Answer: The Electrostatic force of attraction or repulsion between two charges shows that the Newton's third law applies to electrostatic forces.
Explanation: Consider two Oppositely charged charges separated by distance d.
The electrostatic force exerted by charge 1 on charge 2 is.
By Coulomb's Law :
F1 = k .....................................(1)
The electrostatic force exerted by charge 2 on charge 1 is.
F2 = - k ................................. (2)
negative sign shows that force are in opposite direction.
From Equation 1 and 2
F1 = - F2
Which implies Newton Third law.

Answer:
The volume of water that was in the kettle is 1170
Explanation:
Given:
Power, P = 2.0 kW = 2000 W, Mass of stainless steel, = 710 g = 0.71 kg at temperature of
Part A:
If it takes time, t = 3.5 minutes to reach boiling point of water , then from conservation of energy,
Total energy supplied by the burner = Total heat gained by the water and the stainless steel to rise from to
i.e. Pt = (100 - 20 ) +
(100 - 20 )
=
= 1.17 kg
where = 4200 J/Kgk (specific heat capacity of water),
= 450 J/Kgk (specific heat capacity of steel)
But volume of water in the the kettle, v =
∴ v = 1170
