In a hydroelectric power plant, water is stored high above a turbine. As it falls, the water spins the turbine blades to generat
e electricity. Which form of energy does the stored water have? elastic potential energy
gravitational potential energy
radiant energy
vibrational energy
Hello there! Radiant energy has to do with energy from electromagnetic waves and water doesn't really have to do with that. C is out. Vibrational energy has to do with vibrating energy at different frequencies. In this case, D is also out. The stored water has to do with potential energy, because as you go up higher, there is more potential energy. Elastic potential energy has to do with an elastic object storing potential energy, while gravitational energy has to do with its height on Earth, and water is not an elastic object. It has to be gravitational potential energy, because water falls due to gravity and falls lower. The answer is B: gravitational potential energy.
When there is either a partial or complete tearing on ligaments that are responsible for supporting the joint of the ankle then it causes an ankle sprain.
Based on the exam findings as well as the loss in functionality of the ankle, an ankle sprain can be categorized as grade I, II or III.
In the given situation the 14-year-old girl has a grade II ankle sprain which is characterized by an incomplete tear of the ligaments along with moderate pain (as she rates it 5/10), moderate tenderness, loss of range of some functions, and swelling.
All of the characteristics of the sprain resemble those of the grade II ankle sprain tear and hence, it is characterized as a grade II ankle sprain.
