Answer:

1963.93 Moles

Explanation:

-We know the standard conversion ratio for the volume of a mole is 1 Mole=22.4L

Given volume of rooms as 13.0ft\times12.0ft\times10ft=1560 ft^3

Convert the volume into liters:1560\times28.2l=43992l

#From our conversion ratio above, we get the volume of air molecules in moles as:

V_m=\frac{43992L}{22.4L}\times 1\ mole\\\\=1963.93\ Moles

Hence, the volume of air molecules is 1963.93 Moles

Answer:

0.500 T

Explanation:

Since the change in time and the number of coils are both 1, I set the problem up to be 1.3=(1.5(x)-13(x)). I then plugged in numbers for x until I got the answer to be 1.3 V.

azamat
We assume a=const (acceleration is constant. We apply the equation
v^2=v0^2+2as where s is the distance to stop v=0(m/s). We find the acceleration from this equation
a=-v0^2/(2s)=-70^2/(2*3) =-816.7 (m/s^2)

We know the acceleration, thus we find the distance necesssary to stop when initial speed is v=140 (m/s)
s=-v0^2/(2a) =140^2/(2*816.7)=12 (m)

A certain part of a computer chip has a length of 1.5 micrometers. How many meters is this ?
Alchen [17]

When you're working with units of measure, "micro" almost always means "millionth", or 1 x 10⁻⁶ .  And that's exactly the case in this example.

"1.5 micrometer" = 1.5 millionths of a meter, or <em>1.5 x  10⁻⁶ meter.</em>
