Answer: Work done by the box will be 8 Joules.
Explanation:
Work done by a substance is the product of the force applied on it and the displacement of a substance.
Mathematically,

Where,
W = work done = ? J
F = Force applied = 4 N
s = displacement = 2 m
Putting values in above equation, we get:

Hence, work done by the box will be 8 Joules.
Answer:
the buoyant force acting on the ice cube is 0.119 N
Explanation:
given,
volume of ice cube = 15 cm³ = 15 × 10⁻⁶ m³
density of ice cube = 917 kg/m³
density of ethyl alcohol = 811 kg/m³
buoyant force = ?
The density of ice is more than ethyl alcohol hence it will sink.
buoyant force acting on the ice cube = ρ V g
= 811 × 15 × 10⁻⁶ × 9.81
=0.119 N
so, the buoyant force acting on the ice cube is 0.119 N
Over time, the substances will reach equilibrium, meaning the heat calories lost by Substance 1 will be gained by Substance 2. Therefore, Substance 2 will eventually gain 40 calories of heat.
