1) Which statement correctly identifies the relative levels of kinetic and potential energy in a hydroelectric dam? (1 point) Kinetic energy and potential energy are both highest at the top.
Kinetic energy is highest at the top; the potential energy is highest at the bottom.
Kinetic energy is highest at the bottom; the potential energy is highest at the top.***
Kinetic and potential energy are both highest at the bottom.
2) Two different rivers have height differences of the same height. In River A, this section of the river is a waterfall. In River B, this section has a hydroelectric dam. How does the energy differ between the drops of the two rivers? (1 mark)
The kinetic energy of water would be greater at the bottom of the drop in river A than in river B.
The potential energy of 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 waterfall in River A than in River B.***
The potential energy of water would be greater at the top of the drop in river A than in river B.
3) The turbines are visible inside this hydroelectric dam. Why are they located at this particular height?
(1 mark)
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 head, so the water will have a lot of kinetic energy to transfer to the turbine.***
There is a big drop, so the water will have a lot of potential energy to transfer to the turbine
4) A team of engineers works with a wind turbine. The team works with a model and tests different angles for the wind turbine blade. What would be the research question for this team? (1 mark)
Which angle converts the greatest percentage of wind kinetic energy into turbine kinetic energy?***
Which angle converts the greatest percentage of the potential energy of the wind into the kinetic energy of the turbine?

4) Which angle converts the greatest percentage of the kinetic energy of the wind into the kinetic energy of the turbine? Teehee is 100% right. Thanks! Thihi is right!! 100% Thank you!! BOYS LISTEN stop submitting your answers as a letter, everything will be wrong because for tests and quizzes the order of answers is random. Here are the answers to the Grade 8 Quick Check Using Potential and Kinetic Energy
1). Kinetic energy is highest at the bottom; the potential energy is highest at the top.
2). The kinetic energy of water would be greater at the bottom of the drop in river A than in river B.
3). There is a big drop, so the water will have a lot of kinetic energy to transfer to the turbine.
4). Which angle converts the greatest percentage of the kinetic energy of the wind into the kinetic energy of the turbine?
I promise they are right. If not, I’ll send you $100. Keep in mind this is the QUICK CHECK FOR POTENTIAL AND KINETIC ENERGY IN EIGHTH GRADE!! Only in eighth grade, I don’t sell $100 to a 6th grader just because he doesn’t know what grade it is. Have a good day everyone! the coffee bean is incorrect I got a 0 so thank you very much TeeHee is right for grade 6 answers I don’t know for 1st 2 3d 4th 5th 7th 8th 9th 10th 11th 12th Person is right for me Tehee is right use just his answers or just do your own work 1. Kinetic energy is highest at the bottom; the potential energy is highest at the top.
2. The kinetic energy of water would be greater at the bottom of the drop in river A than in river B.
3. There is a large head, so the water will have a lot of kinetic energy to transfer to the turbine.
4. Which angle converts the greatest percentage of wind kinetic energy into turbine kinetic energy? I hate Horace Mann, he ruined the lives of billions of children and billions of generations to come. why would you create the school Kinetic energy is highest at the bottom; the potential energy is highest at the top.
D
The kinetic energy of water would be greater at the bottom of the waterfall in River A than in River B. C
There is a big drop, so the water will have a lot of kinetic energy to transfer to the turbine. VS
Which angle converts the greatest percentage of the kinetic energy of the wind into the kinetic energy of the turbine? D tee-hee is correct thx π i got it @blindy33 got me a 4/4 so thanks ANSWER IN WORDS THE NUMBERS AND LETTERS ARE ALWAYS RANDOMIZED THEY WILL NEVER BE THE SAME!!! @Teehe you are 100% right your baka susssssssssssy Thanks Teehee I got 100% 4/4!!!!!!!!!!!! @blindy33 is 100% correct for grade 8 just got 4/4 Person is right! Thanks a lot!! nobody and tee-hee are correct!! thank youuu <33 thank you tee hi <3 B
B
D
A @blindy33 gave me a 3/4 but I probably read it wrong and it’s better than I would have gotten on its own. thx @blindy33 Elizabeth Afton IS CORRECT Elizabeth Afton is correctπ OMG YOU TROLLERS ARE WRONG TEEHEE IS CORRECT OMG TEEHEE is correct except for the last one. TEEHEE IS CORRECT I GOT 100% π Blindy, Person and Teehee are all correct. I don’t know what you got π Teeheehee got it all figured out, but be sure to read the answers carefully. The person is right. Please use person Blindy, Person and Teehee are all correct!! Thanks to you three! Before submitting check it out.. i got 3/4 correct answers because i clicked on the wrong one…but here are the answers.
1). Kinetic energy is highest at the bottom; the potential energy is highest at the top.
2). The kinetic energy of water would be greater at the bottom of the drop in river A than in river B.
3). There is a big drop, so the water will have a lot of kinetic energy to transfer to the turbine.

Two different rivers have the same height difference. In River A, this section of the river is a waterfall. In River B, this section has a hydroelectric dam. How does the energy differ between the drops of the two rivers?
The kinetic energy of water would be greater at the bottom of the drop in river A than in river B.
Turbines can be seen inside this hydroelectric dam. Why are they located at this particular height?
There is a big drop, so the water will have a lot of kinetic energy to transfer to the turbine.

I had gotten a 100% whether you trust me or not thanks for reading!
Have a nice day ! no name the letters change for everyone so my A could be ur d @TeeHee is 100% correct ;D
Ps: if you see my name, I never lie on replies, so watch out for me
~ The nerd tysm @tee hee is almost correct, except the first one is the highest kinetic energy at the top; potential energy is highest at the bottom correct canopies
1-b
2-c
3-c
4-a
and teehee is right what the answers are in letter form @Luna474 That’s not true. I have a 1/4 tysm. The answers are……
1.) a
2.) c
3.) c
4.) b The correct answers are
1. One
2.A
3.D
4.C
I just took the quiz and these are correct for 8th grade science at Connections Academy. Check my answers, as they might change.(2020)!!! is not written as 1. 1 is the highest kinetic energy at the bottom; the potential energy is highest at the top. The answers were 1)C 2)A 3)C 4)a The answers are:
1-D
2-B
3-B
4-C
These answers are for the quick check of the use of potential and kinetic energy for CCL grade 8 science, he got the last one wrong. teehe is completely wrong 1).A
2).A
3).C
4).C
