Answer: D
Explanation: Look at the figure, we can conclude that the correct answer is
X: Low potential energy
Y: High potential energy
Z: Flow of electrons
Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.
Since the arrow is pointing to X, that means
Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.

Answer:
Explanation:
Given
Mass
Spring constant
Compression in the spring
When the mass leaves the spring, the elastic potential energy of spring is being converted into kinetic energy of mass i.e.
The kinetic energy of the mass is 1.102 J.
Answer:
D) examine a person for diseases
Explanation:
Only an X-ray can examine a person for diseases and broken bones because it is used to see what is happening on the inside of our bodies.
