Work = Force x Distance = F x 0
Work = 0 J
A go up stairs = 10s
B go up stairs = 20s
C go up stairs = 30s
Power is influence by
the time taken to go up stairs.

Water - added - ballast tank - increase density
Why tubing Visking - rinse
- distilled water?

Hydrogen - undergone - nuclear fision - expand
Outer core drift to the space
Hydrogen used up
