There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.
Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.
The distance between the two points is always positive because the direction does not matter.
However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.
In other words:
<em>Speed </em>is looking at the <em>magnitude</em>
<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.
Welp you have to show the model...
The circulation of blood refers to its continual flow from the heart, through branching arteries, to reach and traverse the microscopic vessels in all parts of the body, reconverging in the veins and returning to the heart, to flow thence through the lungs and back to the heart to start the circuit.
