📡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

! IMPORTANT DEFINITIONS !
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)
