GO Three digital clocks A, B, and C run at different rates and do not have simultaneous readings of zero. Figure 1-6 shows simultaneous readings on pairs of the clocks for four occasions. (At the earliest occasion, for example. B reads 25.0 s and C reads 92.0 s.) If two events are 600 s apart on clock A, how far apart are they on (a) clock B and (b) clock C? (c) When clock A reads 400 s, what does clock B read? (d) When clock C reads 15.0 s, what does clock B read? (Assume negative readings for prezero times.)

- Explain why, when defining the length of a rod, it is necessary to specify that the positions of the ends of the rod are to be measured simultaneously.arrow_forwardA pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled.

Exactly at noon, as determined by the WWV time signal, on successive days of a week the clocks read as in the following table. Rank the five clocks according to their relative value as good timekeepers, best to worst. Give the number of the correct clock in each case. Which clock is (a) the best timekeeper?

How many nanoseconds slow will the moving clock be compared with the Earth clock, at the end of the 2.00 h interval? answer in ns pleasearrow_forwardA student wakes up late and runs to school, covering a distance of 2.55 km in the direction of [N20degrees E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W50degreesS]. a) What is the students total displacement? b) If the total time taken by the student to run to school then over to the friend’s house was 25 minutes, what was her average velocity?arrow_forward
- An athlete has learned enough physics to know that if he measures from the earth a time interval on a moving spacecraft, what he finds will be greater than what somebody on the spacecraft would measure. He therefore proposes to set a world record for the 100-m dash by having his time taken by an observer on a moving spacecraft. Is this a good idea?arrow_forwardVector C has x-component -1.54 and a y-component -4.53. What is the angle measured counter clock wise from +x axis in degrees.

Label all axes properly, and draw a best-fit line through the data points. Determine the slope of the best-fit line. Based on the slope, what type of motion does the mass do? Now assume that the motion is described by From the given values for t and x, calculate the acceleration a for each measurement and write it down in a table. Be sure to add the proper unit. For the acceleration, find the average, the standard deviation, standard deviation of the mean and 2σ-uncertainty.
