Answer:
building footprint is 21000 sf
Explanation:
given data
floors = 8
total square footage = 168000 sf
to find out
building footprint
solution
we know building footprint is area where building built up same as perimeter of any building plan
so here
we have calculate here total perimeter
building footprint = ........1
put here value
here all floor are equal
building footprint =
building footprint = 21000 sf
so building footprint is 21000 sf
Answer:
The correct answer is option '5': The type of metal from which the plate is made.
Explanation:
According to the principle of photoelectric effect we know that electron's are only emitted from a surface of metal if the frequency of the light is larger than a threshold frequency that depends on the metal and is known as threshold function of the metal. The ejection of the electrons is independent of intensity of the incident light meaning any light of frequency lower than work function will not eject electrons from the metal no matter whatever the intensity of the light, or the surface area or thermal conductivity, time of illumination.
