The answer to your Question is E
Answer: Because we can’t walk through walls and in this case, doors.
Explanation: no
Answer: Unstable nuclei spontaneously emit radiation in the form of particles and energy. This generally changes the number of protons and/or neutrons in the nucleus, resulting in a more stable nuclide. A nuclear reaction is a reaction that affects the nucleus of an atom.
The shear connectors must transfer axial shear stress completely. The minimum slip value is needed to limit the maximum slip at the ultimate limit state.
<h3>
What is shear connection?</h3>
A shear connection is a type of join which allows the transfer of shear forces between two members of beams or truss.
The shear connectors are used in composite beam is to transfer the longitudinal shear stresses at the interface between the steel beam and the concrete slab.
The slip requirements are less than in a propped beam. The higher strains resulting in the bare steel section carrying the construction
Thus, minimum slip value is needed to limit the maximum slip at the ultimate limit state.

Answer:
the spring coefficient is
k=16N/m
Explanation:
Hooks law states that provided the elasticity of a material is not exceeded the extension e is proportional to the applied force
Step one
Analysis of the problem
From analysis of the problem
The mass has a potential energy due to the height it was dropped from, the potential energy is then stored in the spring since it was dropped on the spring which compresses it by 0.5m
Step two
Data
Mass of object m=0.2kg
Height of building =10m
Compression of spring e=0.5m
Spring constant k=?
Step three
According to the principle of energy conservation
mgh=1/2(k*e^2)
Making k subject of formula we have
k=2mgh/e^2
Substituting our data into the expression to get k
Assuming g=9.81m/s
k=2*0.2*10/0.5^2
k=4/0.25
k=16N/m
