Ok so she says that electric dipoles are of opposite charge but equal magnitude at 3:40. But then at 5:33 she shows 2Q with -Q, at that point the magnitude of the 2Q particle wouldn't be equal to the -Q so they wouldn't be electrical dipoles right?
Well the ground doesn't move correct? So the river moves 6 km/hr relative to the ground. Since the river is moving 6 km/hr and the boat is moving 14km/hr relative to the river, then you subtract their speeds and so from the perspective of the river the boat is moving 8km/hr.
Honestly I'm just...
Homework Statement
If a river is going 6 km/hr relative to the ground, a boat is going 14 km/hr relative to the river, and a man is jumping from one end of the boat to the other at 6 km/hr relative to the river. What is the speed of the man relative to the ground?
