Explanation:
Significant figures of a number written in positional notation are digits that carry meaningful contributions to the measurement resolution of the number.
Answer:
A production certificate Shows that the aircraft met FAA construction and performance standards
Explanation:
Federal Airport Authority (FAA), is the body that check the standard operations of air craft activities in a country.
Answer:
a)P/Po=0.263
b)γ=1.33 So gas is triatomic
c)
Explanation:
a)
initial pressure = Po
Initial volume = Vo
Final volume = 3.8 Vo
Lets take final pressure is P
we know that for free expansion process
PV= Constant
Po x Vo = P x 3.8 Vo
P=0.263 Po
So
P/Po=0.263
b)
Now gas is compressed in adiabatic manner
Final pressure = 1.56 Po
=1.56 Po
We know that for adiabatic process
γ=1.33 So gas is triatomic
c)
We know that average kinetic energy given as
\
I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
