Question

14. State the condition under which the distance-time graph of an object is a horizontal line parallel to the axis of time 15. State the factors on which the time period of a simple pendulum depend. 16. What is horology?​

Answer 1

Answer:

14. Considering the x-axis to be the time axis, the plot will be parallel to the time axis (a horizontal line) whenever the velocity of the studied object is zero, i.e.: when the position remains constant throughout the passing of time.

15.time period of simple pendulum depends upon the length of the pendulum, acceleration due to gravity and the temperature (as length depends on temperature).16.Horology is the study of the measurement of time. Clocks, watches, clockwork, sundials, hourglasses, clepsydras, timers, time recorders, marine chronometers, and atomic clocks are all examples of instruments used to measure time.
