Answer: Energy-Isolating devices

Explanation:

Energy-isolating devices are used to restrict the flow or transmission of energy (electricity in this case) by physical means therefore it includes manually operated devices such as a manually operated electrical circuit breakers and disconnect switches.

Manually controlled circuit breakers restrict the flow of electricity if the current is too much and the flow will remain restricted until the switch is flipped back to allow electricity to flow while a Disconnect switch works by shutting down the circuit when a problem is detected.

Answer:

$T2= 406k$

Explanation:

The temperature can be defined as the measurement of the intensity of the heat present in the object. Fahrenheit, kelvin and centigrade are the common scale used for measuring Temperature.

Given:

T1=170C

To convert to Kelvin

= 17+273 =290K

T1 = 290K

Pressure (P)= 95KPa

Specific heat ratio = CP/CV= K

WhereK=1.005/0.718

K = 1.4

The final temperature can be calculated using the formula below.

T2 = CP/CV × T1

=. K × T1

T2 = 1.4 × 290

$T2= 406k$

Consider the following chain-reaction mechanism for the high-temperatureformation of nitric oxide, i.e., the Zeldovich mechanism

vagabundo [1.1K]

Answer: hello attached below is the properly written chain reaction to your question

answer :

d[NO] / dt = $k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] + K_{3f}[N][OH]$

d[N] / dt = $k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] - K_{3f}[N][OH]$

Explanation:

write out expressions for d[NO] / dt and d[N] / dt

Given :

properly written chain reaction ( attached below)

Expression for d[NO] / dt can be written as

$k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] + K_{3f}[N][OH]$

Expression for d[N] / dt can be written as

$k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] - K_{3f}[N][OH]$
