Q1: Pick up the incorrect statement from the following :

ANS:B - an increase in temperature causes a tape to increase in length and the measured distance is too large

An increase in temperature can cause a tape to expand and increase in length. This phenomenon is due to the thermal expansion properties of the materials used in the tape's construction. Most materials, including metals and polymers commonly used in tapes, expand when heated and contract when cooled. When a tape is exposed to higher temperatures, its molecules gain energy and vibrate more, causing the material to expand. As a result, the overall length of the tape increases. This expansion can lead to inaccuracies in measurements, especially if the change in temperature is significant. In surveying and measurement applications where precise distances are crucial, changes in temperature can introduce errors in the recorded measurements. If the temperature increases during measurement, the tape lengthens, causing the measured distance to appear longer than it actually is. Conversely, if the temperature decreases, the tape contracts, resulting in a shorter measured distance. To mitigate the effects of temperature on measurements, surveyors and engineers often use correction factors or calibration adjustments to account for thermal expansion or contraction. Additionally, using materials with lower coefficients of thermal expansion or conducting measurements during stable temperature conditions can help minimize errors caused by temperature fluctuations.
