What is tangential acceleration and its magnitude 12. if a projectile that was launched from the ground with an initial velocity 100 m/s in the direction 30° north of east collides a rocket that was fired due east 4s after the projectile reached its highest point, how high up was the rocket fired and with what velocity given that the rocket has a constant velocity and was fired when the projectile was over head? 13. a car has a constant acceleration of 0.300 m/s2 and a horizontal velocity of 8.00 m/s at the moment the care is at the top of the rise of the roadway that is shaped like a circle of radius 500 m. what is the magnitude and direction of the total acceleration vector for the car at this instant?

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
