[Ques. 4] Multiplying a 2-significant-figure number by a 4-significant-figure number and then dividing the product by a seven-significant-figure number yields a number with how many significant figures?
a. 6/7
b. 1
c. 2
d. 13
e. 8/7
[Ques. 5] There are other ways of expressing uncertainty besides significant figures. For example, suppose a quantity is known to have a value between 20.4 and 20.0, and our best estimate of the value is midrange at 20.2 . We could write the number as 20.2 +/ 0.2 and say that the number has a 1 uncertainty. We would also say it has 3 significant figures. If we square a number with 1 uncertainty (i.e., 2 parts in about 200) and 3 significant figures, what results?
a. A number with 1 uncertainty and 3 significant figures.
b. A number with 2 uncertainty and 3 significant figures.
c. A number with 2 uncertainty and 2 significant figures.
d. A number with 1 uncertainty and 2 significant figures.
[Ques. 6] Assume when using a meter stick measuring can be done so that the last significant figure is in the tenth of a millimeter digit. If you are measuring an object with length between 25 and 53 cm, how many significant figures will result if you only use the part of the meter stick between the 3-cm and 85-cm positions?
a. 1
b. 2
c. 3
d. 4
e. more than 4
[Ques. 7] Assume when using a meter stick measuring can be done so that the last significant figure is in the tenth of a millimeter digit.
