If blood starts flowing backwards through a valve, stroke volume and ejection fraction would decrease. The heart's pumping action would be less efficient.
Any electrons flowing through a superconductor will show up as a regular electric current.
you pick it, and walk backward, so you don't walk through the ladder, you will still be lucky!
You'll die. Your heart is a muscle, which means you won't get any blood and oxygen flowing through your body.
damage the device, motherboard, or adapter.
The hang glider would lose lift and potentially be pushed backward, making it difficult to stay airborne or control the flight. The pilot would need to adjust their positioning and flight path to compensate for the reverse airflow.
Current stops flowing.
For a material with low viscosity the flowing is easier.
No, nothing will happen . Electricity is not flowing
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.

the earth was broken
A digital voltmeter will read negative voltage, if connecting backward. If the meter is an analogue type, the needle will go backwards and dip below the 0 on the scale.
