Answer:
is his final displacement from the point A after 60 seconds.
Explanation:
Given:
Cyclist is moving away from A.
- velocity of cyclist,

- displacement of the cyclist from point A at the time of observation,

- time after which the next observation is to be recorded,

Now as the cyclist is moving away from point A his change in displacement after the mentioned time:



<u>Now the the final displacement from point A after the mentioned time:</u>

Answer:
True.
Explanation:
A nanometer is a unit of mass, whereas a nanosecond is a unit of time. To convert 1.3 hours to minute, you would multiply by 1 h / 60 min. Kilometer is a unit of length, whereas kilogram is a unit of mass. True.
