Friction occurs when the surfaces and heat of two surfaces grind against each other.
I think these are the answers
this process is called parellelogram method of resolving vectors.
Answer:
5kgm
Explanation:
convert cm to m and g to kg
250/1000=0.25kg
5/1000=0.05m
then find the density
density=mass/volume
=0.25kg/0.05m
=5kgm
Answer:
we know that current = charge/time
Explanation:
therefore,
A = 8000/120
A => 66.666.... amperes
