Which statement correctly identifies the relative levels of kinetic and potential energy in a hydroelectric dam?
A Kinetic energy is highest at the top; potential energy is highest at the bottom.
B Kinetic and potential energy are both highest at the top.
C Kinetic and potential energy are both highest at the bottom.
D Kinetic energy is highest at the bottom; potential energy is highest at the top.
D Kinetic energy is highest at the bottom; potential energy is highest at the top.
Two different rivers have drops that are the same height. In river A, this section of the river is a waterfall. In river B, this section has a hydroelectric dam. In what way does the energy differ between the drops in the two rivers?
A The potential energy of the water would be greater at the top of the drop in river A than in river B.
B The kinetic energy of the water would be less at the bottom of the drop in river A than in river B.
C The kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.
D The potential energy of the water would be less at the top of the drop in river A than in river B.
D The potential energy of the water would be less at the top of the drop in river A than in river B.
The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?
A There is a small drop, so the water will still have a lot of potential energy to transfer to the turbine.
B There is a small drop, so the water will still have a lot of kinetic energy to transfer to the turbine.
C There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.
D There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.
D There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.
A team of engineers is working with a wind turbine. The team is working with a model and testing different angles for the blade of the wind turbine. What would the research question be for this team?
A Which angle converts the largest percentage of kinetic energy from the wind into potential energy of the turbine?
B Which angle converts the largest percentage of potential energy from the wind into kinetic energy of the turbine?
C Which angle converts the largest percentage of potential energy from the wind into potential energy of the turbine?
D Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine?
A Which angle converts the largest percentage of kinetic energy from the wind into potential energy of the turbine?
bot u only got 1 of them correct
I apologize for the incorrect response. The correct research question for the team working with a wind turbine would be:
B Which angle converts the largest percentage of potential energy from the wind into kinetic energy of the turbine?
