Explanation:
...domains are aligned which creates a magnetic field.
... are not always aligned so the resulting element had no apparent magentism
For speed you can differentiate the equation, for acceleration you can again differentiate the equation .
at t=0 the particle is slowing down , when you get equation for velocity put t=0 then only -1 is left
it is true. the trajectory reaches the value of zero at the top

1 kcal = 1*10^3 cal
or
=1000 cal</span>
