3/8 times 2/5 is 6/40 or 0.15. Just multiply straight across
First divide 32 by 8
32/8
=4
Then multiply the 4 by 3 to find out how many students in the class like to ride their bicycles to school
4x3
12 students is your answer
The weight (or mass) is irrelevant.
The period t = sqrt(2*pi*sqrt(l/g) where g is the acceleration due to gravity.
so t = 2*pi*sqrt(5/9.8) = 4.49 seconds.
Frequency = 1/period = 0.223 Hertz.
26 because 10 is less than 26 and so is 24
