The final charge on the capacitor is 72 μC.

We can use the formula for the charge on a capacitor in an RC circuit:

Q = C * V * (1 - e^(-t/RC))

where

Q is the charge on the capacitor,

C is the capacitance,

V is the voltage of the battery,

t is the time,

R is the resistance, and

e is the mathematical constant approximately equal to 2.71828.

Given: V = 8.0 V, R = 1 Ω, C = 9 μF, and the capacitor is initially uncharged.

Since the capacitor is initially uncharged, we can assume that Q = 0 at t = 0.

Then, we can solve for Q at t → infinity:

Q = C * V * (1 - e^(-t/RC))

Q = 9 μF * 8.0 V * (1 - e^(-∞))

Q = 9 μF * 8.0 V * (1 - 0)

Q = 72 μC

Therefore, the final charge on the capacitor is 72 μC.

Answer:

La masa del objeto es 270.027 kilogramos.

Explanation:

Asumamos que el cuerpo decelera a tasa constante, entonces podemos calcularlo por medio de la siguiente ecuación cinemática:

\(a = \frac{v-v_{o}}{t}\) (1)

Donde:

\(v_{o}\) - Velocidad inicial, en metros por segundo.

\(v\) - Velocidad final, en metros por segundo.

\(t\) - Tiempo, en segundos.

\(a\) - Deceleración, en metros per segundo al cuadrado.

Si sabemos que \(v_{o} = 33.889\,\frac{m}{s}\), \(v = 13.889\,\frac{m}{s}\) y \(t = 4.5\,s\), entonces la deceleración experimentada por el cuerpo es:

\(a = \frac{v-v_{o}}{t}\)

\(a = -4.444\,\frac{m}{s^{2}}\)

Por las Leyes de Newton, tenemos que la masa del cuerpo se calcula a partir de la siguiente expresión:

\(m = \frac{F}{a}\) (2)

Donde:

\(m\) - Masa, en kilogramos.

\(F\) - Fuerza de frenado, en newtons.

Si sabemos que \(F = -1200\,N\) y \(a = -4.444\,\frac{m}{s^{2}}\), entonces la masa del cuerpo es:

\(m = \frac{F}{a}\)

\(m = 270.027\,kg\)

La masa del objeto es 270.027 kilogramos.

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

Seismic waves move at 8 to 10 km/s in the Earth's outer core and 11 to 12 km/s in the Earth's inner core. This means that the inner core is denser. The speed difference is caused by differences in the composition of the layers.

Seismic waves are sensitive to the density and elasticity of the material they travel through. Generally, the speed of seismic waves increases with the density and elasticity of the material. Therefore, since the speed of seismic waves is faster in Earth's inner core than in the outer core, the inner core is expected to be denser than the outer core.

This is consistent with the current understanding of the composition of the Earth's core. The outer core is primarily composed of liquid iron and nickel, with some lighter elements, while the inner core is believed to be composed mostly of solid iron with some heavier elements. The denser materials in the inner core would explain why seismic waves travel faster in that layer.

In summary, the difference in the speed of seismic waves between the outer and inner cores suggests that the inner core is denser than the outer core.

The wiped area on a steamy mirror will be approximately half the vertical dimension of your face. Assuming your face is roughly symmetrical, the vertical dimension of your face can be divided into two equal halves.

When you wipe away the steam on a mirror, the wiped area will be approximately half the vertical dimension of your face. This is because the steam condenses on the mirror and creates a thin layer of moisture. When you wipe away this moisture, you reveal the reflective surface of the mirror beneath.

Assuming your face is roughly symmetrical, the vertical dimension of your face can be divided into two equal halves. When you wipe away the steam on the mirror, you remove the moisture in the shape of your face, leaving behind a clean area that corresponds to half of the vertical dimension.

It is important to note that the actual height of the wiped area may vary slightly depending on factors such as the size and shape of your face, the pressure applied during wiping, and the efficiency of the wiping action.

A frictionless piston-cylinder device contains 7.5 liters of saturated liquid water at 275 kPa. An electric resistance is turned on until 3050 kJ of energy is transferred to the water.

i) The mass of water can be determined by using the specific volume of saturated liquid water at the given pressure and volume. By using the specific volume data from the steam tables, the mass of water is calculated to be 6.66 kg.

ii) To find the final enthalpy of water, we need to consider the energy added to the water. The change in enthalpy can be calculated using the energy equation Q = m(h2 - h1), where Q is the energy transferred, m is the mass of water, and h1 and h2 are the initial and final enthalpies, respectively. Rearranging the equation, we find that the final enthalpy of water is 454.55 kJ/kg.

iii) The final state and the quality (x) of water can be determined by using the final enthalpy value. The final enthalpy falls within the region of superheated vapor, indicating that the water has completely evaporated. Therefore, the final state is a superheated vapor and the quality is 1 (x = 1).

iv) The change in entropy of water can be obtained by using the entropy equation ΔS = m(s2 - s1), where ΔS is the change in entropy, m is the mass of water, and s1 and s2 are the initial and final entropies, respectively. The change in entropy is found to be 10.13 kJ/kg.

v) The process described is irreversible because the water started as a saturated liquid and ended up as a superheated vapor, indicating that irreversibilities such as heat transfer across a finite temperature difference and friction have occurred. Therefore, the process is irreversible.

On a P-v diagram, the process can be represented as a vertical line from the initial saturated liquid state to the final superheated vapor state, crossing the saturation lines.

Explanation:

Simply, the reason for this is because the density of the atmosphere decreases gradually as you increase in altitude closer to space.

The winds aloft chart for the Great Lakes (Michigan is fine) region displays the wind direction and speed at several altitudes. At 3000 feet, the wind speed is approximately 17 knots.

At 12,000 feet, the wind speed is about 44 knots. The wind speed at FL350 is approximately 67 knots.Surface friction has an effect on the winds close to the ground, slowing them down due to the frictional force exerted on the ground by air molecules. The winds shift direction with altitude, veering to the right of the direction of travel in the northern hemisphere. The approximate location of the Jetstream can be obtained by examining the wind/temperature plot chart. The fastest wind speed at FL360 appears to be approximately 145 knots, traveling towards the northeast. Flight to the east or southeast would benefit from this wind speed.Seasonally, winds aloft change depending on the position of the jet stream, which moves towards the poles during the summer months and towards the equator during the winter months.
