Answer:
Between 120 and 180 seconds
Speed = Distance/Time = 100 km / 4 hours = 100/4 km per hour = 25 kph
Answer: the ladder
Explanation: since the energized conductor is already in contact with the ladder there by making electric current to flow. The base of the ladder is on the ground there by making the circuit to be complete and causing electrocution.
P.E = mgh
This is the formula for potential energy.
This is where m is mass, g is the acceleration due to gravity, and h is height.
All you have to do is multiply all these numbers together.
