Represent each of the following units as a combination of primitive
dimensions where M=mass, L=length, T=time
Kilometer
Quart
Pascal
Watt
Newton
Horsepower
Kilometer = 1000m
Quart = 0.000946m³
Force = mass × acceleration
=> F = ma
Putting units:
Newton = kg.m/s² or kg.m.s^-2 _____(1)
Pressure = force/area
Putting units:
Pascal = Newton/m²
=> Pascal = kg.m.s^-2.m² [from (1)]
=> Pascal = kg.m^-1.s^-2
Work = force × displacement
=> W = Fs
Putting units:
Joule = Newton.m
=> Joule = kg.m.s^-2.m [from (1)]
=> Joule = kg.m².s^-2 ______(2)
Power = work/time
Putting units:
Watt = joule/s
=> Watt = kg.m².s^-2/s [from (2)]
=> Watt = kg.m².s^-3 ______(3)
Horsepower = 746 watt
=> Horsepower = 746kg.m².s^-3 [from (3)]

Explanation:
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.

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 .
The low-pressure fuel system is being discussed. Technician A says that the system must provide an adequate volume of fuel to the high-pressure fuel injection system. Technician B says that the system must provide fuel at a minimum pressure to the high-pressure fuel injection system. Which technician is correct
Answer:
Hence Both technicians A and B are correct that is Technician A says that the system must provide an adequate volume of fuel to the high-pressure fuel injection system. Technician B says that the system must provide fuel at a minimum pressure to the high-pressure fuel injection system are true.
Explanation:
The low-pressure fuel system contains the fuel filters; A fuel level sending unit/tank pick-up; A transfer pump. So from considering both technicians statements both are applicable.

8. You've been contracted to install hardwood flooring on a basketball court. The court
measures 125' x 70'. How many square feet of flooring do you need to order for the job?
Allow 20% for waste.
k
O A. 10,500 sq. ft.
O B.234 sq. ft.
O C. 100,500 sq. ft.
O. D. 8,750 sq. ft.
Answer:
our answer is d because if you multiple 125 by 70 and subtracted from 20 you Will get D.8,750 sq. ft.
Answer:
A. 10,500 sq. ft.
Explanation:
125*70 is 8750 and 20% of 8750 is 1750 so you add it and get 10,500
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.

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.
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 mathematical equation that explains the engineering relationship between inputs and outputs is called the ___________.
Answer:
Production function
Explanation:
A production function is a method of determining the difference between what goes into and what comes out of output. The formula Q = f(K, L, P, H) determines how much output you can receive from a given number of inputs. Labor (L), or individual worker input, is one of the production elements.

L / T
No dimensions
M L / T^2
M
M / (L T^2)
Answer:
M·L/T²
Explanation:
The given equation for T is presented as follows;
[tex]T = \dfrac{M \cdot V^2 \cdot A}{L^3}[/tex]
Where;
m = Mass with dimension M
V = Velocity, having the dimensions L/T
A = Area, having the dimensions L²
l = Length, having the dimensions, L
Therefore;
[tex]The \ dimensions \ of \ T = \dfrac{M \times (L/T)^2 \cdot L^2}{L^3} = \dfrac{M \times L^4/T^2 }{L^3} = M \cdot L/T^2[/tex]
