Korean Songs, eh.

I know the title is irrelevant. HEEEE.
Okay girls. For tomorrow WEDNESDAY, TENTH OF FEBRUARY, we need to get these done.

Biology - PEKA(overdue!) and worksheets?

Physics - Exercise 1.
Lens Equation

1. The magnification of a convex lens is 4. An image is formed at a distance of 20cm behind the lens. Find the object distance.
2. The magnification of a convex lens is 2. Calculate the distance between the object and the image if the object distance is 8cm.
3. The focal length of a convex lens is 10cm and an inverted image is formed if the size of the image is twice the size of object. Calculate the distance between the image and the object.
4. The focal length of a concave lens is 10cm. A 4cm tall object is put 6cm in front of the lens. Calculate the height of the image formed.
5. An object is 12cm in front of the convex lens and the image is formed is at infinity. If the object is places 8cm in front of the lens, what is the characteristics of the image formed?

BM -  Bring tatabahasa book, to hantar or whatever. Karangan I'm not sure when she said we have to hand it in (did she even tell us when?)

English - For those in 5SB, nothing, I think. She didn't tell us if we need to hand in our essay books.

Maths - Website report(by this Friday) and PATS.

AddMaths - Book 2. (I know tomorrow tak ada, but just finish up the work in book 2 and bring it to school.)

Chemistry - Hand in PEKA! All of them. Finish the exercise: Task 1.8, the carbon compound of alkanes, and that substitution method thing (the one we have to do step by step tuu).
