Idk I need answer choices.
Answer:
5.When the skater has high PE it the skater is slow, when the skater has low PE it's going fast. When the skater has high KE the skater is going fast, when it has low KE he's going slow
6. If you double the speed of an object, the kinetic energy increases by four times.If you double the mass of an object, you double the kinetic energy. potential energy increases as weight and height increases
7.The skater won't stop untill he runs out of kenetic energy.It depends on the potential energy to detemines how far it will go.What would slow you down is if the track was long,so eventually it would were out the energy
Hope it helps ;3

Showing that the spectra of stars depended on the ___temperature_____ and the ____degree of ionization of elements _______ in their atmospheres.
She showed that stars were mainly ______ hydrogen________ with the next most abundant element being ______ helium ________.
Explanation:
Cecilia Payne worked at the Harvard College Observatory (HCO) where she analyzed for months the spectra of hundreds of stars; she aimed to calculate the elements present in them; and from her observations and studies over the years she discovered the information quoted above.
