Arocket and a space station are both moving freely in deep interstellar space. the rocket is moving at speed 4/5 in the x direction as measured in the station’s (home) coordinate system. the rocket (other) coordinate system is in standard orientation relative to the station’s. an object is moving freely. observers on board the rocket measure the particle’s position to be x′ = 5s at time ′ = 4s and to be x′ = 8s at time ′ = 9s. show your work as you answer the following questions. a) what is the object’s velocity measured in the rocket coordinate system? b) what is the object’s velocity measured in the station’s coordinate system?

you have to draw the persons position over there

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
