Considere un campo vectorial u que apunta radialmente hacia afuera de un punto p. la magnitud del campo en un punto q una distancia r del punto p es a k donde k es una constante positiva. calcule el flujo de este campo vectorial a través de una superficie esférica de radio r centrada en el punto p

What are chlorofluorocarbons and what impact do they have on the atmosphere?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
