A sled weighing 1.0 X 10 N is held in place on a frictionless 20 degree slope by a rope attached to a skate at the top. The rope is parallel to the slope. What is the normal force of the slope acting on the sled

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

What is friction? how does it affect the motion of an object?

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