1. Durante el despegue, un avión comercial alcanza entre 250 y 290 km/h, dependiendo de distintas variables como la resistencia del viento, la capacidad de peso o el uso de dispositivos de alta elevación. Para el ejercicio tenemos avión se mueve con velocidad de tal manera que, con el aire en reposo, su velocidad es 290 km/h en la dirección 35° noreste, respecto a la horizontal Espacio para el dibujo de los puntos ayb. a. Dibuje el avión junto con el vector velocidad, b. Dibuje las componentes rectangulares vector velocidad. Las componentes rectangulares de la velocidad son: A Vox = 354,02 Vay = -505,59 = 237,55 Voy = 166,33" = 354,02 D. Vex = 237,55 Voy = -166,33 5 B. Vox km C Dax Voy = 505,59 km​

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
