Explanation:
Assuming no loss in energy when going up or down (i.e.neglect air resistance), the energies are the same at the maximum height as well as the ground.
(II) the initial energy is all kinetic (so is the final energy when it hits the ground), so
KE = (mv^2)/2 = 0.5kg * ( (15^2) m^2/s^2 ) /2 = 56.25 J.
(i) PE at top = KE at bottom = 56.25 J.

Answer:
Confirmation biases impact how we gather information, but they also influence how we interpret and recall information. For example, people who support or oppose a particular issue will not only seek information to support it, they will also interpret news stories in a way that upholds their existing ideas.
Answer:
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file. In short, it's A or D.
