Answer:
if I am correct, they indicate less steep terrain. think of it as the steeper the terrain the closer together the lines would be. hope that makes sense for you guys.
Answer:
A. False, frequency can increase or decrease wavelength.
For example: a high frequency would mean there are shorter wavelengths that occur in a period. Meanwhile, a low frequency would indicate that the wavelengths are longer and in longer periods.
A, it's more about the force with leverage.
Explanation:
<em>"The accuracy of a potentiometer can be increased by decreasing the potential gradient across the potentiometer wire, and this can be achieved by increasing the length"</em>
<em />
<u>The factors that are affecting/limiting the accuracy of the potentiometer are:
</u>
-
The specific resistance of the material of the potentiometer wire.
- The potential gradient
- The current passing through the potentiometer wire.
- Area of a cross-section of the wire
- Internal temperature.
<u>The objective of reversing the terminals of the cell</u>
If the jockey of the potentiometer is pressed for a long time, joule heating sets in, so that reversing the terminals of the potentiometer will prevent the resistance due to joule heat from being added to the measured resistance, ultimately preventing unwanted resistance
