Explanation:
Number of Cm neutrons = 242 - 96 = 146
Explanation:
We know that,
Energy = .......... (1)
and, Energy = ............ (2)
Now, equating both equations (1) and (2) as follows.
=
v =
=
=
= m/s
or, = 18 km/s
Thus, we can conclude that initial speed the electron must have in order to reach an infinite distance from the sphere and have zero kinetic energy when it gets there is 18 km/s.
The sand provides a rough surface on top of the ice for the cars' tires to grip onto. It provides more friction. Salt melts the ice and often provides more friction (the disadvantage is that it eats concrete!).
