All of them.

I take this class rn too and those are answers
Hey I searched this up for you this is what I found! “Most are made of steel or cast iron, but in each case the alloy has been carefully chosen and the processing tailored to the application.”
Before calculating the volume of this cylinder, we must either convert the diameter to feet or the height to inches. I'll do the latter, to avoid getting a very small number.
Recall that there are
12
inches in
1
foot. Thus, we can state:
12
in.
1
ft.
=
x
4
ft.
x
=
12
in.
×
4
ft.
1
(ft.)
x
=
48
in.
Hence, the cylinder has a height of
48
inches.
Now, we can apply the formula for volume of a cylinder to effectuate our calculation. The formula in question is
V
=
a
base
×
h
, or
V
=
r
2
π
×
h
.
However, we know our diameter but we don't know our radius. As you probably know, the diameter is linked to the radius b the formula
d
=
2
r
. Solving for
r
and substituting:
r
=
d
2
r
=
12
2
r
=
6
∴
The radius of the cylinder measures
6
inches.
V

Note that this answer is in exact value. Rounded to two decimal places, the volume is
5428.67
in
Answer:
While air is compressed in a piston cylinder there are following types of irreversibilities
1.Due to finite temperature difference heat transfer take place between cylinder and surrounding.
2.Due friction force between cylinder and piston .
3.Compression process is so fast due to this ,it leads in the irreversibility of system.

The diagram above is supposed to represent 3 lightbulbs connected in series. The vertical lines in the middle are supposed to be a battery which powers the three light bulbs. If you put a voltmeter across one of the lightbulbs, it will read a voltage that is 1/3 of the voltage of the battery.
Answer
That reading you get across the one light bulb is The Voltage Drop.
