How about the indicator question ? How to do that ? I got C but apparently its D

I thought the Cl have more priority over F since the alphabetical order. So I put D.

one year not playing LoL. can't wait

I am confused as to whether other oxides of nitrogen and sulfur is also present int the Antarctic ice-core drilling's findings. I thought only carbon dioxide was involved. Some sample answers related this to oxides of nitrogen and sulfur. I am confused. Can anyone clarify whether oxides of N and...

Has anyone ever got 100 for physics or any science subjects ?

process information from secondary sources to summarise the processes involved in the industrial production of ethanol from sugar cane.

I got the same. I used v^2 = u^2 +2as and then use pythagoras.

White dwarfs have a solar mass of less than 1.4 (Chandrasekar Limit). This means that the electron degeneracy pressure can hold back its gravitational collapse, causing it to be more denser and no longer undergoes fusion reaction. Correct me if I am wrong.

When a newly formed protostar acquires an equilibrium such that its gravitational collapse is balanced by an outward pressure from the heat by its core. The protostar then accretes more material from the cloud surrounding it which then blows off the rest to reveal itself which was previously...

Prediction for an 8/7 marker ?

Thank you. I checked the marking guidelines now and they seem to have a reference to horizontal component of the velocity. Can you have a look at that too? Thanks again.

That's how I done it, but the sample answers uses somehow horizontal component of the velocity and their answer is 2.9x10^-8 seconds.

This is from 2009. I don't get it why they use horizontal component instead of vertical. Can someone explain part b ?

A 1.0 W beam of light transfers 1.0 J per second from one point to another. With reference to the particle model of light, contrast a 1.0 W beam of red light and a 1.0 W beam of blue light. 2 marks (2011)

This image is good.
