One way to visualize atmospheric pressure is to imagine a wedge-shaped column of air that extends from the surface to the top of the atmosphere. The weight of this column causes atmospheric pressure. There are proposals to send a robotic spacecraft to Venus that will deploy a balloon that will float in the upper atmosphere and study the planet. Explain why being higher in the atmosphere would reduce the atmospheric pressure on the spacecraft and allow it to survive for a longer period of time.

i was thinking more like reflects green light, just not sure

as technology advances, new experiments often expose problems in accepted theories. c

hope i

answer: b.

explanation:

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
