(According to Chegg policy, only one question with multiple sub-questions will be answered. Please post the remaining in another question)
46. (a) The number of eggs in a basket
Since this is a mere number, it can be determined exactly.
(b) The mass of a dozen egg
This needs a scale measurement and cannot be exact. It must be measured with some uncertainty.
(c) The number of gallons of gasoline necessary to fill an automobile tank
The number of gallons could be a fraction. This must be measured with some uncertainity.
(d) The number of cm in 2m
Since 1m is 100cm, 2m is 200cm. This can be measured exactly.
(e) The mass of a textbook.
As with (b), this must be measured with some uncertainty.
(f) The time required to drive from San Francisco to Kansas City at an average speed of 53mi/h.
Since the distance between the two cities is known and the speed is given, time can be measured exactly.
