In a certain circuit the number of electrons passing a given point in 3 seconds is 6 x 1014 electrons. What is the current flow in this circuit? (Show all work, including substitution with units)
Answer:
Current = 0.000032 Amperes
Explanation:
Given the following data;
Time, t = 3 seconds
Number of electrons = 6 * 10^14 electrons
Conversion:
First of all, we would convert the number of electrons to charge.
Coulombs = electron charge ÷ 6.2415 * 10^18
Coulombs = (6 * 10^14) ÷ (6.2415 * 10^18)
Coulombs = 0.000096 Coulombs
To find the current;
Mathematically, quantity of charge is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
0.000096 = current * 3
[tex] Current = \frac {0.000096}{3} [/tex]
Current = 0.000032 Amperes

.- Una esfera hueca de acero a 28°C tiene un volumen de 0.4 m³, calcular a) ¿qué volumen final tendrá a -6°C en m³ y en litros? B) ¿Cuánto disminuyó su volumen en litros?
Answer:
Ve respuesta abajo.
Explanation:
Para hacer esto, podemos asumir que la presión es constante, pues es un proceso adiabatico, por tanto se aplica la ley de Charles a presión constante:
V₁/T₁ = V₂/T₂ (1)
De ahí podemos despejar V₂, ya que conocemos las condiciones iniciales de temperatura y volúmen, y la temperatura final:
V₂ = V₁ T₂ / T₁ (2)
Las temperaturas deben estar en grados Kelvin, y solo es cuestión de sumarle 273 al valor de la temperatura dada en °C:
T₁ = 28 + 273 = 301 K
T₂ = -6 + 273 = 267 K
El volúmen podemos pasarlo a litros ahora o al final. En este caso, podemos dejarlo en m³ como está y luego pasarlo a Litros. Resolviendo tenemos:
V₂ = 0.4 * 267 / 301
V₂ = 0.35482 m³Pasando este volumen a Litros, sabiendo que 1 m³ son 1000 L:
V₂ = 0.35482 * 1000
V₂ = 354.82 LFinalmente para saber cuanto disminuyó el volumen en Litros, pasemos el volumen inicial a Litros y luego se hace la resta con el volumen final:
V₁ = 0.4 * 1000 = 400 L
V₁ - V₂ = 400 - 354.82
V₁ - V₂ = 45.18 LEsto es lo que disminuyó. Espero te ayude.

What happens when you burn a piece of wood in a campfire?
Energy is released due to friction.
Solar energy is released.
Nuclear energy is released.
Chemical energy is released.
Answer:
In the case of burning wood, stored potential energy (in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in the form of heat

Explanation:
the total resistance of the circuit
The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Answer: 3
Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Two parallel plates of area 7.34 x 10^-4 m^2 have 5.83 x 10^-8 C of charge placed on them. A 6.62 x 10^-6 C charge q1 is placed between the plates. What is the magnitude of the electric force on q1? Hint: How is force related to the field? (Unit = N)
Answer:
* if the two plates have the same charge sign F_net = 0
*if one plate is positive and the other is negative F_net = 59.4 N
Explanation:
The electric field created by a parallel plate is
E = [tex]\frac { \sigma }{2 \epsilon_o }[/tex]
where sigma is the charge density
σ = Q / A
we substitute
E = [tex]\frac{Q}{A \ 2 \epsilon_o }[/tex]
E = [tex]\frac{ 5.83 \ 10^{-8} }{7.34 \ 10^{-4}\ 2 \ 8.5 \ 10^{-12} }[/tex]
E = 4.487 10⁶ N / C
the electric force is
F = E / q
in this force it is a vector, so if the charges are of the same sign they repel and if they are of the opposite sign they attract. In this case, the test load is between the two plates that have the same load sign, so the forces are in the opposite direction.
* if the two plates have the same charge sign
F_net = F₁ - F₂
F_net = q (E₁ -E₂)
since the electric field does not depend on the distance
E₁ = E₂
in consecuense
F_net = 0
In a more interesting case
*if one plate is positive and the other is negative
F_net = F₁ + F₂
F_net = q (E₁ + E₂) = 2 q E₁
F_net = 2 6.62 10⁻⁶ 4.487 10⁶
F_net = 59.4 N
net force goes from positive to negative plate

In a nuclear power plant, uranium atoms ______
A. Combine and give off heat energy
B. Split and give of heat energy
C. Burn and give of heat energy
D. Split and give off electrons
Answer:
All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.

i want to now why volcanoes erupt
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Explanation:
Explanation:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

The edge effect in habitats are caused by:
A. habitat fragmentation
B. biological magnification
C. eutrophication
D. destruction of habitat
The edge effect in habitats is caused by habitat fragmentation. Therefore, option A is correct.
Habitat fragmentation refers to the process by which large, continuous habitats are divided into smaller, isolated fragments due to human activities or natural events. It occurs when natural landscapes are altered or disrupted. It results in the fragmentation of once-continuous habitats into smaller patches.
This fragmentation can happen through various means, such as the construction of roads, urban development, agriculture, deforestation, or natural events like wildfires or floods.
