The method of social engineering that could be used to deliver ransomware is; email phishing
<h3>What are methods of Social engineering?</h3>
Ransomware is simply a type of social engineering that criminals use to steal data, infect computers, and infiltrate company networks.
Now, the most popular form of social engineering that could be used to deliver ransomware is email phishing. This is because email Phishing has become more pervasive and dangerous these days as it is used when attackers/criminals send fraudulent emails that either contain dangerous links or exploitative requests.

Answer:
67.89%
Explanation:
Energy Efficiency=
Where
is useful energy and
is the total energy
The useful energy= (19-5-1.1) million= 12.9 million
The total energy= 19 million

Therefore, the efficiency of the boiler is 67.89%

Answer:
Applied Stress > 58.29 MPa
Explanation:
- Resolved shear stress should be greater than critically resolved shear stress in order to cause the single crystal to yield
Given angles are
∅ = 42.7 degree
Ф = 48.3 degree
Critically resolved shear stress = 28.5 MPa
If we consider
Critically resolved shear stress = resolved shear stress
Applied stress can be found by
(1)
Applied Stress = 
Applied Stress = 
Applied Stress = 58.29 MPa
We got reference
- By putting applied stress values of greater than 58.29 MPa in equation 1 we get
Resolved Shear Stress = 60 x Cos(48.3) x Cos(42.7)
Resolved Shear Stress = 29.33 MPa
Therefore, by the above calculation we conclude that applied stress should be greater than 58.29 MPa, In order to make resolved shear stress to be greater than critically resolved shear stress that is essential for single crystal to yield.
