(1) Sara said that it might rain tomorrow.
(2) Khalid said that he played football yesterday.
I'm laughing at this first question because it doesn't seem necessary to know for graduation in the future lol.... Okay so the answer is D. because the whole paragraph was saying what he was packing and that he was excited for his trip so it doesn't make sense to go off topic about how far away his house is from the camp or that he spent last summer somewhere else and that there will be horses there. For an ending, you want to make sure its an ending point and not an unnecessary sentence.
Answer:
C. Your friend is incorrect, at this point, the cannon ball just has potential energy.
Explanation:
Potential energy is the kind of energy that an object has due to its position.
The unit for energy in the International System of Units (SI) is the joule, which has the symbol J.
Potential energy is usually related to forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space.
These forces, receive the name of conservative forces and can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential.
