Answer:

Se obtienen 2,27 gramos de metanol.

Explanation:

La reacción entre monóxido de carbono e hidrógeno para producir metanol es la siguiente:

CO + 2H₂ → CH₃OH  

Para encontrar el reactivo limitante y el reactivo en exceso, debemos calcular el número de moles de CO y H₂:

\(\eta_{CO} = \frac{m}{M} \)              

En donde:    

m: es la masa

M: es el peso molecular  

\(\eta_{CO} = \frac{m}{M_{CO}} = \frac{2,0 g}{28,01 g/mol} = 0,071 moles \)

\(\eta_{H_{2}} = \frac{2,0 g}{2,02 g/mol} = 0,99 moles \)

Dado que la relación estequiométrica entre CO y H₂ es 1:2, el número de moles de hidrógeno gaseoso que reaccionan con el monóxido de carbono es:

\( \eta_{H_{2}} = \frac{2}{1}*0,071 = 0,142 moles \)      

Entonces, se necesitan 0,142 moles de H₂ para reaccionar con 0,071 moles de CO y debido a que se tienen más moles de H₂ (0,99 moles) entonces el reactivo limitante es CO y el reactivo en exceso es H₂.

Ahora podemos encontar la masa de metanol obtenida usando el reactivo limitante (CO) y sabiendo que la realcion estequiométrica entre CO y CH₃OH es 1:1.    

\( \eta_{CH_{3}OH} = \eta_{CO} = 0,071 moles \)

\( m = 0,071 moles*32,04 g/mol = 2,27 g \)

Por lo tanto, se obtienen 2,27 gramos de metanol.

Answer:

The force of gravitational attraction between the satellite and Earth is \(2.587\times 10^{10}\) newtons.

Explanation:

Statement is incorrect. Correct statement is:

A satellite (\(m = 4.44\times 10^{9}\,kg\)) travels in orbit around the Earth at a distance of \(1.9\times 10^{6}\,m\) above Earth's surface. What is the force of gravitational attraction between the satellite and Earth?

The gravitational force experimented by the satellite (\(F\)), in newtons, is calculated by Newton's Law of Gravitation, whose equation is defined by following formula:

\(F = \frac{G\cdot m \cdot M}{R^{2}}\) (1)

Where:

\(G\) - Gravitational constant, in cubic meters per kilogram-square second.

\(m\) - Mass of the satellite, in kilograms.

\(M\) - Mass of the Earth, in kilograms.

\(R\) - Distance of the satellite with respect to the center of the Earth, measured in meters.

If we know that \(G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}\), \(m = 4.44\times 10^{9}\,kg\), \(M = 5.972\times 10^{24}\,kg\) and \(R = 8.271\times 10^{6}\,m\), then the force of gravitational attraction between the satellite and Earth is:

\(F = 2.587\times 10^{10}\,N\)

The force of gravitational attraction between the satellite and Earth is \(2.587\times 10^{10}\) newtons.

Answer:

Distance the boat would travel going upstream = 160 km

Explanation:

First, the time of travel of the boat downstream is calculated.

Time of travel = distance/speed

distance = 240 km;

speed of travel = 40 + 8 = 48 km/h ( since the boat is going downstream)

Time = 240/48 = 5 hours

Therefore, the boat travels for 5 hours.

The distance the boat will travel in 5 hours going upstream is then calculated

distance = speed * time

speed of boat  going upstream = 40 - 8 = 32 km/h

Distance = 32 km/h * 5 hours = 160 km

To derive the algebraic equation for the vertical force, we must consider the forces acting in the vertical direction and apply Newton's second law of motion.

Newton's second law states that the net force acting on an object is equal to the product of its mass (m) and its acceleration (a). In the vertical direction, the forces that typically act on an object are gravity and any other forces such as the normal force or applied forces.

Assume that the vertical force is denoted as Fv. Forces acting in the vertical direction are typically mass (mg) and the normal force (N) exerted by the surface, if present. Therefore, the equation for the vertical force can be expressed as:

Fv = N - mg,

where:

Fv is the vertical force,

N is the normal force,

m is the mass of the object,

g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).

The normal force N is equal to the weight of the object if the object is at rest on a horizontal surface. In this case, N = mg. However, if the object is on an inclined plane or is subject to other forces, the normal force may differ from the weight.

By substituting the appropriate values ​​for the normal force and mass (mg), you can derive an algebraic equation for the vertical force based on the specific scenario you are considering.

Answer:

10s to reverse velocity in opposite direction

Explanation:

Momentum = mass * velocity

The objects initial momentum therefore is 0.4*30=12Ns

Time = momentum / force

In order to stop the object's momentum, a force of 2N would thereforehave to be applied for 12/2=5s

In order to reverse the velocity of the object in the opposite direction, it would take twice this: 10s

The cue ball's final velocity is 0.453 m/s, or 0.90 m/s.

The pace at which an item goes in one direction is known as its velocity. As the velocity of a car driving northward on a highway or the pace at which a rocket takes off. The vector quantity velocity (v), denoted by the formula v = s/t, quantifies deformation (or shift in position, s), over change in time (t).

The displacement that such an object or particles experiences with regards to time is expressed vectorially as velocity. The meters per second (m/s) is the accepted unit of velocity profile (sometimes known as speed).

Let "v" represent the ball's ultimate speed.

Apply the law of linear momentum conservation.

Total initial momentum is = Total final momentum

=(0.17 x 1.3) + (0.16 x 0) = (0.17 x v) + (0.16 x 0.90)

0.221 = 0.17v + 0.144

The  speed when it hits the ground is option (B) 15.5 m/s.

To determine the speed of the object when it hits the ground, we can use the principle of conservation of energy. The initial potential energy of the object is converted into kinetic energy as it falls.

The change in gravitational potential energy is given as ΔPE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height.

We know that ΔPE = 565 J, and the height h = 12.0 m.

Since the object is initially at rest, its initial kinetic energy is zero.

The total mechanical energy (sum of potential and kinetic energy) is conserved, so:

ΔPE = ΔKE

mgh = (1/2)mv^2

Here, m cancels out, giving:

gh = (1/2)v^2

Substituting the known values:

(9.8 m/s^2)(12.0 m) = (1/2)v^2

117.6 = (1/2)v^2

Dividing both sides by (1/2):

235.2 = v^2

Taking the square root of both sides:

v ≈ 15.33 m/s

Therefore, the speed of the object when it hits the ground is approximately 15.33 m/s.

A vibrating stretched string has length 104 cm, mass 26.3 grams and is under a tension of 71.9 Newton. The frequency of the 10th harmonic is 286.9 Hz.

Let's begin the solution to this problem:

The speed of the wave on the string is given by:v = √(T/μ)

Here, T is the tension in the string and μ is its linear density (mass per unit length).μ = m/l

where m is the mass of the string and l is its length.

Using these values in the equation for v, we get:

v = √(T/μ) = √(Tl/m)

Next, we can find the frequency of the nth harmonic using the formula:f_n = n(v/2l)

Where n is the harmonic number, v is the speed of the wave on the string, and l is the length of the string.

Given data:

length l = 104 cm = 1.04 m

mass m = 26.3 gm = 0.0263 kg

Tension T = 71.9 N

For the given string:

f_10 = 10(v/2l)

The speed of wave on string:

v = √(Tl/m) = √[(71.9 N)(1.04 m)] / 0.0263 kgv = 59.6 m/s

Substitute the value of v in the equation for frequency:

f_10 = 10(59.6 m/s) / [2(1.04 m)]

f_10 = 286.9 Hz

When moving through an EMF device that is connected to a resistor, the potential will decrease. Therefore, option a is the correct answer.

When a conductor is moved through an EMF device that is connected to a resistor, the potential difference between the two ends of the resistor is given by Ohm's law, which states that V = IR, where V is the potential difference, I is the current flowing through the resistor, and R is the resistance of the resistor.

Therefore, the potential difference across the resistor depends on the direction of the current flow through the resistor, which in turn depends on the direction of the EMF and the direction of the motion of the conductor.

If the conductor is moved in the direction of the EMF arrow, the current flows in the opposite direction, from the negative terminal of the EMF device through the conductor and into the positive terminal. In this case, the potential difference across the resistor is given by V = -IR, which means that the potential decreases as the conductor moves through the EMF device.

Therefore, option (a) is correct: If you move in the direction of the EMF arrow, the potential decreases.

Answer:

The data that we have is:

Initial height = 2m

Initial vertical speed: As the sister is only pushed, we can assume that we do not have initial speed in the vertical axis.

Then at the beginning, we only have potential energy, that (using the water as the zero in our axis) can be written as:

U = m*g*h

where m is the mass of your sister, g is the gravitational acceleration, and h is the initial height:

h = 2m

g = 9.8m/s^2

Now, when your sister is about to touch the water, all the potential energy has be transformed into kinetic energy:

K = (m/2)*v^2

Then we have, at that moment:

K = U

(m/2)*v^2 = m*g*h

We want to solve this for v, that is the velocity.

v = √(2*g*h) = √(2*9.8m/s^2*2m) = 6.26 m/s

So the speed at which your sister hits the water is 6.26 m/s

The speed at which the motor will run on no-load can be determined by using the concept of the motor's input and output power.
Given:
Full-load power (output power) = 7.5 kW
Full-load efficiency = 86% = 0.86
Total no-load input power = 600 W
First, we can calculate the full-load input power using the efficiency formula:
Full-load input power = Full-load power / Full-load efficiency
Full-load input power = 7.5 kW / 0.86 = 8.72 kW
Now, we can determine the ratio of the no-load input power to the full-load input power:
Power ratio = Total no-load input power / Full-load input power
Power ratio = 600 W / 8.72 kW = 0.0688
Since power is directly proportional to the speed of the motor, we ca
calculate the speed on no-load using the power ratio
No-load speed = Full-load speed * √(Power ratio)
No-load speed = 1,200 r/min * √(0.0688) ≈ 292.78 r/min
Therefore, the motor will run at approximately 292.78 r/min on no-load.
1.2.2 To reduce the speed to 1,000 r/min when giving full-load torque, we need to add a resistance in the armature circuit. The speed of the motor is inversely proportional to the armature circuit resistance.
Given:
Full-load speed = 1,200 r/min
Target speed = 1,000 r/min
Using the speed ratio formula:
Speed ratio = Full-load speed / Target speed
Speed ratio = 1,200 r/min / 1,000 r/min = 1.2
Since the speed is inversely proportional to the resistance, we can calculate the resistance ratio:
Resistance ratio = 1 / Speed ratio
Resistance ratio = 1 / 1.2 ≈ 0.833
Now, we can calculate the required resistance to be added in the armature circuit:
Required resistance = Armature circuit resistance * Resistance ratio
Required resistance = 0.3 ohm * 0.833 ≈ 0.25 ohm
Therefore, a resistance of approximately 0.25 ohm needs to be added in the armature circuit to reduce the speed to 1,000 r/min when giving full-load torque, assuming the flux is proportional to the field current.
