Question

Q. If the percentage error of measurement in mass and velocity are 4percent and 2percent what is the percentge error in kinetic energy ?

​

Answer 1

Given:

Percent error in mass of kinetic energy is 4% and 2%

Find:

Error in kinetic energy

$k.e \: = \frac{1}{2} \times m {v}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \: \frac{∆m}{m} \times 100 + 2 \times \frac{∆v}{v} \times 100 \\ \\ \frac{4m}{m} \times 100 + 2 \times \frac{ 2v}{v} \times 100 \\ \\ = 4 + 2 \times 2 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = 8\% \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

percent Error is 8 %

'm' will get cancelled 100 will get cancelled and 'v' will get cancelled.

Answer 2

Answer:

A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
