Best way to determine the accurate/precise time for one oscillation of a pendulum???

By timing N Oscillations, and dividing the answer by N. (Where 5<N<40)

Also, we can repeat the READINGS, and calculate the average, to get even a more accurate answer.

We can use a fiducial marker, or time the oscillations from the center.

And look at an angle that allows us to see the entire motion of the pendulum, by looking perpendicularly to the direction of motion.

how to prepare home-made yoghurt?

Take sample of live yoghurt. Boil milk, cool it down, add live youghurt, place in war, place for 12-24 hours.

Thanks a ton

Fudicial, I guess?

You missed the temp. (temp should be 35-45)

Yeah

Okay final question.
Why are the celeary stalks curved when they are cut length wise with a blade? Anyone?

Guys, how do draw line graphs, like join all the points separately with a scale?

The celeary starks have a layer of epidermal cells. The epidermis prevents the cells in the stalk from expanding and a pressure acts on it from the cells. Cutting the stalk releases it's restrains. The cells expand and cause the strip to curl outwards.

Anyone?

 

[Awesome12]

Anyone?

Yes you join 2 consecutive points by a straight line

Can I get a drawn Q1 a)

I drew an eye like that, and my sir strictly criticized me. He told me to draw a circle with a dot in the middle.
Which one do I draw?

In bio we use ruled connections?Not a curve?

Well, I don't even think it matters at all.
The examiners are not our enemies, they won't penalise you for this.
I make an eye with long lashes. :')

See M/J 2004; the graph

Since it is not specified,unlike in physics,we can use both methods as can be seen from this ms statement in the june 2013 paper:
clean neat line, ruled to join plots or smooth curve through
plots;
Also in bio q's of estimation dont come so i guess its better and easier to rule the points

what is 'celeary'?

So everytime it says draw a graph u have to make ruled connections...what bout the graph of year 2001 june..plz tell me
