Answer 1

Systematic error – This error arises due to not arranging the instrument correctly. This is person error. Suppose we measure the length of the rod incorrectly or record the measurement incorrectly. This is our person mistake. So, this could be happens during experiment. Room temperature - This is main factor for the error in this experiment. When we take the same measurement in different locations, we get the different values due to changing the temperature. Even the length of the scale would also change while changing the temperature of the environment. So, room temperature could be the possible error in the experiment. Imperfection of instrument- When measuring instrument is not measured correctly, then, it can result the error in the measurement. So, wrong measurement by instrument would create the

more error.
