Answer:
is there supposed to be a pic and abcd options?
The speed of the ball just before impact was v=√(2gh) = 6.26m/s. The acceleration is twice this over the time (twice because the second speed is the same in the other direction, meaning the total change in speed is 2V)
a = 12.52/0.10 = 125.2m/s²
The force is F=ma, so F = 0.5kg·125.2m/s² = 62.6N
That would be a conduction.
This is true; it needs to balance it’s charge. However, it could also be negative charges as well.
Well...they came from a single bacteria and self produce them...if they grew.there will be millions of them...
