The linear​ speed, v, of a point a distance r from the center of rotation is given by v=​, where ω is the​ speed in radians per unit of time. The linear​ speed, v, of a point a distance r from the center of rotation is given by v= ▼ r omega commarω, StartFraction r Over omega EndFraction comma r ω, StartFraction omega Over r EndFraction comma ω r, where ω is the ▼ angular linear total speed in radians per unit of time.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

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.
