258.	A : The rate of change of distance is called speed.; B:The change of distance per unit time is called as speed.; [ QUESTION: "which of the following sentence(s) is/are true. explain?; what is meant my unit time? what is the difference between the two sentences] {NOTE: WILL BE REPORTED IN CASE OF SPAMMING AND RIGHT ANSWER WILL BE AWARDED BRAINLIEST ANSWER}
Answer» <html><body><p><strong>Answer:</strong></p><p>discussed in Physical Quantities and Units, the most fundamental physical quantities are defined by how they are measured. This is the case with time. Every measurement of time <a href="https://interviewquestions.tuteehub.com/tag/involves-519086" style="font-weight:bold;" target="_blank" title="Click to know more about INVOLVES">INVOLVES</a> measuring a change in some physical quantity. It may be a number on a digital clock, a <a href="https://interviewquestions.tuteehub.com/tag/heartbeat-1016994" style="font-weight:bold;" target="_blank" title="Click to know more about HEARTBEAT">HEARTBEAT</a>, or the position of the Sun in the sky. In physics, the definition of time is simple— time is change, or the interval over which change occurs. It is impossible to know that time has passed unless something changes.</p><p></p><p>The amount of time or change is calibrated by comparison with a standard. The SI unit for time is the second, abbreviated s. We might, for example, observe that a certain pendulum makes one full swing every 0.75 s. We could then use the pendulum to measure time by counting its swings or, of course, by connecting the pendulum to a clock mechanism that registers time on a dial. This allows us to not only measure the amount of time, but also to determine a sequence of events.</p><p></p><p>How does time <a href="https://interviewquestions.tuteehub.com/tag/relate-1183023" style="font-weight:bold;" target="_blank" title="Click to know more about RELATE">RELATE</a> to <a href="https://interviewquestions.tuteehub.com/tag/motion-1104108" style="font-weight:bold;" target="_blank" title="Click to know more about MOTION">MOTION</a>? We are usually interested in elapsed time for a particular motion, such as how long it takes an airplane passenger to get from his seat to the back of the plane. To find elapsed time, we note the time at the beginning and end of the motion and subtract the two. For example, a lecture may start at 11:00 A.M. and end at 11:50 A.M., so that the elapsed time <a href="https://interviewquestions.tuteehub.com/tag/would-3285927" style="font-weight:bold;" target="_blank" title="Click to know more about WOULD">WOULD</a> be 50 min. Elapsed time Δt is the difference between the ending time and beginning time,</p></body></html>
