Class 10 Physics
Light
- Mirror formula: 1/f = 1/v + 1/u
- Lens formula: 1/f = 1/v - 1/u
- Magnification: m = -v/u
- Power of lens: P = 1/f
Electricity and Magnetism
- Current: I = Q/t
- Potential difference: V = W/Q
- Ohm's law: V = IR
- Power: P = VI = I^2R = V^2/R
- Energy: E = Pt
- Force on conductor: F = BIL
Class 10 Chemistry
Reactions, Acids and Carbon
- Conservation of mass: Total mass of reactants = total mass of products
- pH: pH = -log[H+]
- Neutralization: acid + base -> salt + water
- Density: mass / volume
- Alkanes: CnH2n+2
Class 10 Biology
Life Processes and Heredity
- Photosynthesis: 6CO2 + 6H2O -> C6H12O6 + 6O2
- Aerobic respiration: C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy
- Monohybrid ratio: 3:1
- Dihybrid ratio: 9:3:3:1
