dens =5000kg/m^3
vol.=.005m^3
so mass of particle=d*v=5000*.005=25kg
from 2nd newton's law.
(delta P)/time=force.
delta P means change in momentum =mv-mu
=25(10-5)=125kgm/s
so force=125/2=62.5N

Answer:
Good Touch – It feels, pleasant and good, it is a way to show care, love and help. Explain with the help of examples like when mommy hugs you or papa gives you a goodnight kiss or your grandparents hold you in their arms and you hold your friend’s hands while playing.
Bad Touch – Touches that make you uncomfortable and you feel unpleasant and you want to stop it there and then.
Again, use some examples to explain them like, it is a bad touch if you feel hurt, if you do not want to be touched, if someone touches your private parts without a reason, if someone touches you and tells you not to tell anyone, all these are examples of a bad touch.
