An average reaction rate is calculated as the change in the concentration of reactants or products over a period of time in the course of the reaction. an instantaneous reaction rate is the rate at a particular moment in the reaction and is usually determined graphically. the reaction of compound a forming compound b was studied and the following data were collected: time (s) [a] (m) 0. 0.184 200. 0.129 500. 0.069 800. 0.031 1200. 0.019 1500. 0.016 what is the instantaneous rate of the reaction at t=800. s?

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

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
