Answer:
6.86 m/s
Explanation:
velocity of the gasoline through the hole would be

As the height would decrease, the velocity of the flow would decrease.
If the lid of the tank would be closed, the pressure would reduce. so, again the velocity of the flow would reduce.

Answer:
1. The current will drop to half of its original value.
Explanation:
The problem can be solved by using Ohm's law:

where
V is the voltage across the circuit
R is the resistance of the circuit
I is the current
We can rewrite it as

In this problem, we have:
- the resistance of the circuit remains the same: R' = R
- the voltage is decreased to half of its original value: 
So, the new current will be

so, the current will drop to half of its original value.
