The answer to this question would be <span>Electrocautery Device

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

Answer:

B. Defibrillator

Explanation:

The electric arc occurs when there is a dielectric break in which it produces an electrical discharge. The term electric arc is the most common, but it can also be called an arc flash or short circuit as it is popularly called. This phenomenon is so strong that it can break the insulation made by air by conducting electrons from one electrode to another through a current flow.

A defibrillator is a device designed to discharge electrical charges to the chest wall (if external) or to the heart muscle fibers (if internal) of a patient with cardiac arrhythmia. Because of its ability to provide an electrical discharge, we can conclude that the defibrillator is a source of an electric arc in the hospital environment.

a DJ uses a 110-volt outlet to plug in a strobe light. if the current flowing through the light is 0.050 amps, how much resistan
tigry1 [53]

Ohms Law: V = IR

V is the voltage in volts

I is the current in amps

R is the resistance in Ohms

Rearrange: R = V/I

R = (110)/(0.050)

R = 2200

There are 2200 Ohms of resistance in the circuit.

To determine the muzzle velocity of a bullet fired from a rifle, you shoot the 2.47-g bullet into a 2.43-kg wooden block. The bl
Elza [17]

Answer:

The velocity of the bullet on leaving the gun's barrel is 236.36 m/s.

Explanation:

Given;

mass of the bullet, m₁ = 2.47 g = 0.00247 kg

mass of the wooden block, m₂ = 2.43 kg

initial velocity of the wooden block, u₂ = 0

height reached by the bullet-block system after collision = 0.295 cm = 0.00295 m

let the initial velocity of the bullet on leaving the gun's barrel = v₁

let final velocity of the bullet-wooden block system after collision = v₂

Apply the principle of conservation of linear momentum;

Total initial momentum = Total final momentum

m₁v₁ + m₂u₂ = v₂(m₁ + m₂)

0.00247v₁  + 2.43 x 0  =  v₂(2.43 + 0.00247)

0.00247v₁ = 2.4325v₂ -------(1)

The kinetic energy of the bullet-block system after collision;

K.E = ¹/₂(m₁ + m₂)v₂²

K.E = ¹/₂ (2.4325)v₂²

The potential energy of the bullet-block system after collision;

P.E = mgh

P.E = (2.4325)(9.8)(0.00295)

P.E = 0.07032

Apply the principle of conservation of mechanical energy;

K.E = P.E

¹/₂ (2.4325)v₂² = 0.07032

1.21625 v₂²  = 0.07032

v₂²  = 0.07032  / 1.21625

v₂² = 0.0578

v₂ = √0.0578

v₂ = 0.24 m/s

Substitute v₂ in equation (1), to obtain the initial velocity of the bullet;

0.00247v₁ = 2.4325v₂

0.00247v₁ = 2.4325 (0.24)

0.00247v₁ = 0.5838

v₁ = 0.5838 / 0.00247

v₁ = 236.36 m/s

Therefore, the velocity of the bullet on leaving the gun's barrel is 236.36 m/s.

Describe the interactive roles and statuses of individuals and groups in your community.
julia-pushkina [17]
In our community, every person takes a certain role in a way that they contribute something for the development of the community. Certain interactive roles include trainings, team buildings, meetings, fund raising, and etc. Every individual has also gained their own statuses depending on what they have achieved and what they have contributed as well. Those individuals that are classified in the higher statuses are those who are experienced and trained to lead. These roles and statuses help our community become better as well as helping the youth to be great models and individuals in the future.
