What use do we have for motion diagrams?

Physics
1 answer:
mamaluj [8]3 years ago
7 0

Answer:

A motion diagram represents the motion of an object by displaying its location at various equally spaced times on the same diagram. Motion diagrams are a pictorial description of an object's motion. They show an object's position and velocity initially and present several spots in the center of the diagram.

Please help me Calculate the total energy stored in the capacitor​
Neko [114]

La fórmula: P = W/t  ó  W = P x t. donde:

P = potencia

W = trabajo

t = tiempo

Otra fórmula de potencia es: P= I x V

Proceso de carga de un capacitor - condensador

Una fórmula muy importante que también hay que tener en cuenta es: V = q/C que indica que el voltaje es proporcional a la carga que hay en un condensador.

De la fórmula de potencia P= I x V y considerando que la corriente es constante (corriente continua), entonces la potencia es proporcional al voltaje.  Si el voltaje aumenta en forma lineal, la potencia aumentará igual. Ver el siguiente diagrama.

Como la potencia varía en función del tiempo, no se puede aplicar la fórmula W = P x t, para calcular la energía transferida. Pero observando el gráfico, se ve que esta energía se puede determinar midiendo el área bajo la curva de la figura.

Energía Almacenada en un Condensador - Capacitor

 

El área bajo la curva es igual a la mitad de la potencia en el momento “t”, multiplicada por “t”.

Entonces: W = (P x t) / 2. Pero se sabe que P = V x I. Si se reemplaza esta última fórmula en la anterior se obtiene: W = (V x I x t) / 2, y como I x t = CV = Q, entonces para saber cuanta energía (W) hay en un condensador usamos una de las siguientes fórmulas:

W = (CV2/2) julios

W = (QV/2) julios

W  = (Q2/2C) julios

, donde:

W = Trabajo (Energía) en julios

C = Capacidad en faradios

V = voltaje en voltios en los extremos del condensador

Q = carga del condensador

What adaptation of a cheetah is shown in the image?
pychu [463]

The adaptation of a cheetah is shown in the image which shows it running is its long and strong legs to run fast which is denoted as option B.

<h3>What is Adaptation?</h3>

These are the physical and behavioral features which ensures that they survive in their changing environment.

Cheetahs are known to have long and strong legs which is the reason why it runs at a very high speed.

Kendra is a psychology student. She reads a case study about a man with schizophrenia whose symptoms include laughing for reason
soldier1979 [14.2K]

She presents symptoms of <u>disorganized schizophrenia</u> since her behavior is chaotic and is not organized around themes that are maintained over time.

<h2>What is disorganized schizophrenia?</h2>

Disorganized schizophrenia is the disease expressed through hallucinations and delusions, among the negative symptoms we find cognitive, behavioral and emotional deficits of different types.

<h3>Symptoms of disorganized schizophrenia</h3>

  • The person shows disorganization in his emotional states, in what he says and / or in his way of moving.

  • The person presents language disorganization that affects thinking and cognitive processes.

Therefore, we can conclude that the presence of inappropriate emotional expressions, disorganized language, and motivational deficits are symptoms of disorganized schizophrenia.
