You need to construct a 200 pF capacitor for a science project. You plan to cut two L×L metal squares and place spacers between them. The thinnest spacers you have are 0.400 thick. What is the proper value of L ?

The proper value is 95 cm

Explanation:

Capacitors are a very common electronic components used to store charge for a period. The simplest kind of capacitors (and very studied on physics class ) are the two parallel plates capacitor. It consists of two parallel plates and some space between them, one plate is connected to a positive terminal of a source of voltage and the other pate is connected to the negative terminal. The capacitance of a parallel plate capacitor is:

with d the distance between the plates, A the area of the plates and εo the permittivity of vacuum that is

Knowing the area of a square plate is A=LxL = :

Solving for L:

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

the answer is false
