It is often useful to have an intuitve feel for the magnitude of physical units. in physics, force is typically measured in units of newtons (n). in each of the following scenarios, decide which value for the force is most reasonable, and place the appropriate label from below into the box. the force you exert on the handle of a screen door as you open the door is on the order of . the force exerted by a honeybee as it lands on a flower is on the order of . the thrust force produced by the engines of a passenger jet as it takes off is on the order of . the weight of the largest aircraft carriers is on the order of . 0.1 n 0.001 n 10 n 100,000 n 1,000,000,000 n

The force you exert on the handle of a screen door as you open the door is on the order of 10 N. The force exerted by a honeybee as it lands on a flower is on the order of 0.001 N. The thrust force produced by the engines of a passenger jet as it takes off is on the order of 100,000 N. The weight of the largest aircraft carriers is on the order of 1,000,000,000 N.

Explanation:

In the first case, force made by hands and arms movement is in the range of 1 or 10N. In the second case, we are talking of a honeybee, an insect that weighs grames. The third case is the force required to make a plane take off (it is %10 of the thrust force of a plain with a weight of 300000N to 1000000N). In the last case, we are talking of the largest aircraft carriers, steel monsters that weight thousand of tons.

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
