If you walk 2km north then 1km east what is the magnitude of the distance?​

What are the north and south poles of a solenoid change with?

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

1) a child holds two dogs on two separate leads. the dogs are pulling in different directions. one is pulling a force of 20n north and one is pulling 15n eastwards. calculate the resultant force on the child. state the direction. (use the parallelogram of forces) 2) a force of 20n acts horizontally on an object. a second force of 5n acts at 60 degrees to the first one. calculate the resultant force. worth 20 points, need answers asap with method you x
