Q13.
A student is collecting water as it runs into a
measuring cylinder. She uses a clock to
measure the time interval between
measurements. Figure 1.15 shows the level
of water in the cylinder at two times, together
with the clock at these times. Calculate:
a the volume of water collected between
these two times
b the time interval.
Answers
Answer:
a. 55cm³
b. 31s
Explanation:
a. Volume of water collected at 1st time= 15cm³
Volume of water collected at 2nd time= 70cm³
Volume of water collected between both times= (Volume collected in 2nd) - (Volume collected in 1st)
= (70) - (15)
= 55cm³
--------------------------------------------------------------------------------------------------------------
b. Time measured in 1st try= 12s
Time measured in 2nd try= 43s
Time interval= (Time in 2nd) - (Time in 1st)
= (43) - (12)
= 31s
