Two astronomy students go to Japan, where one stands on the surface in the sunshine (where she is struck with photons from the sun) and the other goes down into a mine with a neutrino detection experiment is being conducted, arriving in time to witness a detection. Although the photon at the surface and the neutrino in the mine arrive at the same time, they had very different histories. Describe the journey each one took.

gravity

explanation:

truck y has a greater velocity than truck x.

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
