Compared to Earth's gravitational force on the space shuttle when in orbit, the force on a shuttle astronaut is: a) the same because both are orbiting at the same speed.
b) less because the astronaut has less mass than the shuttle.
c) more because the shuttle was built to orbit, but the astronaut was made to be on Earth.
d) the same both are zero because there is no gravity in space.
e) less because the shuttle pulls him around in orbit.

A. the same because both are orbiting at the same speed.

Explanation:

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

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
