Physics Formulas
- Ohm's Law — V = IR.
- Power — P = VI = I²R = V²/R.
- Lens formula — 1/v - 1/u = 1/f.
- Mirror formula — 1/v + 1/u = 1/f.
- Magnification — m = v/u = h'/h.
Chemistry Key Equations
- Balancing chemical equations — law of conservation of mass.
- pH scale — acids (pH < 7), bases (pH > 7), neutral (pH = 7).
- Mole concept — Number of moles = Given mass / Molar mass.
- Key reactions — neutralisation, decomposition, displacement.
