Micrometer Questions:

Question #1:

How do you find the length of micrometer?

in lab we looked up a specimen under 4x 10x 40x

when I looked low the micrscope 4x measure 7.26 , 10x measure 15.18 and 40x manoeuvre 62

how do i encounter the length of µ


the girl that was movement incoming to me wrote something like 182 for 4x / 10x : 100 or 148 and 40x :1705 i couldnt see it substantially

so what would 4x and 10x and 40x each be? how do you do this ??

Question #2:

how do you find the length of micrometer?

in lab we looked up a specimen low 4x 10x 40x

each measure
4x = 7.26
10x=15.18
40x=62

how do i find the size of µ
i need for each digit 4x , 10x and 40x

I couldnt wager very substantially but I saw this girl indite for 4x : 182 , 10x: 100 and 40x?

Question #3:

Physics problem can someone please help I don't understand it?

a defibrillator is utilised to uphold a person's hunch after it stops beating. energy is delivered to the hunch by discharging a condenser finished the embody tissues nearby the heart. if the capacity of the defibriliator is 9 micrometers and the energy delivered is to be 300 J, to what potental differnce staleness the condenser be live

Question #4:

Why is micrometer more accurate than caliper?

The digital calliper displays threesome digits, but the digital calliper displays quaternary digits because the accuracy of activity of a micrometer is greater than that of a caliper. Explain why the quality of the calliper is greater than that of the caliper.

Question #5:

PHYSICS Distinction level question. Someone Help me out please?

So I have been doing this practical in lesson.

Here is what I wrote for the Merit part.


I hit utilised the micrometre, rather than the vernier callipers or cadence rule to measure the diam of the wire because the micrometre measures to the nearest 100. It is more faithful and the results then are more reliable.
I have used an ohmmeter in one on my methods. This is because an ohmmeter gives you a hurried and cushy result in the experiment. It’s rattling ultimate to use and country to read.
In other part of my technological experiment, I hit used an ammeter/milliammeter and voltmeter. An ammeter is very precise. It gives you a more faithful respond so the results become correct. The voltage/ammeter also gives more faithful answers.
The choice of shunts / scales I utilised was the 1 Volt scale. It is really hurried and ultimate to feature and to achievement the results. This is because there is exclusive digit harry which uses the whole scale. .
The ammeter/milliammeter is more fit than an linear meter to measure underway through the accommodate in the experiment. This is because there was no parallax nonachievement on the digital scale, and on the linear cadence shown this error during the experiment. A parallax nonachievement effectuation hunting from a assorted angle.


The QUESTION FOR THE DISTINCTION now:


Evaluate the variables in operation of instruments utilised and how they could be optimized. How they can be used in the most trenchant way .
For your methods , explain the actions you undertook to ensure accuracy and precision. Your discussion should allow both practical steps condemned and analytical techniques utilised and the reason for these actions.







Can Anyone Help me out?

Thank you!

Question #6:

I REALLY NEED HELP IN THIS PART OF THE QUESTION!?

The photoresist broadness in conductor manufacturing has a mean of?
10 micrometers and a accepted deviation of 1 micrometer. Assume that the thickness is normally distributed and that the thicknesses of different wafers are independent.

If the stingy broadness is 10 micrometers, what should the accepted deflexion of thickness equal so that the probability that the average of 10 wafers is either greater than 11 or inferior than 9 micrometers is 0.001? Please ammo your respond to 4 decimal places.

I got this support but the answer is not correct:
Since the normal organisation is symmetrical, and the total probability at both ends is to be 0.001, we requirement the probability at each end to be 0.0005

i.e. we poverty the standard reason same to a additive quantity of 0.9995

The table at
…
only goes up to 0.9990, but just below that is added table headed
"Far right tail probabilities"
It gives the probability of Z exceeding 3.3 as being 0.0004834, which is near sufficiency to 0.0005
So we require that 1 micrometer edge to be coequal to 3.3 accepted deviations.
Therefore std dev = 1/3.3
........................ = 0.3 correct to one figure. and 0.3030 is not precise too

Question #7:

The photoresist thickness in semiconductor manufacturing has a mean of?

10 micrometers and a standard deviation of 1 micrometer. Assume that the broadness is normally distributed and that the thicknesses of assorted wafers are independent.

If the mean thickness is 10 micrometers, what should the standard deflexion of thickness coequal so that the probability that the average of 10 wafers is either greater than 11 or less than 9 micrometers is 0.001?

Question #8:

Please help, The photoresist thickness in semiconductor manufacturing has a mean of 10 micrometers?

a accepted deflexion of 1 micrometer. Assume that the thickness is ordinarily diffuse and that the thicknesses of assorted wafers are independent.


Determine the number of wafers that needs to be rhythmic much that the quantity that the cipher thickness exceeds 11 micrometers is 0.01.

Question #9:

If an unfertilized human egg is 0.1mm, then how many micrometers is it?

Question #10:

URGENT: An atom of rhodium (Rh) has a diameter of about 2.7 x 10^-8 cm?

How some Rh atoms would have to be placed lateral by side to movement a indifference of 4.5 micrometers μm ?

If the corpuscle is acknowledged to be a sphere, what is the intensity in m 3 of a azygos Rh atom?

Please respond within the hour, and I module give the first correct answer 10 points! Thank you to every in advance! :
