📡Chapter 3 : Electricity

! IMPORTANT DEFINITIONS !
Part 1

🔎E.H.T
👉🏻Extra high tension

🔍Electric field
👉🏻The REGION around a charged particle where any charge in the region will experience an electric force.

🔍Electric field strength, E
👉🏻Electric force acting on a unit postive charge placed at a point.

🔍Current, I
👉🏻The rate of flow of charge, Q in a conductor

🔍Potential difference, V
👉🏻The work done, W in moving one coulumb of charge, Q from one point to another.
V = W/Q or
V = E/Q

🔍Resistance
👉🏻Ratio between potential difference, V and current, I.
R = V/I

🔍Rheostat
👉🏻Control the current flow

🔍s.w.g.
👉🏻Size wire gauge

Part 2

🔍Resistivity of a conductor, p
👉🏻Measure of a conductor's ability to oppose the flow of the electric current.

🔍Superconductors
👉🏻Materials that conduct electricity without any resistance.

🔍Critical temperature, Tc
The temperature when the resistivity of a superconductor becomes ZERO.

🔍Electromotive force (e.m.f.)
Energy transferred or work done by an electrical source to move one coulumb of charge in a complete circuit.

🔍Voltage drop
Value of potential difference across the circuit, V is SMALLER than the e.m.f. of the dry cell
V < e.m.f.

🔍Internal resistance, r of dry cell
The resistance caused by electrolytes in the dry cell
🧠Apa effects??
😿Loss of energy in the form of heat in dry cell
😿V < e.m.f. ---- (voltage drop👀)

༊*·˚How does POLLINATION occur ?🐝🪰🌼🌬

⚡️Pollination occurs when the wall of anther is dry, and it shrinks and split
⚡️This causes pollen grain from pollen sac to release.
⚡️The pollen grain is transferred to stigma by pollinating agents such as insects, wind and animal.
⚡️The pollen grains stick to the glucose in the stigma.
⚡️The glucose molecules then stimulate the germination of pollen grains.
⚡️It will form a pollen tube.
⚡️The pollen tube grows down towards the ovule through the style.
⚡️The generative nucleus will move along the pollen tube towards the ovule and divide by mitosis to form 2 male gametes (n).
⚡️End of pollen tube secrete enzyme to digest the tissues of style.
⚡️Upon reaching embryo sac, pollen tube penetrate the ovule through micropyle.
⚡️Tube nucleus degenerate. Both male gamete enter the embryo sac.

📡Chapter 2 - Force and Motion I📡

1⃣Newton's 1st Law of Motion
👉🏻An object will remain at rest or move at uniform velocity unless acted upon by an external force

Inertia
👉🏻The tendency of an object to remain at rest or if moving, to continue its motion in a straight line at uniform velocity

2⃣Newton's 2nd Law of Motion
👉🏻The rate of change of momentum is directly proportional to the force
👉🏻Acts in the direction of the applied force
F= kma

3⃣Newton's 3rd Law of Motion
👉🏻For evert action, there is a reaction of equal magnitude, but in the opposite direction.

Impulse, J
👉🏻Change of momentum
J= mv - mu

Impulsive FORCE, F
👉🏻RATE of change of momentum
F= ( mv - mu ) / t

🔭Principle of Conservation of MOMENTUM

🧲The total momentum BEFORE collision is EQUAL to the total momentum AFTER collision if no external force is acting on it.

Basically,
Before = After
(No external force)

TIPS UJIAN LISAN BERKUMPULAN

Ni admin buat beberapa hari sebelum SPM and it worked Alhamdulillah.

Firstly, korang kena decide siapa yang kena cakap bahagian pendahuluan, isi 1, isi 2 dan kesimpulan. Kemudian untuk bahagian ke-2, korang kena discuss seorang tu nak bercakap berapa kali?

👆 Kami decide macam ni supaya semua orang adil dan boleh cakap ikut keperluan masing². Tak ada menyampuk atau potong cakap orang.

SETERUSNYA, kitaorang akan discuss situasi dalam bilik kejadian. So kitaorang akan buat beberapa rules.

1. Bincang dulu isi. Pastikan semua orang ada isi. Selagi semua orang takde isi, selagi tu lah tak boleh fikir huraian apa semua.

2. Selepas dapat isi, semua orang fikir cara hurai masing². Tak boleh tolong kawan sebab masa berbincang tu singkat. Jadi kami bincang isi je dan baki masa tu kami guna untuk fikir huraian masing². (Prioritize yourself first)

If kawan korang jenis yang cepat blur. Like masa bercakap tiba² "errrr...".. sebelum ujian lisan korang kena tanya kawan tu, "boleh tak nak menyampuk kalau kau gagap?"

Menyampuk kat sini maksudnya, korang minta izin untuk mencelah dan tanya soalan berkaitan isi kawan korang tu supaya dia boleh teruskan bercakap. Bukannya menyampuk lepastu cakap tentang isi korang.

PLEASE DON'T DO THIS ❗️

1. Potong kawan bila bercakap
2. Ambik isi orang lain
3. Buat muka pelik bila dengar huraian kawan
4. Guna bahasa inggeris

Eventhough markah secara individu, tapi kalau tak ada kerjasama dalam kumpulan, semua orang akan jatuh

“Tidaklah seseorang mandi pada hari Jumaat dan bersuci semampunya, berminyak dengan minyak, atau memakaikan minyak wangi dari rumahnya, kemudian keluar (menuju masjid), dan dia tidak memisahkan dua orang (yang sedang duduk berdampingan), kemudian dia hendak mendirikan solat yang sesuai dengan tuntutannya, lalu diam mendengarkan (dengan seksama) ketika imam berkhutbah melainkan akan diampuni (Dosa dosanya yang terjadi) antara Jumaat tersebut dan Jumaat berikutnya.” (HR. Bukhari)
