Please give me all formulas of physics chapter 10 please .?

Question

Answer

Answer

The mirror formula:1/f=1/v+1/u,
magnification produced by a mirror:h'/ho=-v/u,
Snell's law:sin i/sinr=n,
lens formula:1/f=1v-1/u,
magnification produced by a lens:h'/ho=v/u,
power of lens p=1/f

Answer

1st Chapter:- Electricity.

Formulas

*The magnitude of current (I)
I = Q/t.

* Potential difference (V)
V = W/Q.

* Ohm's law
V= RI. where V is potential difference and R is electrical resistance.

*Resistance in series
Rs = R1 + R2 + R3 +...

*Resistance in parallel
1/Rp = 1/R1 + 1/R2 + 1/R3 ...

* Formula to calculate electric power
P = W/t.

Different equation of power is,
• P = W/t.
• P = VI.
• P = I²R.
• P = V²/R.

Joules law of heating
* H = I²Rt.

2nd Chapter:-Light, Reflection and Refraction.

*Mirror formula - 1/v + 1/u = 1/f.
* Magnification formula - m = h′/h (m= -v/u).

Refractive index (n) - n = Velocity of light in vaccum/Velocity of light in specific medium.

*Snell's law - Sin i /Sin r = Constant.

* Lens formula - 1/v - 1/u = 1/f.
* Magnification formula - m = h′/h (m = +v/u).

Power of lens - P = 1/f.

Hope it will be useful to you friend.

Answer

Formulas of Physics Chapter 10

Electricity

Electric current (I) = Q/t

Ohm's law: V=IR

Resistance (R) = V/I

Power (P) = IV

Energy (E) = Pt

Electric potential (V) = W/Q

Electric field (E) = F/Q

Capacitance (C) = Q/V

Energy stored in a capacitor (U) = 1/2CV²

Electromagnetism

Magnetic force (F) = qvBsinθ

Magnetic field (B) = F/qv sinθ

Magnetic flux (Φ) = BAcosθ

Faraday's law of electromagnetic induction: E = -dΦ/dt

Lenz's law: The induced current in a circuit always flows in a direction so as to oppose the change that produced it.

Transformer equation: V₁/V₂ = N₁/N₂

Optics

Speed of light (c) = 3 x 10⁸ m/s

Index of refraction (n) = c/v

Snell's law: n₁sinθ₁ = n₂sinθ₂

Thin lens equation: 1/f = 1/do + 1/di

Conclusion

These formulas are essential for understanding and solving problems in physics chapter 10. Each formula has its significance and usage in different scenarios. Proper understanding and application of these formulas will help the students achieve good grades in the subject.
