Some important and basic points:
Unit of time is second (s).
Unit of mass is kilogram (kg).
Unit of distance/displacement is meter (m).
P.S. Displacement and distance are nearly same things, their unit is same.
Speed/velocity = distance/time
So, its unit is m/s.
Acceleration = (final velocity-initial velocity)/time.
So, its unit is m/s² or m.s^-2
We know from the formula that,
Force = mass × acceleration
=> F = ma
Putting units:
Newton = kg.m/s² or kg.m.s^-2 _____(1)
Putting dimensions:
Newton = M.L.T^-2
________________________
We know from the formula that,
Work = force × displacement
=> W = Fs
Putting units:
Joule = Newton.m
=> Joule = kg.m.s^-2.m [from (1)]
=> Joule = kg.m².s^-2 ______(2)
Putting dimensions:
Joule = M.L².T^-2
________________________
We know from the formula that,
Power = work/time
Putting units:
Watt = joule/s
=> Watt = kg.m².s^-2/s [from (2)]
=> Watt = kg.m².s^-3 ______(3)
Putting dimensions:
Watt = M.L².T^-3
________________________
We know from the formula that,
Horsepower = 746 watt
=> Horsepower = 746kg.m².s^-3 [from (3)]
Putting dimensions:
Horsepower = 746M.L².T^-3
Hope it helps!!The dimension of Watt, Newton and horsepower are ML²T⁻³, MLT⁻² and ML²T⁻³ respectively
Units and dimensionUnits are measure of a quantity. Dimensions are derived from the units. Gi
Force = mass × acceleration
For Newton:
Another representation for unit of Newton is kg.m/s². Writing in terms of the dimension
Newton = MLT⁻²
For Watts;
The unit of Watt is also kg.m².s⁻²/s which is equivalent to kg.m².s⁻³
In terms of dimension
Dimension of Watt = ML²T⁻³
For Horse power:
The unit of horse power is kg.m².s⁻³
Dimension of horsepower = ML²T⁻³

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.

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 T if T = M V^2 A / L^3 where M is a mass, V is a velocity, A is an area, and L is a length.
L / T
No dimensions
M L / T^2
M
M / (L T^2)
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
PD: I'm not sure if this is what you ask for. I hope it helps

Determine the dimensions for T if T = M V^2 A / L^3 where M is a mass, V is a velocity, A is an area, and L is a length.
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]
