The value of the normal force exerted on a 2,000 gram block on a table
kobusy [5.1K]

Answer:

N = 19.6 N

Explanation:

Given that,

Mass of a block, m = 2000 g

1 kg = 1000 g

It means, 2000 g = 2kg

We need to find the value of normal force on the block on a table. Normal force is balanced by the weight of the block as follows :

N = mg, g is acceleration due to gravity

N = 2 kg × 9.8 m/s²

N = 19.6 N

So, the normal force acting on the block is 19.6 N.

what factors limit the accuracy of a potentiometer and what was the objective of reversing the terminals of the cell​
cricket20 [7]

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>

  1. The specific resistance of the material of the potentiometer wire.
  2. The potential gradient
  3. The current passing through the potentiometer wire.
  4. Area of a cross-section of the wire
  5. 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
