If the zero level for the gravitational potential energy is selected to be midway down the slope, 5.50 m above point b, find the initial potential energy, the final potential energy, and the change in potential energy as the skier goes from point to ® in the figure. initial kj k) kj final change need ? man use the worked example above to you solve this problem. a 59.0 kg skier is at the top of a slope, as shown in the figure. at the initial point d, she is 11.0 m vertically above point ® (a) setting the zero level for gravitational potential energy at ®, find the gravitational potential energy of this system when the skier is at and then at b. finally, find the change in potential energy of the skier-earth system as the skier goes from point to point

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

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
