The quantity can be work or kinetic energy or potential energy. Work is same as the energy.
Work done can be described as energy transferred from and object when a force is applied along a displacement. That is work done is the product of force in the direction of the displacement and the magnitude of the displacement.
Mathematically it can be represented as,
W = F x d
where,
W ⇒ work done
F ⇒ force acting along the displacement
d ⇒ magnitude of displacement
We know,
force = mass x acceleration
∴ the unit of force is kgms⁻²
The unit of work done will be kgms⁻² x m
That is kgm²s⁻²
where m is the unit of displacement that is meter (m)
Hence kgm²s⁻² is the unit for work or energy

<span>Right-hand rule reveals a connection between the current and the magnetic field lines in the magnetic field. It is also called Ampere`s right hand screw rule. It determines the direction of the magnetic field surrounding a current carrying wire. The thunb points direction of current and fingers point the direction of magnetic lines of force.

Answer:
The object will sink in the liquid in beaker 1.
The object will float in the liquid in beaker 2
Explanation:
The density of an object relative to the density of a fluid determines if the object floats or sink in a fluid. The density of a material is the measure of the amount of mass of that material packed into a unit volume of that material.
For the beaker 1, the liquid in this beaker has a density of 0.5 g/cc, which is lesser than the density of the object (0.85 g/cc). This means that the object will add more mass than there should be to the volume of the space it displaces within the field. This results in the object sinking in the fluid.
For beaker 2, the liquid in this beaker has a density of 1 g/cc, which is more than the density of the object (0.85 g/cc). This means that the object will add less mass than there should be to the volume of the space it displaces within the field. This results in the object floating in the fluid.
