can a question on radioactivity come in atp
plz reply..................

It comes very rarely, i saw it only once from 2006 to 2013.
And CRO too, only once.

Lenses, light, Forces, Measurements, Mass-Weight-Density, are the most common topics.

heyyy when's a graph inversely prop?

heyyy when's a graph inversely prop?

When x increases and y decreases and vice versa

 

[Maganius]

When one value is increasing while the other one increasing then we say that they are inversely proportional.

 

[Maganius]

Anyone there?

How can I know if I'm supposed to draw a straight line graph or a smooth cure for physics?

When the points are linear and in a straight line
Or when they are directly proportional

Both cases, I guess :/

increasing at both times? :O

2nd one.

2nd one is correct.

 

[Maganius]

when's a graph inversely prop?

When there's a curve on the graph 'cause when values are directly prop. we get a straight line

aray wts the relation that u said increasng dcreasng thingy?

Guys..i want to know uptill what value of significant numbers should we round in atp?and is it cumpolsory to draw a triangle to measure the gradient of a line can we measure it directly?
Plz reply fast..thanks

3 sf.and yes we have to draw triangle to specify.
