Guidelines for magnification and drawing a large diagram; anyone?

Take all lengths in mm. Before making the drawing, measure the length and width of the image, suppose it's 30mm, make it approx. 60 in your drawing. You may draw a line of symmetry and then draw, easier way fore people who are not good at drawing like me. Don't shade anything, label clearly. That's it.

You are gonna have a bad time.
My dad says math is the mother of all subjects.

I'm not even going to ever touch a Maths book once I'm done with O'levels. I hate it no matter what. Worst subject.

We also have to enter final magnification if the image is already magnified e.g it is magnified X2000 and we make a drawing 1.5 times that so we will write x3000 in the end for our magnification

You mean drawing length/image length*magnifiaction?

Yuss Yuss i wanted to explain to you in non-mathematical lingo,seeing your immense love for the subject : P

How can we keep the temperature of the wire constant in a circuit.?

Maths is father*
and my teacher says,
"jographee, is the mother uf, aal subjects"

whatever but
Bio is @#$%@^of all subjects

Set up cooling like water bath or water jacket

put ink on ball, it leaves a mark on the floor

cooloing jacket around the wire? R u sure?

 

[Faizan Muhammmad]

the wire will be insulated ofcourse
other than that I have no idea

Place it in a water bath and measure temperature..And yes it is safe.We can also place in oil and keep temperature constant.The wire will obviously not be bare

Can someone please explain.. Question 1 part a(ii), (iii), f... and 3(c).

(a) i That much of accuracy is not required as the rest of the values have also been calculated to only 2 decimal places
(a) ii One student drops the cup from a height above the ground, giving a signal when he releases it, and the other times it

(f) Due to the weight increasing, the effect of air resistance is decreasing

(3) c The test tube is being heated for 15 min, and we are measuring temp change for 20 min. So just draw a graph that shows temp increase to 90 and then decrease to room temp.
