Acharged wire of negligible thickness has length 2l units and has a linear charge density λ. consider the electric field e-vector at the point p, a distance d above the midpoint of the wire. the field e-vector points along one of the primary axes, ywhat is the magnitude e of the electric field at point p? throughout this part, express your answers in terms of the constant k, defined by k=1/(4πε)

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
