If you were suddenly placed at an altitude of 100 kilometers (62 miles) above the earth, would you expect your stomach to expand or contract? explain why.

Stomach will be  expand.

Explanation:

Since, As altitude increases, the amount of gas molecules in the air decreases the air becomes less dense than air nearer to earth surface.

So, at an altitude of 100km , pressure inside the stomach will same as on earth but pressure outside the stomach will be less.

Therefore, Stomach will expand.

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
