If we use to construct the latches on the windows and doors, then the magnetism will keep thee latches secure.
Daniel [21]

Answer:

<em>a. True</em>

<em></em>

Explanation:

I'll assume the question is about magnetic latches and locks.

Magnetic door locks use an electromagnetic force to stop doors from opening, so they are ideal for security. There are two main types of electric locking devices. Locking devices can either be a fail-secure locking device that remains locked when power is lost, or a fail-safe locking device that is unlocked when de-energized. An electromagnetic lock creates a magnetic field when energized or powered up, this causes an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening.

5. Principal Rodriguez has asked all students exit the building by 2:45 pm! If you want to exit
Kryger [21]

With the Pythagoras Theorem we can find that the distance traveled is:

      39 m

The distance is the length of the path between two points and it is a scalar magnitude so if the path changes direction the Pythagorean theorem should be used

               d = \sqrt{(x-x_o)^2 + (y-y_o)^2 + (z-z_o)^2 }

Where d is the distance, (x,y,z) is the interes point, (x₀,y₀,z₀) is de reference point.

In this case, let's set a reference system in the lower part of the school, take the z-axis as vertical and set the point of arrival at as the reference (0, 0, 0).

The distance that the students descend is d₁ = 30 k ^ m, when they arrive from the bottom of the school they travel d₂ = 15 j ^ m and d₃ = 20 i ^ m

let's calculate

              d =\sqrt{(20-0)^2 + (15-0)^2 + ( 30-0)^2 }  

              d = 39.05 m

Notice that the distance by being a scalar does not have unit vectors

In conclusion using the Pythagoras Theorem we can find that the distance traveled is 39 m

Describe the relationship between the direction of the velocity vector and the direction of the acceleration or a body moving in
Law Incorporation [45]

In the centripetal movement, what happens with velocity is that it will remain constant, always pointing in its tangential direction of the trajectory. Said speed, although constant, will have a constant direction that will generate an acceleration that will always point towards the center of the circle radius. Both vectors as the turn is performed will always be perpendicular to each other.
