A refrigerator should remove 400kJ from some food. Assume the refrigerator works in a Carnot cycle between -15°C and 45°C with a motor-compressor of 400W. How much time does it take if this is the only cooling load?

Answers

Answer 1

It takes 5,302.4 seconds (or about 1 hour and 28 minutes) for the refrigerator to remove 400 kJ of energy if this is the only cooling load.

To determine the time required for the refrigerator to remove 400 kJ of energy, we need to calculate the efficiency of the Carnot cycle and then use it to determine the total energy supplied by the motor-compressor over that time period.

The efficiency (η) of a Carnot cycle is given by the formula:

η = 1 - (Tc/Th)

where Tc is the absolute temperature of the cold reservoir and Th is the absolute temperature of the hot reservoir.

Given that the temperature range of the Carnot cycle is from -15°C to 45°C, we need to convert these temperatures to Kelvin:

Tc = 273 + (-15) = 258 K

Th = 273 + 45 = 318 K

Now we can calculate the efficiency:

η = 1 - (258/318) = 0.1887

The efficiency represents the fraction of energy that is effectively used by the refrigerator. So, the total energy supplied by the motor-compressor (W) can be calculated by dividing the energy required to remove (Q) by the efficiency:

Q = 400 kJ = 400,000 J

W = Q / η = 400,000 J / 0.1887 = 2,120,953 J

Since power (P) is defined as energy (W) divided by time (t), we can rearrange the equation to solve for time:

t = W / P = 2,120,953 J / 400 W = 5,302.3825 seconds

Therefore, it would take approximately 5,302.4 seconds (or about 1 hour and 28 minutes) for the refrigerator to remove 400 kJ of energy if this is the only cooling load.

Answers

Cyclotron to make 1 milligram of the isotope fluorine-18 for use a a diagnostic tool with it PET scanner. It seems that the hospital should plan to make more F-18 the next morning, as the amount remaining at midnight is very small.

The half-life of F-18 is 1.8 hours, so after 1.8 hours, half of the original amount of F-18 will remain. After 3.6 hours, a quarter of the original amount will remain, and so on.

At 3:00 PM (9 hours after the F-18 was made), the hospital will have

= 1/2^(9/1.8)

= 1/2^5

= 1/32

= approximately 0.03125 milligrams of F-18 remaining.

At midnight (18 hours after the F-18 was made), the hospital will have

= 1/2^(18/1.8)

= 1/2^10

= 1/1024

= approximately 0.0009765625 milligrams of F-18 remaining.

While using cyclotron, based on these calculations, it seems that the hospital should plan to make more F-18 the next morning, as the amount remaining at midnight is very small.

what happens to the current in a circuit if a 1.5 volt battery is removed and is placed by a 9 volt battery?

Answers

Answer:

The current would increase.

Explanation:

The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the less the current and the greater the current the less the resistance is.

if a 1.5-volt battery is removed and placed by a 9-volt battery in a circuit, From Ohm's law we can say that the current flow inside the circuit will increase because the voltage increases (resistance remains constant).

What is Ohm's law?

Ohm's Law is a fundamental law of physics that describes the relationship between the three basic electrical quantities: voltage, current, and resistance in a circuit.

It states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, Ohm's Law is expressed as:

V = I x R

Where:

V = the voltage or potential difference between two points in the circuit,       measured in volts (V).

I = the current flowing through the circuit, measured in amperes (A).

R = the resistance of the conductor, measured in ohms (Ω).

In other words, the voltage (V) across a circuit component is equal to the product of the current (I) flowing through the component and its resistance (R). This law is applicable to both DC (direct current) and AC (alternating current) circuits, as long as the resistance is constant.

Ohm's Law can be used to calculate any one of the three variables if the other two are known. For example, if the voltage and resistance in a circuit are known, the current flowing through the circuit can be calculated using the formula:

I = V / R

Here in the question,

The current in a circuit is determined by the resistance of the circuit and the voltage applied to it, according to Ohm's Law. If a 9-volt battery replaces a 1.5-volt battery, the voltage applied to the circuit will increase, which may cause an increase in the current flowing through the circuit if the resistance remains the same.

However, the increase in voltage may also cause an increase in the heat generated by the circuit, which could potentially damage the components or cause a safety hazard. Therefore, it is important to ensure that the components in the circuit can handle the higher voltage before replacing the battery.

It's also important to note that the current may also depend on the internal resistance of the batteries. A 9-volt battery typically has a lower internal resistance than a 1.5-volt battery, which means it can supply more current to the circuit. So, even if the resistance of the circuit remains the same, the current may still increase due to the higher voltage and lower internal resistance of the 9-volt battery.

Hence, The current flowing through the circuit increased when we removed a 1.5-volt battery and replaced it with a 9-volt battery.

When you create a best fit line what is the expected value of the slope?

Answers

When you create a best-fit line, the expected value of the slope represents the average rate of change in the dependent variable (y) for every unit increase in the independent variable (x). The slope helps you make predictions and understand the relationship between the two variables in your dataset.

When you create a best-fit line, the expected value of the slope is the coefficient that represents the rate of change between the two variables being analyzed. The slope is determined by finding the ratio of the change in the dependent variable to the change in the independent variable.

It is important to note that the slope of a best-fit line is not always a perfect representation of the true relationship between the variables, but rather an approximation based on the available data. Therefore, the expected value of the slope is subject to variation and uncertainty depending on the specific data set and methodology used to create the best-fit line.

Answers

The answer is False. A polarized material does not need to have a nonzero net electric charge. Polarization occurs when the positive and negative charges within a material are displaced relative to each other, creating an electric dipole moment.

This can happen in materials such as dielectrics or insulators, which do not conduct electricity. The net electric charge of a polarized material can still be zero, as the overall positive and negative charges remain balanced, but the charges are spatially separated. Polarization plays an important role in phenomena such as capacitance, dielectric constant, and polarization-induced electric fields.

Electrolytes are compounds that conduct electricity in aqueous solutions. For a compound to be considered an electrolyte, what must happen when it dissolves in water?

Answers

When a compound dissolves in water to become an electrolyte, it must dissociate or break apart into ions.

These ions are then able to carry an electrical charge and conduct electricity in the aqueous solution. The greater the degree of dissociation, the stronger the electrolyte will be.

For example, when sodium chloride (NaCl) dissolves in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-). These ions are then able to conduct electricity in the solution.

In contrast, a compound that does not dissociate into ions when dissolved in water is considered a nonelectrolyte and will not conduct electricity.

In summary, for a compound to be considered an electrolyte, it must dissociate into ions when dissolved in water, allowing it to conduct electricity in the aqueous solution.

Objects 1 and 2 attract each other with an electrostatic force of 8 units. If the charge of Object 1 is multiplied by 1 AND the charge of object 2 is multiplied by 3 AND the distance separating Objects 1 and 2 is divided by 4, then the new electrostatic force will be _____ units.

Answers

The new electrostatic force will be 384 units.  

The electrostatic force of attraction between two charges \(q_{1} \\\)(charge of object 1)  and \(q_{2}\)(charge of object 2) separated by a distance d is given by

\(F = \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

\(E_{0} = 8.854 * 10^{-12} C^{2} N^{-1} m^{-1}\) is the permittivity of free space.

Initially, we have,

\(\frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } =F_{1} = 8 units\)  

Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, \(q_{1} =q_{1}, q_{2} =3q_{2} , d=\frac{d}{4}\).

The new electrostatic force will be,

\(F_{2} = \frac{q_{1} 3q_{2}}{4\pi E_{0} (\frac{d}{4} )^{2} } \\\\\) units.

We have, \(F_{1} = 8 units= \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

Hence,

\(F_{2} =\frac{8*3}{(\frac{1}{4}) ^{2} } units= 384 units.\)

Hence, the new electrostatic force will be 384 units.

What is the velocity of the sled at the bottom of the hill (just before impact)?

Answers

The frictional force between the sled and block (stuck together) and the flat ground is 147 N.

The normal force is the force exerted on an object perpendicular to the surface it is in contact with, and it can be calculated by using the weight of the object (mg). In this case, the weight of the sled and block (stuck together) is 12 kg + 8 kg = 20 kg. So, the normal force is 20 kg * 9.8 m/s^2 = 196 N.

Using the coefficient of friction provided (µ = .75), we can calculate the frictional force as:

friction = .75 * 196 N = 147 N.

So, the frictional force between the sled and block (stuck together) and the flat ground is 147 N.

2.a transverse wave is traveling down a rope with mass, m = 10 kg, and length, l = 50 m. if the rope is under a tension force of 2000 n, what is the wave speed of the transverse wave?

Answers

The wave speed of a transverse wave traveling down a rope can be determined using the formula v = √(T/μ), where v represents the wave speed, T is the tension force, and μ is the linear mass density of the rope.

To find the linear mass density, we divide the mass of the rope (m) by its length (l): μ = m/l.

Given that the mass of the rope is 10 kg and the length is 50 m, the linear mass density is μ = 10 kg / 50 m = 0.2 kg/m.

Substituting the values of T = 2000 N and μ = 0.2 kg/m into the formula for wave speed, we have:

v = √(2000 N / 0.2 kg/m)

  = √(10000 m^2/s^2 / kg/m)

  = √(10000 m^2/s^2) (canceling out the units)

  = 100 m/s

Therefore, the wave speed of the transverse wave traveling down the rope is 100 m/s.

No, the object's displacement and distance traveled will be equal; however, because the object's initial position is unknown, the object's position may differ from its displacement and distance traveled.

Because the initial position is not provided, we cannot assert that the displacement or distance equals the position. We might have arrived at a different conclusion if the starting point had been zero, because the distance from zero equals the position.

What precisely do you mean by position, displacement, and distance?

The location of an object (whether a person, a ball, or a particle) at a given point in time is referred to as its position. The displacement of an object is the difference in its position from one time to the next. Distance is the total amount the object has traveled in a certain period of time.

The agency requires that all documents be sent there by post, and all documents are certified copies of the originals. The agency sends back its assessments to the university by post as well. Assuming the degree verification is successful, the results of the English language test are then checked online by an officer at the admissions office. If the validity of the English test results cannot be verified, the application is rejected (notification of such refusal is sent by email). Once all certain student documents have been validated, the admissions office forwards these documents by internal mail to the relevant academic committee which is responsible for deciding whether to offer admission or not. The committee makes decisions based on academic degrees and transcripts, CVs, and letters of reference. The Committee meets every three months to examine all applications that are ready for academic assessment at the time of the meeting.At the end of the committee meeting, the committee chairperson notifies the admissions office of the selection results. This notification includes a list of accepted and rejected candidates. A few days later, the admissions office notifies each candidate of the results via email. In addition, successful candidates are sent a confirmation letter by post.Related issues:Process owners are concerned about the costs of the process and the fact that good candidates lose out to competing universities during the admissions process. Concretely, the data states that 30% of students who received the offer rejected it, and of that number, 30% of them rejected the offer because they received an offer from a competing university. Interviews as well as data from applicant surveys reveal that one of the problems facing universities is that students have to wait too long to find out the results of their applications. It often happens that by the time a student is admitted, the student has decided to go to another university instead.Task:1.
