The force is directly proportional to the product of the masses or charges; the force is directed along the line that connects the two particles. Differences: Newton's law includes a minus sign while Coulomb's law does not; the gravitational constant G is many orders of magnitude smaller than the Coulomb constant k. The force varies as1/r^2the force is directly proportional to the product of the masses or charges; the force is directed along the line that connects the two particles. Differences: Newton's law includes a minus sign while Coulomb's law does not; like charges repel, like masses attract; the gravitational constant G is many orders of magnitude smaller than the Coulomb constant k.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

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
