The uncertainty of the heavy object if the scale remains constant is 0.24 lbs.
<h3>What is uncertainty in measurement?</h3>
- This is the error associated in an attempt measure the object accurately.
The percent uncertainty in measuring the light weight object is calculated as follows;
![= \frac{0.034}{11} \times 100\%\\\\= 0.309\%](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.034%7D%7B11%7D%20%5Ctimes%20100%5C%25%5C%5C%5C%5C%3D%200.309%5C%25)
The uncertainty of the heavy object if the scale remains constant is calculated as follows;
![= \frac{0.309}{100} \times 78.0 \ lbs\\\\= 0.24 \ lbs](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.309%7D%7B100%7D%20%5Ctimes%2078.0%20%5C%20lbs%5C%5C%5C%5C%3D%200.24%20%5C%20lbs)

Answer:
neutral
Explanation:
3p - 3e = 0 and that leaves 2 neutrons so it will be neutral
Answer:
Explanation:
mass = m =890 g volume = v =100cm³
Density = m/v =890g / 100cm³ =8.9g/cm³
Answer:
Three other length for which resonance will occur is 66 cm, 110 cm and 154 cm
Explanation:
As we know that the length of the pipe is 22 cm
Now let say it is in 1st harmonic state so we have
![\frac{\lambda}{4} = L](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%7D%7B4%7D%20%3D%20L)
so we have
![\frac{\lambda}{2} = 2L](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%7D%7B2%7D%20%3D%202L)
So we have
![L_1 = L + \frac{\lambda}{2}](https://tex.z-dn.net/?f=L_1%20%3D%20L%20%2B%20%5Cfrac%7B%5Clambda%7D%7B2%7D)
![L_1 = L + 2L](https://tex.z-dn.net/?f=L_1%20%3D%20L%20%2B%202L)
![L_1 = 22 + 2L](https://tex.z-dn.net/?f=L_1%20%3D%2022%20%2B%202L)
For N = 1
![L_1 = 66 cm](https://tex.z-dn.net/?f=L_1%20%3D%2066%20cm)
For N = 2
![L_2 = 22 + 88](https://tex.z-dn.net/?f=L_2%20%3D%2022%20%2B%2088)
![L_2 = 110 cm](https://tex.z-dn.net/?f=L_2%20%3D%20110%20cm)
For N = 3
![L_3 = 22 + 132](https://tex.z-dn.net/?f=L_3%20%3D%2022%20%2B%20132)
![L_3 = 154 cm](https://tex.z-dn.net/?f=L_3%20%3D%20154%20cm)
To determine whether an object is in motion or not, you first
need to specify a reference point, because there's no such
thing as "real" motion, only motion relative to something.
Once you've named the reference point, you have to look at
the object at two different times. Each time you look at it, you
measure its distance and direction from the reference point.
If there's any difference in these measurements from one time
to the next, then the object has had average motion during the
period between the two observations.
That's the best you can do ... find average motion during some
period of time. You can never definitely tell whether or not the
object ever stopped during that time. But you can sneak up on
it by making the time period between the two observations shorter
and shorter.
