At the end of one full time period, the ant has returned to where it was at the beginning of the time period. Its displacement is <em>zero</em>.
I think atoms and molecules in matter are always in motion because of kinetic energy.
Answer:
Time = 80.91 seconds
Explanation:
Given the following data;
Velocity = 5.50 m/s.
Distance = 445 meters
To find the time;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;

Substituting into the formula, we have;
5.5 = 445/time
Time = 445/5.5
Time = 80.91 seconds
Answer:
Explained below.
Explanation:
Yes cars have antennas.
Now there could be an antenna for listening to radio stations which could be regular radio stations or even satellite radio stations.
Also, there could be antennas used for GPS navigation or some form of communication with other vehicles that possess that type of antenna.
