They all finish exactly where they start.

Only if your entire walk is in the same straight line. Otherwise, no.Example:Start anywhere on the track at the high-school football field, and walk all the way around it.The distance you walk is 1/4 mile. Your displacement is zero, because you're now standingexactly where you began.
The distance and displacement are the same when the displacement is parallel to itself or straight. Displacement is a vector and distance is a real number or scalar. If an object is displaced around a circle the displacement is zero and the distance is 2pi r.
All molecular motion stops at absolute zero. This would not stop the passage of time.
The most significant thing about the temperature of absolute zero is that is marks the point where molecular motion stops. It is equal to −459.67 degrees Fahrenheit.
A net force of zero means that an object behaves as if there are no forces acting upon it, although this may not be the case. Usually objects have many forces acting upon them. Just your computer that is sitting on your desk is experiencing a force of gravity, the force from the table pushing up on the computer, a frictional force holding the computer in place, etc. We can add the effects of these forces to determine one force that produces the same effect as every force that acts upon the object. This is called the principle of superpostion, which states that every force can be added to other forces to find a single net force. In the case of the computer, the force of gravity is cancelled out by the force of the table pushing up on the computer. So far we have zero force. The force of friction will resist any force that you exert upon the computer, so that force is also zero. As long as your computer is at rest and not sliding across the table, it is experiencing zero net force, while there are really many forces acting upon it.
If what you want to do is calculate the work, you need to multiply the force times the displacement.
When the velocity is zero at the crossing of the time axis, the displacement must be a full maximum or minimum. Scroll down to related links and look at "Displacement - Velocity- Acceleration".
An object with no movement at all has a zero speed or which have an constant speed. 0
They are both dwarf planets first of all, another thing is that their orbit paths are not cleared.
All reactive metals undergo a similar single-displacement reaction with water. They all form hydrogen.
Not true. If the graph starts with displacement = 0 when time = 0 then it must return to zero at time = half the period, and all multiples of that value. If the graph starts at some other value, it must return to zero within t = half the period, and then keep returning to zero after every half-period.
Then the resistance is greater than the applied force. It happens all the time - like if you hit your head against a brick wall!
Sure. If the motion is all in a straight line, then the distance and displacement are equal. ==> The Olympic 100-meter sprint is in a straight line. Distance = Displacement = 100 meters. If the direction of motion ever changes, then the distance and displacement are not equal. (I think if the direction of motion ever changes, then the distance has to be greater than the displacement.) ==> In the Indianapolis 500, Distance = 500 miles, Displacement = Zero, because the Starting line and Finish line are in the same place, so the car finishes at the same place he started at.
The plural possessive for the noun path is paths'. Example: All of the paths' surfaces were either rough or muddy.
There are 6 series paths that are used to connnect all of the devices.
Displacement is the distance between the starting point and the end point. If you drive your car to the office in the morning and drive it home again at night, the odometer shows a gain of, say, 15 miles, even though the displacement is zero ... the car ended up exactly where it started. Even a better example: If you drove your car back to the dealer's showroom where you picked it up 5 years ago, the displacement for that 5 years would be zero, although the odometer reads 100,000 miles. The odometer displays the distance the car moves, and adds another inch every time the car moves an inch. Distance and displacement have the same magnitude only over a period of time when the travel was all in a straight line, with no turns or curves.
yes.only positive displacement pumps can be used in hydraulics
