The displacement of a moving object is the straight-line distance between the place it starts from and the place where it stops.
The displacement of anything moving along a circular track depends on how far around it goes before it stops. The greatest displacement it can possibly have is the diameter of the track ... 100m on this particular one ... because that's as far apart as two places on a circle can ever be.
The most interesting case is when the object goes around the circle exactly once. Then it stops at the same place it started from, the distance between the starting point and ending point is zero, and after all that motion, the displacement is zero.
Answer:
Ptolemy proposed a model, he reference system is centered on the Earth
Copernicus, proposed a deferent system, this system is centered on the Sun, where it is at the origin of the system
Explanation:
Thousands of years ago, Ptolemy proposed a model to explain the movement of the planets and stars in the sky, in this model the reference system is centered on the Earth, so each body is orbiting in different spheres around the Earth as its center, this system had very complicated calculations and curves to be able to explain the orbits of the planets.
More recently Copernicus, proposed a deferent system, this system is centered on the Sun, where it is at the origin of the system, in this system the movement of the planets are ellipses, which is a much simpler explanation and has been widely accepted, in current systems the reference system is fixed in the bodies more massive, since this simplifies the explanation of the movements.
The power train is a vehicle's consists of components that generate and transmit power to the wheels.
<h3>What do you mean by power train?</h3>
The collection of all the parts that propel your car forward is called the powertrain. The engine of your car generates power, which the powertrain then transfers to the wheels on the ground. The engine, transmission, driveshaft, axles, and differential are the main parts of a powertrain. A high-performance sports sedan is frequently described as having smooth steering, acceleration, and braking, as well as great body control and improved driving safety. These methods are crucial, but they are not the "end-all" of a great sports car. Its incredible performance figures, such as its ability to accelerate from zero to one hundred kilometers per hour in just seconds, come exclusively from your powertrain.
