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
Answer with the given explanations below: First the given formula that looks like this is: or where:
P = power
W = work
t = time
Next with another given power formula that looks like this is:
This is the charging process of a capacitor - capacitor #1.
Then it's a very important given formula that it must also be taken into account is: which it was indicated that the voltage is proportional to the charge on a capacitor.
In the following below, from the given power formula that looks like this is: and we are considering that the current is the constant (direct current), and then the power is proportional to the voltage. If the voltage increases linearly, the power will increase the same. See the following diagram. (I'm sorry, Yhungbabe, I don't have the diagram to show you in order to refer to the total energy stored in the capacitor because I havenèt learned the energy stored in the capacitor)
Anyway, since the power varies as a function of the time, the given formula that looks like this is: cannot be applied to calculate the energy transferred. But looking at the graph, it seems that this energy can also be determined by measuring the area under the curve of the figure.
This is The Energy Stored in a Capacitor - Capacitor #2.
The area under the curve is equal to the half of the power at time "t", being multiplied by "t".
Then with the given formula below that looks like this is:
But it's known that If this is the last given formula is being replaced in the previous one, we obtain the new given formula that looks like this is: and as another new given formula that looks like this is: there's so to find out how much energy (W) that there's in a capacitor that we use in one of the new given formulas that looks like in the listed below are:
joules
joules
joules
Now finally where:
W = Work (In The Energy) in Joules
C = Capacity in the farads
V = voltage in the volts at the ends of the capacitor
Q = a capacitor charge
I apologize for the late answer and the replies, so anyway, I use the online language translator in order to translate Spanish to English for you in order to understand my work given below, so, I hope my answer with the given explanation below here is very helpful to your own question about how to calculate the total energy stored in the capacitor with the image has been provided, please mark me as Brainliest and have a great rest of the day! :D

Answer:

Explanation:
How does the force block A exerts on block B compare to the force block B exerts on block A?
Draw and label a force diagram for each block, using equality marks on the vectors.
Answers
By Newton's third law, we will see that the force that block A exerts on block B is equal in magnitude but in opposite direction than the force that block B exerts on block A.
Remember that Newton's third law says that whenever two objects interact, they exert equal and opposite forces on each other.
The force that block B exerts on block A is equal to block B's weight, which is:
[tex]W_b = 0.05kg*9.8m/s^2 = 0.49 N[/tex]
Then the force that block A exerts on block B is equal in magnitude but in opposite direction, thus it will be equal to:
F' = -0.49N
Then the diagram is the one that you can see below.

A. 450 N, yes, in the direction of the pushing
B. 0 N, no
C. 50 N, yes, in the direction of the dad

A 100g mass is attached to a string that is 75 cm long. The mass is swung in a horizontal circle that goes around once every 0.80 seconds.
What is the centripetal acceleration of the mass?
What is the tension in the string?
Answers
Answer:
Centripetal acceleration = 46.26m/s2
Tension = 4.6N
Explanation:
Centripetal acceleration is given by the following formula: [tex]a_c = \frac{v^2}{r}[/tex]
So, to calculate acceleration we first need velocity and radius.
The radius is given to us as 75cm = 0.75m, and we can find velocity from the following formula:[tex]v=r\omega[/tex] where w = the angular velocity given by: [tex]\omega = \frac{2\pi}{T}[/tex]
We are given a period of 0.80s, meaning that our angular velocity is:
[tex]\frac{2\pi}{0.80} = 7.85 rad s^{-1}[/tex]
Now we just need to multiply is by the radius to find the velocity:
[tex]0.75*7.85=5.89ms^{-1}[/tex]
Finally we square the velocity and divide by the radius to find the final centripetal acceleration: [tex]\frac{5.89^{2} }{0.75} =46.26ms^{-2}[/tex]
[tex]F=\frac{mv^{2} }{r}[/tex] so we just need to multiply the centripetal acceleration by mass to get the tension force of the string: [tex]46.26*0.1 = 4.6N[/tex]

29.92 inches of mercury and 101,325 pascals are both equivalent to 1 atmosphere of pressure. Calculate the number of pascals equivalent to 1 inch of mercury.
Answers
The number of pascal equivalent to 1 inch of mercury is 3386.53 pascal
From the question given above, we were told that:
29.92 inches of mercury = 1 atm
101325 pascal = 1 atm
Thus,
29.92 inches of mercury = 101325 pascal
With the above information, we can obtain the number of pascal equivalent to 1 inch of mercury. This can be obtained as follow:29.92 inches of mercury = 101325 pascal
Therefore,
1 inches of mercury = 101325 / 29.92
1 inches of mercury = 3386.53 pascalThus, the number of pascal equivalent to 1 inch of mercury is 3386.53 pascal

Answers
The acceleration of the car over the 2 minutes is 0.07 m/s².
Acceleration of the car
The acceleration of an object is the rate of change of velocity of the object with time.
Acceleration of the car over the 2 minutesThe acceleration of the car over the 2 minutes is calculated as follows;
a = Δv/t
a = (v - u) / t
where;
v is the final velocity = 80 km/h = 22.22 m/su is the initial velocity = 50 km/h = 13.89 m/st is the time of motion, = 2 mins = 120 sa = (22.22 - 13.89) / 120
a = 0.07 m/s²
Thus, the acceleration of the car over the 2 minutes is 0.07 m/s².

An object on Earth weighs 600 N and on Mars 100 N. If its mass on Earth is approximately 60 kg what is the mass of the object on Mars?
Answers
Answer:
I think its
10 kg
plzz plzz plzz. mark as brainliest
If the mass of an object is approximately 60 kg on earth then its mass remains the same on Mars which is 60 kg because mass does not change from place to place.
What is mass?Mass in physics is a numerical representation of inertia, a fundamental property of all matter. What a body of matter is fundamentally is the resistance it offers to a change in its speed or location brought on by the application of a force. The more mass a body has, the less of a change a force exerts results. The kilogram is the unit of mass in the International System of Units, and it is defined by Planck's constant as being equal to 6.62607015 × 10⁻³⁴ joules second (SI).
According to the question, the weight of an object depends on gravity which is different from place to place so weight also varies from place to place but the mass is constant everywhere it does not change. So, if the mass of an object is 60 kg on earth then it remains the same on mars also.
