Question

An ant (A) and a snail (B) went on a running race. Their distance-time graphs are shown above. Who is faster? Justify your answer​

Answer 1

Answer:

In distance time graph to find the which Vehicle is moving faster.

We know that faster vehicle will more distance in same time, So we will draw line at parallel to distance axis at particular time. Curve line which cut at the top of the line, will have more velocity. it have more displacement in that same interval of time.

Answer 2

$Time</p><p></p><p>As discussed in Physical Quantities and Units, the most fundamental physical quantities are defined by how they are measured. This is the case with time. Every measurement of time involves measuring a change in some physical quantity. It may be a number on a digital clock, a heartbeat, or the position of the Sun in the sky. In physics, the definition of time is simple— time is change, or the interval over which change occurs. It is impossible to know that time has passed unless something changes.</p><p></p><p>The amount of time or change is calibrated by comparison with a standard. The SI unit for time is the second, abbreviated s. We might, for example, observe that a certain pendulum makes one full swing every 0.75 s. We could then use the pendulum to measure time by counting its swings or, of course, by connecting the pendulum to a clock mechanism that registers time on a dial. This allows us to not only measure the amount of time, but also to determine a sequence of events. \</p><p></p><p>$
