In a hospital setting, which of the following presents the possibility of being the source of an arc flash?
Alja [10]
The answer to this question would be <span>Electrocautery Device

In a hospital, the device that can cause arc flash would be an electrocautery device or a circuit breaker. In fact, the electrocautery device is using the arc flash principle to work. The arc flash will cause burns that surgeon use to clot bleeding in surgery or to destroy a tissue.</span>

Douglas Stefanski’s spectacularly sleek hovercraft glides down a track of 36m. It takes 13 him seconds to cross the finish line.
ollegr [7]

I really don't understand what's behind this question at all,
but I can sure do the math:

           Speed = (distance covered) / (time to cover the distance) .

                      =       ( 36 meters)         /        (13 seconds)

                      =         (36/13)      (meters/second)

                      =         2.7692... meters per second  (rounded)

                                 (about   6.2  miles per hour)   .

MaRussiya [10]

The management information base (MIB) is a repository of data maintained at a managing entity site, providing the network manager with a centralized, quick-to-query database regarding current network status is considered as false

Explanation:

The management information system is a formal description set of network objects that is managed by using the Simple Network management protocol.

The performance of network is measured based on the delay throughput and packet loss. There are management information system for more related entities that are managed by the companies.

What is the magnetic force on a 200 cm length of (straight) wire carrying a current of 30 A in a region where a uniform magnetic
Bezzdna [24]

Answer:

F = 0.112 N

Explanation:

To find the magnitude of magnetic force on the wire, you use the following formula:

|\vec{F}|=|i\vec{L}\ X\ \vec{B}|=iLBsin\theta   (1)

L: length of the wire = 200cm = 0.2m

i: current in the wire = 30 A

B: magnitude of the magnetic field = 0.055 T

θ: angle between the directions of L and B = 20°

You replace the values of L, i, B and θ in the equation (1):

|\vec{F}|=(30A)(0.2m)(0.055T)sin(20\°)=0.112N

hence, the magnetic force on teh wire is 0.112N
