Answer:
Equilibrium. • When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero.
Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Physics also deals with the basic principles that explain matter and energy, and may study aspects of atomic matter by following concepts derived from the most fundamental principles. Chemistry focuses on how substances interact with each other and with energy (for example heat and light).
Answer:
Explanation:
Part A
Every force has one and only pair force , according to 3 rd law
It is true , the pair force has equal magnitude .
Part B
The two forces in each pair act in opposite directions.
It is true .
The pair forces are equal and act in opposite direction .
Part C
The two forces in each pair can either both act on the same body or they can act on different bodies.
It is false .
The two forces in each pair can not act on same body . They act on different bodies , bodies which are undergoing mutual interaction.
The answer for Plato users is C. It is the energy that is required to overcome mass defect.
From Plato "Nuclear binding energy is the energy that is required to overcome the energy that is used to keep the nucleus together, the mass defect."
