What type of shape do objects in space make as they move according to the heliocentric model? elliptical perfect circles straight line zig zag

Answer : Option B) Perfect Circles

Explanation : In heliocentric model where sun is considered to be the center and earth and other planets revolves around it. The shape of the objects in the space is perfectly circle as they move around the sun.

Perfect circles    

Explanation:

Heliocentric model of the solar system was proposed by Nicolaus Copernicus. According to this theory, Sun is at the center of the Solar system and the earth along with other planets and moons revolved about in concentric circles. Later, Kepler gave the laws of planetary motion according to which the planets revolve about the sun in elliptical orbits.

Thus, the correct answer is: Objects in space make perfect circles as they move according to the heliocentric model

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
