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

Answer:
Car A is 1.8-1.2= 0.6 times faster than car B
So the distance between them is changing 0.6 times faster.
Explanation:
Car A is traveling north at 90km/hr and 0.3 km away from intersection point.
Car b is traveling west at 80km/hr and 0.4 km away from the intersection point.
The time it will take to get to intersection point by those two cars is how fast it is changing.
For car A
Time = distance/speed
Time = 0.3/90
Time = 3.333*10^-3
Time = 3.333*10^-3 hrs
Converting to seconds
(3.333*10^-3)*360= 1.199998
Approximately 1.2 seconds
For car B
Time = distance/time
Time= 0.4/80
Time = 5*10^-3
Time= 5*10^-3 hrs
Converting to seconds
(5*10^-3)*360= 1.8 seconds
Comparing the two times,
Car A is 1.8-1.2= 0.6 times faster than car B

conductivity is when an object can pass electricity flow through itself
Explanation:
ex: metal
Answer:
2.55 Hz
Explanation:
frequency = Speed of wave / wavelength
= 21.2 / 8.3
= 2.55 Hz
