Answer: C) Motion detectors
Explanation:
Motion detectors is the device that is used for detection of moving object in any area. They are used for security purposes by tracking motion or people and alerting the user.It consist of motion sensor for detection of motion and alerting the users or organization about security breach through alarming .
- According to the question,Chief information officer should implement motion detectors to investigate about theft that takes place in company's department on regular basis.Any intervention for company's loss will be alerted through tracking motion of the thief.
- Other options are incorrect because camera is used for recording videos and images. Bio-metric device is used for digital identification of any person to enter into a system. Man-trap is vestibule used for controlling access of a person for security.
- Thus, the correct option is option(C).
Answer: C. Myst because it is an adventure game
Answer:
A constructor doesn't have a return type.
The name of the constructor must be the same as the name of the class.
Unlike methods, constructors are not considered to be members of a class.
A constructor is called when a new instance of an object is created.
Explanation:
Is it multiple choice ?<span />
There two problems related to this problem:
First is the coefficient of static friction between the map
and the crate.
And the second one is at what angle does the crate begin to
slide if the mass is doubled.
1.
To look for the coefficient of static friction:
ΣF = 0
μ x m x g x cos θ = m * g * sin θ
μ = sin θ/ cos θ = tan θ
μ = tan 24 = 0.45
2.
At what angle… the solution is:
The static friction or μ does not depend
on mass, so the angle is still 24.
