possible explanations does the video give for why white light changes into colored light? Color is an impurity added t
Alex777 [14]

Answer:

White light contains seven colors, which are separated by the prism.

White light reacts with chemicals in the air to produce seven colors.

Explanation:

It was first observed by Sir Issac Newton, that when white light is passed through a prism, an elongated, coloured patch of light is obtained on a screen placed behind the prism. The seven colours obtained constitute the spectrum of white light.

In nature, white light is separated into its constituent wavelengths when white light interacts with substances in the atmosphere.
