Question

The diagram shows a circuit with a potential divider joined in series with a fixed resistor.
What are the minimum and maximum readings which can be obtained by the voltmeter?
A- 0V/ 2V
B- 0V/ 6V
C- 2V/ 4V
D- 6V/ 12V
The first value indicates min. reading while the second value indicates max. reading.

Answer 1

u hve the diagram?

Answer 2

A) is the answer, do u want me to explain?

Answer 3

Yes please?

Answer 4

If it comes to Potential divider (questions).
First of all get the proportion of the resistors, rather the ratio..in this diagram the ratio is 1:1, so the voltage supplied is divided into the ratio 1:1
1/2 * 4= 2, that is the maximum voltage that can be recieved in this proportion, minimum reading will be 0, if its nt conncted

Answer 5

Ok. Thanks a lot.

Answer 6

okay if u hve sum more jst post it..il be available thewhole night :P

Answer 7

Ok, here's the question.
An alpha particle from the source collides with a stationary particle of equal mass within a cloud chamber. Give a labelled sketch to show what the cloud chamber track looks like.

Answer 8

sketch means, ofa cloud chamber or a the perticle collision?

Answer 9

Sketch of the track.

Answer 10

Particle collision

Answer 11

ok?

Answer 12

This is how the book shows.

Answer 13

we hvnt learn anythng like this, but the alpha particle deflects back...im sure bt tht...

Answer 14

actually, if the alpha particle acts on the particle trough the nucleus (the amount of protons repel the alpha particle) but if it is 90 degrees then theres an error in the question

Answer 15

something like that i think.....
