There is a stack of books on the floor. A piece of cardboard against the book, creating an inclined plane to the floor. A toy cart is placed on top of books. ( Look for diagram on "Elaborate with STEM" Tab and answer the following questions:

How does the height of the stack of books related to the potential energy?

In this setup, How can you potential energy be converted into kinetic energy?

Sketch a labeled potential energy diagram for the cart rolling down the ramp? Attach a copy.

Describe a technology that relies on the conversion from potential energy to kinetic energy to work.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

answer; /// i believe the correct answer is (thrombocytopenia); (a)

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
