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

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
