If you travel 30 miles somewhere and then come home again your distance is 60 miles. Your displacement is 0 because it is the ending position minus the beginning position, which are the same place (home). In other words, displacement is a vector and distance is a scalar.
The temperature at which the sample of liquid turns to gas at 135 °C is termed as boiling point.
Answer: Option A
<u>Explanation:
</u>
The observation of conversion of liquid to gas indicates that there is occurrence of change in the state of matter. The inter-conversion from one state to another can be done by either varying the temperature or by varying the pressure.
In this case, the liquid on heating gets converted to gaseous state after attaining a particular temperature say 135 °C. So, this process of conversion from liquid to gaseous state on heating is termed as boiling.
The temperature at which a liquid converts to gas is termed as the boiling point of that liquid.
Explanation:
for v vs t graph for t=9 to 11,v=15kmph
similarly v2=0,v3=60kmph&v4= -40kmph
Answer: They will NOT connect because like poles are facing each other, and like poles repel each other.
