1) Which statement correctly identifies the relative levels of kinetic and potential energy in a hydroelectric dam?(1 point)
Kinetic and potential energy are both highest at the top.
Kinetic energy is highest at the top; potential energy is highest at the bottom.
Kinetic energy is highest at the bottom; potential energy is highest at the top.***
Kinetic and potential energy are both highest at the bottom.
2)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?(1 point)
The kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.
The potential energy of the water would be less at the top of the drop in river A than in river B.
The kinetic energy of the water would be less at the bottom of the drop in river A than in river B.***
The potential energy of the water would be greater at the top of the drop in river A than in river B.
3)The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?
(1 point)
There is a small drop, so the water will still have a lot of kinetic energy to transfer to the turbine.
There is a small drop, so the water will still have a lot of potential energy to transfer to the turbine.
There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.***
There is a large drop, so the water will have a lot of potential energy to transfer to the turbine
4)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?(1 point)
Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine?***
Which angle converts the largest percentage of potential energy from the wind into kinetic energy of the turbine?
Which angle converts the largest percentage of potential energy from the wind into potential energy of the turbine?
Which angle converts the largest percentage of kinetic energy from the wind into potential energy of the turbine?
Can somebody check my answers please?
1) Kinetic energy is highest at the bottom; potential energy is highest at the top.
2) The kinetic energy of the water would be greater at the bottom of the river in river A than in river B.
3) There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.
4) Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy from the turbine?
Hope this helps :)
here are the correct answers in word form.
1) Kinetic energy is highest at the bottom; potential energy is highest at the top.
2)The kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.
3) there is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.
4)Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine?
Teehee is 100% correct. Thank you!
GUYS LISTEN stop submitting your answers in letter form the'll all be wrong because for tests and quizzes is randomizes the order of the answers
Teehee is correct!! 100% Thank you!!
Here are the answers to the 8th grade Using Potential and Kinetic Energy quick check'
1). Kinetic energy is highest at the bottom; potential energy is highest at the top.
2). The kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.
3). There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.
4). Which angle converts the largest percentage of kinetic energy from the wind into kinetic energy of the turbine?
I promise these are right. If they aren't, I will venmo you $100. Keep in mind this is for the EIGHTH GRADE USING POTENTIAL AND KINETIC ENERGY QUICK CHECK!! Only eighth grade, I ain't venmoing some 6th grader $100 just because they couldn't read what grade it is. Have a great day y'all!
