Simple Question: Measurements of length & mass ZZZ

AI Thread Summary
Dust on samples and measuring devices can lead to inaccurate measurements, necessitating regular cleaning to ensure precision. Irregular samples can cause variations in mass and length readings, suggesting the need for standardized sample shapes or averaging multiple measurements. A slope in the balance affects weight readings, which can be corrected by using a spirit level to ensure the balance is horizontal. Other potential sources of error include temperature fluctuations and improper calibration of measuring instruments, which can be mitigated through routine checks and calibrations. Addressing these errors is crucial for obtaining reliable measurements in length and mass.

Discuss the effects of the following sources of errors on Measurements of length & mass. and suggest metods to overcome them:

1- Existing of a dust on both the sample and the measuring devices.
2- Irregularity of the samples.
3- Slope of the balance from the horizontal line.
4- Other sources.

Do you want to suggest something first? For me, 3 would be as simple as using a 'spirit-level' or horizontal surface to sort out.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
