Choice A is correct, the kinetic energy of the wind turns the turbine which creates kinetic energy of its own, this rotational kinetic energy can be called mechanical energy and is used to create electricity.
I think about 67 students because if you divide 570 by the amount each person needs you get 67.0588235294 so you have to round down
Answer:
All samples of a given chemical compound will be composed of the same elements in the same proportion.
Explanation:
The law of constant composition or definite proportions states that "all pure samples of the same chemical compound contain the same proportions of the elements by mass". For example, every time water H₂O forms, it would always have the same proportion of hydrogen and oxygen.
Answer:
Since reactions occur as a result of collisions between particles, the more particles are in a reaction vessel, the higher the concentration of particles, the more collisions are possible. The more collisions that occur, the faster the reaction rate.
Explanation:
These are just some characteristics for a reaction to occur
