how many electrons does a neutral atom of the element oxygen have?
Answer:
8 electrons
Explanation:
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.

Answer:
I. 90%
II. 60 MW
Explanation:
From the question given above, the following data were obtained:
Power input = 600 MW
Power output = 540 MW
I. Determination of the efficiency.
Power input = 600 MW
Power output = 540 MW
Efficiency =?
Efficiency = output / input × 100
Efficiency = 540 / 600 × 100
Efficiency = 90%
II. Determination of the power wasted by the pump.
Power input = 600 MW
Power output = 540 MW
Power wasted =?
Power wasted = Power input – Power output
Power wasted = 600 – 540
Power wasted = 60 MW

A una temperatura de 329°K una placa de aluminio tiene un área de 15 m2, si su temperatura disminuye hasta 288°K; ¿Cuál es el valor de su área final?
Answer:
El área final de la placa de aluminio es 14.971 metros cuadrados.
Explanation:
Para pequeñas deformaciones, la expresión para la dilatación de área es la siguiente:
[tex]A_{f} = A_{o} \cdot [1+2\cdot \alpha \cdot (T_{f}-T_{o})][/tex] (1)
Donde:
[tex]A_{o}[/tex], [tex]A_{f}[/tex] - Áreas inicial y final de la placa, medidas en metros cuadrados.
[tex]\alpha[/tex] - Coeficiente de expansión lineal, medido en [tex]\frac{1}{K}[/tex].
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Temperaturas inicial y final de la placa, medidas en Kelvin.
Si sabemos que [tex]A_{o} = 15\,m^{2}[/tex], [tex]\alpha = 23\times 10^{-6}\,\frac{1}{K}[/tex], [tex]T_{o} = 329\,K[/tex] y [tex]T_{f} = 288\,K[/tex], entonces el área final de la placa es:
[tex]A_{f} = (15\,m^{2})\cdot \left[1+2\cdot \left(23\times 10^{-6}\,\frac{1}{K} \right)\cdot (288\,K-329\,K)\right][/tex]
[tex]A_{f} = 14.971\,m^{2}[/tex]
El área final de la placa de aluminio es 14.971 metros cuadrados.

Please write ONE complete sentence describing the relationship between Kinetic Energy and Gravitational Potential Energy in a system
where energy is conserved:
Answer:
Explanation:
The sum of kinetic and potential energy is the mechanical energy of the system. Assuming the energy of the system is conserved, which it is in your case, then the initial mechanical energy will equal the final mechanical energy. This relationship is very useful in mechanics.

The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
A. The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
B. The gravitational potential energy decreases and the kinetic energy increases.As soon as the ball starts moving it no longer has gravitational potential energy; it has only kinetic energy.
C. The kinetic energy and and gravitational potential energy both decrease. Both forms of energy are used up as the ball moves and are not transformed into any other form of energy.
D. The gravitational potential energy and the kinetic energy both stay the same. One form of energy cannot be transformed into a different form of energy.
Answer:
The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
Explanation:
The gravitational potential energy is the energy due to the position of a body above the ground.
Kinetic energy is the energy due to the motion of a body.
From the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
As the ball rolls down the ramp, the potential energy at the height is converted to kinetic energy.

Se usa una bombona de He para inflar globos, de volumen 15L con una presión de 200 atm. Si los globos tienen un volumen de 1.5L y presión de 770mmHg. ¿Cuántos globos se pueden llenar?
Answer:
La cantidad de globos llenos es de aproximadamente 1.974 globos
Explanation:
Los parámetros dados son;
El gas utilizado para inflar el globo = Él
El volumen del gas He, V₁ = 15 L
La presión del gas He, P₁ = 200 atm = 20,265,000 Pa
El volumen de cada globo = 1,5 L
La presión del He dentro del globo, P₂ = 770 mmHg = 102,641 Pa
Sea 'V₂', que represente el volumen total que el gas ocupa en todos los globos, y 'x', que represente el número de globos;
Por lo tanto, tenemos;
1,5 · x = V₂
Según la ley de Boyle, tenemos;
P₁ · V₁ = P₂ · V₂
∴ V₂ = P₁ · V₁ / (P₂)
Al introducir los valores conocidos, obtenemos;
V₂ = 20,265,000 Pa × 15 L / (102,641 Pa) = 2,961.53548 L
1,5 L × x = V₂
∴ 1,5 L × x = 2,961,53548 L
x = 2,961.53548 L / (1.5 L) = 1,974.35699 redondeamos hacia abajo para obtener un número entero de globos de la siguiente manera;
El número de globos, x ≈ 1,974 globos.

Answer:
Grades ... gravity affects them and the potential energy is converted into kinetic energy. Watching a Slinky move down the stairs or vibrating while ... and kinetic energy, and finally into sound waves.
Explanation:
Answer:
A wave as seen above will start losing energy by transferring it to kinetic and rotational energy at the shallow bottom including sand transfers, which finally will become heat (extra kinetic energy). ... In the end all energy will end up as a higher temperature in the region and ground than if the ocean were calm.
