The speed of light is said to be about 186,282 miles per second & 99.9999991% the speed of light (speeds reached on particle accelerator) is 186281.998323 miles per second. Technically if it moved only 40 mph faster it would be enough to be at light speed but the universe far more than compensates by moving 41 miles per second already.
The vernier scale subdivides the least count from the main scale into 10, 50 or 100 subdivisions. Vernier scales are found on a wide range of instruments. In Section 2 we will discuss the vernier caliper. Any instrument that uses a vernier will have two scales, a main scale and a vernier scale as is seen in Figure 2. A measurement is made by.
The uncertainty of the measurement should be given with the actual measurement, for example, 41.64 ± 0.02cm. Here are some typical uncertainties of various laboratory instruments: Meter stick: ± 0.02cm. Vernier caliper: ± 0.01cm. Triple-beam balance: ± 0.02g. Graduated cylinder: 20% of the least count.
micrometer has resolution of 0.01mm and Vernier caliper has resolution of 0.1mm. for single measurements you use uncertainty of half resolution and if you have many readings then use uncertainty as half of range. Scienceshorts said that the uncertainty would be its resolution as you take two measurements when using something like a ruler and.
The least count of vernier callipers is also known as the vernier constant. It is defined as the difference between one main scale division and one vernier scale division. It is mathematically given as: VC = 1 MSD – 1 VSD. When there are n divisions on the vernier scale which coincides with (n-1) division on the main scale, then the least.
