Step-by-step explanation:
Work done in stretching a spring is
since 
F is the applied force, E is the elongation and k is the spring constant.
(a) Here, e = 16 cm = 0.16 m
(b) Here, e = 12 cm = 0.12 m
(c) The restoring force is the same as the applied force.
The miles the student biked in two weeks is 11 2/3 miles.
The distance the student bikes is given in fractions. Fractions are numbers that are made up of numerator and denominators. An examples of a fraction is 1/4. 1 is the numerator and 4 is the denominator.
In order to determine the distance biked in 2 weeks, the distance biked in a day has to be determined.
Distance biked in a day = (1/4 + 1/3 + 7/12)
14/12 = 1 2/12 = 1 1/6
Distance he would travel in 2 weeks
1 1/6 x 10
7/6 x 10 = 70 /6 = 11 2/3 miles
