做咩係度覆我既上左岸讀返phy 要孖星應該唔係太難姐

E2 A C B C A A B D
2.4
En = -13.6 z²/n² (z is the atomic number)
E3
B A D D A B D A
3.4
End use energy efficiency
應該係對比返由mining(primary source)時
咁transmit會有energy loss
都係其中既原因

條實驗題 可唔可以講試多幾次拿多啲data 去搵average 然後攞返個 accurate result 
應該唔可以，呢個唔係adjustment to experimental setting
當儲圖鑑咁玩
同埋見工個陣多把刀咁囉
雖然5**教低form physics應該係大材小用

印象中好少日校會比同一個老師教兩科dse
通常我聽得最多係 教dse elective+低form數/通識
希望條題目得一分
應該係
treatment of data 1M+1A
one adjustment 1A

巴打可摸耳做埋e1
#791
3ci 唔係5.28 years?
E1
1a 163000 yrs ago
1b smaller than 2.9 because the distance of the supernova from the Earth is further than 10pc
1ci 20.8Rs
1cii region A ，No because its surface temperature is very high，it does not look red in color
1d Q：L0 because it does not show doppler shift
P：L2 because it is approaching to the observer，so it shows a blue shift

手多打左point P，唔洗理

除咗最後RED/BLUE shift唔記得, 其他都同巴打一樣
得返20層要搵人開新post
