Answer:
Child maltreatment or child abuse is a phenomenon of sexual, physical, and/or psychological abuse of children.
Five different psychological perspectives of childhood maltreatment are as follows:
- Poverty is one of the biggest cause of childhood maltreatment that impact once psychological health.

A "folk" remedy is something you choose to eat, take, or do,
in order to correct some health issue, because your friend,
your grandmother, your religion, your shaman, your astrologer,
or your medicine man says that it's the right thing to do.
It may or may not be effective, and it may or may not even be
safe. What distinguishes it from mainstream medicine is that
its practices are based on hearsay, and have not been subjected
to scientific methods of investigation and evaluation.

Answer:
0.05J
Explanation:
Since the total energy is conserved I.e the mechanical energy, the energy present in the system are kinetic energy, potential energy and the gravitational potential energy. The expression for this energy is written as
Kinetic Energy=1/2MV^2
Potential Energy=1/2Kx^2
Where K is the spring constant and X is the extension the spring experience.
Gravitational Energy=mgh
Where m=mass, g=gravity constant and h=height
Hence for a spring with spring constant 10N/m and extension 0.1m the potential energy can be calculated as
PE=1/2Kx^2
If we substitute values we arrive at
PE=1/2×10×0.1^2
PE=0.05J
