explain what will happen if the series circuit is closed?
Answer:
When the circuit switch is off, no electricity will flow and then the circuit is called an open circuit. Electricity will not flow in open circuit.
Explanation:
A closed circuit has a complete path for current to flow. ... This can happen when two bare wires in a circuit touch each other. The part of the circuit bypassed by the short circuit ceases to function, and a large amount of current could start to flow. This can generate a lot of heat in the wires and cause a fire.

2225 Pa = ___________ BTU
pls answer this thank you
Answer:
2225 Pa = 2.10 BTU
Explanation:
The relationship between the Pascal and british thermal unit (BTU) is as follows :
1 pascal = 0.00094781707774915 BTU
If we want to convert 2225 Pa to BTU, we will use the above conversions.
So,
2225 Pa = 2225 ×0.00094781707774915
= 2.10 BTU
So, 2225 Pa is equal to 2.10 BTU.

Answer:
T=kg·m^2/s^2
Explanation:
T = kg (m^2/s^2) m^3 /m^3
Here I wrote down the unit for every dimension.
T=kg m^2 / s^2
m^3 is divided between m^3, this is equal to 1.
Result: T=kg·m^2/s^2

The air compressor governor controls the cut-in and cut-out of the compressor. What are the cut-in and cut-out, typically
Answer:
Air Compressor Governor
Explanation:
The governor regulates how much air is pumped into the air pumping stations by the air compressor. The governor prevents the compressors from blowing air whenever the air pressure exceeds the "cut-out" level (about 125 pounds per square inch or "psi").
The transition from 85 to 100 psi will take no more than 45 seconds. During the build-up, keep an eye on the air pressure gauge to guarantee appropriate air system performance.

The diesel fuel cooler is being discussed. Technician A says that high-pressure fuel systems generate a lot of heat. Technician B says that temperature affects the density of the diesel fuel. Which technician is correct
Answer:
Both the technicians are correct.
Explanation:
As the pressure increases the temperature will also increase in accordance with the Boyle's law hence greater amount of heat is formed.
[tex]Pressure\propto Temperature[/tex]
When the temperature increases the intermolecular spaces increase as the molecules of the fuel gain energy and their kinetic energy increases. This is limited to temperatures below dissociation/combustion temperature of diesel .
Determine the dimensions for R if R = m V / (d^2 Q) where m is a mass, V is a velocity, d is a diameter, and the dimensions of Q are M/(LT).
No dimensions
M / (L T^2)
M L / T^2
M
L / T
Answer:
No dimension
Explanation:
The given equation is [tex]R = \dfrac{m \cdot V}{d^2 \cdot Q}[/tex], where;
m = Mass
V = Velocity
d = A diameter
The dimension of mass quantity = M
The dimension of the velocity quantity = L/T
The dimension of the dimeter quantity = L
The given dimension of Q = M/(L·T)
Therefore, we get;
[tex]The \ dimension \ of \ R = \dfrac{M \times L/T}{L^2 \times (M/LT)} = \dfrac{M \times L/T}{L \times M/T} = 1[/tex]
Therefore, R has no dimensions

Herramientas para la instalación de un picaporte
Answer:
Un picaporte es una palanca en ángulo para abrir y cerrar una puerta a mano. Por lo general, el picaporte se empuja hacia abajo para abrir la puerta. El mecanismo de la cerradura de la puerta hace que el pestillo de la cerradura se salga de la placa de la cerradura mediante la rotación del pasador. No es necesario accionar el pestillo para cerrar la puerta, ya que el pestillo encaja automáticamente en su lugar.
La conexión entre las manijas de las puertas, que generalmente están unidas a ambos lados de la hoja de la puerta, se realiza mediante un pasador cuadrado. El mandril también establece la conexión con el mecanismo de la cerradura: su escuadra es guiada a través de la escuadra interior del seguidor de la manija de la cerradura, para que gire junto con ella.
Por lo tanto, las herramientas que tienen un rol en la instalación de un picaporte son, principalmente, una agujereadora para ingresar las fijaciones, destornillador y tornillos, martillo y clavos.
