Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
Answer:
Larger tubines generate more electricity.
Explanation:
Larger blades allow the turbine to capture more of the kinetic energy of the wind by moving more air through the rotors. However, larger blades require more space and higher wind speeds to operate. This distance is necessary to avoid interference between turbines, which decreases the power output.
Answer:
She will have to ride her scooter approximately 10 minutes.
Gravitational field strength (GFS) on earth =10 N/kg
Weight = GFS x mass
W = 10 x 7
W = 70N
70N = 15.74 pounds
