The correct option are as follows:
estimating temperature to the nearest tenth of a degree
estimating the mass of the sample to the nearest tenth of a gram
the position of the cups of sand and water under the heat lamp
<u>Explanation:</u>
Error is an uncertainty or the amount of deviation in a physical quantity. There may arise some deviance while measuring physical quantity due to approximation.
Instrumental, environmental, procedural, and human are some of the common sources of error. The error can be classified into two types:
i) Random error
ii) Systematic error
Types of error are determined based on the deviation in the result. While observing the temperature of something, the temperature should be noted to the nearest tenth of a degree. In similar way, the mass of the sample should be estimated to the nearest tenth of a gram.
