The spring is located on Earth and nas a linear mass density ot 1.23 g/m (grams per meter). What is the spring constant of the spring? 18.7 N/m What is the uncertainty in the spring constant, R? You may assume g is known precisely witn no uncertainty. 0.80 N/m Always remember to present the uncertainty witn the same number of decimal places as the value.

The spring is pulled down 2.20 ± 0.30 cm and released. A stopwatch is used to measure the time it takes the spring to oscillate 10 times, IOT, (ie trom max height to min height and back to max height ten times). This is repeated another 2 times. The measurements are recorded below. trial 1 trial 2 trial 3 What is the period for a single oscillation? .61 Correct What is the uncertainty in the period? 0.018 Co rrect What is the spring constant, R, for the spring? 10 T (s) 6.26 5.91 6.08 31.74 Correct N/m What is the absolute unceäainty in the spring constant? 2.44 N/m Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings    Ink Drawings Ink Drawings Ink Drawings Ink Drawings  Ink Drawings Ink Drawings Ink Drawings Ink Drawings

Select one: x axis: gx, y axis: m x axis: m, y axis: x x axis: m, y axis: gx x axis: mg, y axis: x x axis: x, y axis: mg x axis: x, y axis: m Untitled picture.png Machine generated alternative text: Question 8 Marked out of 200 Flag question In the second part ottne experiment (the indirect method) you will be measuring the period, T, ot an oscillation of the spring and the mass hanging trom the spring, m. wnicn of the following options will give you a straight line graph witn a gradient equal to the spring constant, R? Select one: m , y axis: T2 a. x axis: T2, y axis: 2 TT m 5. x axis: T2 y axis: m c. x axis 4 m , y axis: T2 d. x axis: e. x axis: 2 TV m , y axis: T T2 y axis: 4Tr2m t. x axis Ink Drawings Ink Drawings Ink Drawings Ink Drawings        Ink Drawings Ink Drawings Ink Drawings
