An alpha-numeric designator which is systematically assigned at the time of manufacture, so as to identify the manufacturer, month, year, location, and batch is referred to as lot number.

<h3>What is a product?</h3>

A product can be defined as any physical object (tangible item) that is typically produced by a manufacturer so as to satisfy and meet the demands, needs or wants of every customer. Also, some examples of a product include the following:

  • Refrigerator
  • Television
  • Microwave oven
  • Pencil
  • Smartphone
  • Computer
  • Perfume

<h3>What is lot number?</h3>

A lot number can be defined as an alpha-numeric designator which is systematically designed and assigned at the time of manufacture, so as to identify the manufacturer, month, year, location, and batch.

Consider a 1.80-m-tall man standing vertically in water and completely submerged in a pool. Determine the difference between the
defon

Answer:

17.658 kPa

Explanation:

The hydrostatic pressure of a fluid is the weight of a column of that fluid divided by the base of that column.

P = \frac{weight}{base}

Also, the weight of a column is its volume multiplied by it's density and the acceleration of gravity:

weight = \delta * v * g

Meanwhile, the volume of a column is the area of the base multiplied by the height:

V = base * h

Replacing:

P = \frac{\delta * base * h * g}{base}

The base cancels out, so:

P = \delta * h * g

The pressure depends only on the height of the fluid column, the density of the fluid and the gravity.

If you have two point at different heights (or depths in the case of objects submerged in water) each point will have its own column of fluid exerting pressure on it. Since the density of the fluid and the acceleration of gravity are the same for both points (in the case of hydrostatics density is about constant for all points, it is not the case in the atmosphere), we can write:

\Delta P = \rho * g * (h1 - h2)

We do not know at what depth the man of this problem is, but it doesn't matter, because we know the difference in height of the two points of interes (h1 - h2) = 1.8 m. So:

\Delta P = 9.81 \frac{m}{s^{2} } * 1000 \frac{kg}{m^3} * 1.8 m = 17658 Pa = 17.658 kPa

What historical event allowed both aerospace fields to make enormous strides forward?
Lostsunrise [7]

Answer:

The world wars. Especially world War II

Explanation:

The world wars were the single most notable events that led to the leap in development of the aircraft from a simple apparatus capable of flight to a sophisticated flight machine. Airplane production was at its maximum during these periods (especially world war II) and has never seen that capacity of production again since. Countries focused on research that could add even the slightest enhancements to their aircraft in order to for it to surpass that of other countries.

Dos capacitores de placas paralelas, idénticos, pero con la excepción de que uno tiene el doble de separación entre sus placas q
Charra [1.4K]

Las características de la capacitancia permiten encontrar los resultados para las diferentes preguntas

1) El capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

2) El capacitor con menor distancia tiene mayor carga

3) El capacitor con menor distancia tiene mayor densidad de carga

Los capacitores son sistema que sirve para acumular carga, esa formado por placas conductoras separadas una distancia pequeña, la capacitancia es  

             C = \frac{Q}{DV} = \frac{\epsilon_o A}{d}  

Donde Q es a carga, ΔV la diferencia de potencial, A el area y d la separación de las placas.

Busquemos las respuestas para las diferentes preguntas:

1) Cual tiene mayor campo eléctrico.

El potencial y el campo eléctrico están relacionados

            ΔV = - E d

            E = - \frac{\Delta V}{d}

Indican que un capacitor tiene el doble de separación de las placas que el otro

Capacitor 1

          E = - \frac{\Delta V}{d_1}  

Capacitor 2

         d₂ = 2 d₁  

         E₂ = - \frac{\Delta V}{2d_1}  

         E₂= ½ E₁

Por lo tanto el capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

2) Cual tiene mas carga

Busquemos la carga para cada capacitor  

           Q = ε₀ \frac{A \Delta V}{d}  

Capacitor 1

           Q₁ = (ε₀ A ΔV) \frac{1}{d_1}

Capacitor 2

           Q₂ = (ε₀ A Δv) \frac{1}{2d_1}

           

            Q₂ = Q₁/2

       

El capacitor con menor distancia tiene mayor carga

3) Cual tiene mayor densidad de energía

La densidad de energía en un capacitor esta dada por

         u_E  = ½ ε₀ E²  

calculamos para cada capacitor

           

Capacitor 1

         u_{E\  1} = ½ ε₀ E₁²

Capacitor 2

         u_{E 2} = ½ ε₀ (E₁/2)²

por lo cual el capacitor con menor distancia tiene mas densidad de carga

En conclusión con lass característica de capacitancia podemos encontrar los resultados para las diferentes preguntas

     1) El capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

    2) El capacitor con menor distancia tiene mayor carga

    3) El capacitor con menor distancia tiene mas densidad de carga

If a ball is dropped from a height its velocity will increase until it hits the ground, assuming that aerodynamic drag due to th
worty [1.4K]

Answer:

g = 9.69 m/s²

Explanation:

given,

height from where ball is dropped = 800 cm = 8 m

impact velocity = 41 ft/s = 41 × 0.3048 = 12.45 m/s

acceleration due to gravity = ?    

initial potential energy is given by

PE = m g h                          

     = m g × 8                            

     = 8 mg..............(1)

now final kinetic energy

KE= \dfrac{1}{2}m(v)^2

KE= \dfrac{1}{2}m(12.45)^2

            =77.50 m.....................(2)

comparing equation (1) to (2)

8 mg = 77.50 m

g = 77.5/8

g = 9.69 m/s²
