Answer:
The law of conservation of mass is observed in a balanced chemical equation, which is a chemical equation that shows all mass is conserved throughout the reaction. In a balanced chemical equation, the number and kinds of atoms on each side of the equation should be equal.
in this phenomenon it is denoted by
mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas mass of Liquid

Answer:
a.Systems development life cycle
Explanation:
Of all the options the correct answer is a.Systems development life cycle.
Systems development life cycle: The life cycle phases of systems development include preparation, system assessment, system design, advancement, application, inclusion and testing, as well as maintenance and support.
So, we can see that the Systems development life cycle enables staff to systematically go through every step in the development process and has a lower probability of missing important user requirements.
Answer:
B. Shear Modulus
Explanation:
In this scenario, the friction force between the sliding block and the floor causes the block to deform.
Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.
Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.
This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.
Mathematically, Shear Modulus is given by the formula;

Where;
G is the Shear Modulus.
F is the force applied to the object.
A is the area of the object.
l is the length of the object.
Dx is the change in length.
Shear Modulus is measured in Pascals.
