Assume a firm closes down in the short run and produces no output. Under these conditions:A. TVC is positive, but TFC and TC are zero.B. TFC is positive, but TVC and TC are zero.C. TFC and TC are positive, but TVC is zero.D. TFC, TVC, and TC will all be positive.
Answers
The correct answer is C.
In this case, Total Fixed Costs (TFC) remain positive as they are the expenses that do not change with the level of output, such as rent, salaries, and depreciation. Total Variable Costs (TVC) are zero since there is no production, and variable costs depend on the level of output. Total Costs (TC) remain positive as they are the sum of TFC and TVC, and since TFC is positive, TC will also be positive.

Answers
The speed of the stopper is 4.95 m/s, while the centripetal force on the stopper and the tension in the string is 3.42N each.
The mass of the stopper is 0.13 Kg, the length of the string to which it is attached is 0.93 m. The stopper swung and made one revolution in 1.18 seconds, so the time period of revolution of the stopper is 1.18 seconds.
The relation between the time period and the angular speed is,
T = 2π/W
W is angular speed and T is the time period of revolution.
Putting values,
1.18 = 2π/W
W = 5.32 rad/s.
The speed of the stopper can be found as,
v = rW
r is the length of the string,
V = 4.95 m/s.
The centripetal force on the stopper is given by,
F = MV²/r
Putting values,
F = 0.13 x 4.95 x 4.95/0.93
F = 3.42 N.
The tension in the string will be equal to the centripetal force on the stopper, so, the tension is 3.

Consider a father pushing a child on a playground merry-go-round. The system has a moment of inertia of 84.4 kg • m2. The father exerts a force on themerry-go-round perpendicular to its radius to achieve an angular acceleration of 4.44 rad/s2.(a) How long (in s) does it take the father to give the merry-go-round an angular velocity of 2.29 rad/s? (Assume the merry-go-round is initially atrest.)S(b) How many revolutions must he go through to generate this velocity?revolutions(C) If he exerts a slowing force of 270 N at a radius of 1.25 m, how long (in s) would it take him to stop them?s
Answers
a)
Since we have a constant angular acceleration we have that:
\(\alpha=\frac{\omega-\omega_0}{t}\)Plugging the values we know we have that:
\(\begin{gathered} 4.44=\frac{2.29-0}{t} \\ t=\frac{2.29}{4.44} \\ t=0.516 \end{gathered}\)Therefore it will take 0.516 (rounded to three decimals) seconds to achive this angular velocity.
b)
To find how many revolutions he needs we first calculate the change in angular position using the formula:
\(\begin{gathered} \omega^2-\omega^2_0=2\alpha(\theta-\theta_0) \\ (\theta-\theta_0)=\frac{\omega^2-\omega^2_0}{2\alpha} \\ (\theta-\theta_0)=\frac{2.29^2-0^2}{2(4.44)} \\ (\theta-\theta_0)=0.590551801 \end{gathered}\)Now we divide this change in angular position by 2pi (the angle equivalent to a revolution) to get the revolutions:
\(\frac{0.590551801}{2\pi}=0.094\)Therefore it takes 0.094 (round to three decimals) revolutions to get to this angular velocity.
c)
The torque is the force by the radius, then we have:
\(\tau=(270)(1.25)=337.5\)But the torque is also equal to the moment of inertia multiplied by the angular acceleration:
\(\tau=I\alpha\)Then we have:
\(\begin{gathered} 337.5=84.4\alpha \\ \alpha=\frac{337.5}{84.4} \\ \alpha=3.998815166 \end{gathered}\)Now we use the formula for angular acceleration to get the time:
\(\begin{gathered} -3.998815166=\frac{0-2.29}{t} \\ t=\frac{-2.29}{-3.998815166} \\ t=0.573 \end{gathered}\)Therefore it takes 0.573 seconds to stop the merry go round.

Two horizontal wires with identical in magnitude currents carry currents: left wire directly towards you, right wire away from you. As viewed from your position, magnetic field exactly midway between wires is: _______
Answers
The magnetic field exactly midway between the two wires, as viewed from your position, will be zero.
The magnetic field produced by a straight current-carrying wire is given by Ampere's law, where r is the distance from the wire, I is the current, 0 is the permeability of space (constant), and B is the magnetic field.
For the left wire, the magnetic field points towards you, while for the right wire, it points away from you. Since the wires are identical in magnitude of current and are placed symmetrically, the magnetic fields they produce at the midpoint will have the same magnitude but opposite directions.
At the midpoint, the magnetic fields of the two wires cancel each other out due to their equal magnitude but opposite directions. Hence, the net magnetic field at the midpoint is zero.
The magnetic field exactly midway between the two wires, as viewed from your position, is zero.

Answers
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.

(b) What is the probability that the electron can be detected in the middle one third of well, region (b)
Answers
In order to determine the probability that an electron can be detected in the middle one-third of a well region, we need to take into account the wave function and the boundary conditions.The wave function represents the probability density of finding the electron in a particular location within the well. The boundary conditions are determined by the geometry of the well, which can be rectangular, triangular, or other shapes.
The Schrodinger equation is used to calculate the wave function and determine the probability density of finding the electron in a particular location. The wave function is a complex function that describes the position and momentum of the electron. It is also used to calculate the energy of the electron in the well.The probability of finding the electron in the middle one-third of the well can be determined by integrating the probability density over the middle one-third of the well region. This will give us the probability of finding the electron in that region. The integral can be evaluated using numerical methods or analytical methods, depending on the complexity of the wave function and the boundary conditions.In general, the probability of finding the electron in the middle one-third of the well will depend on the shape of the well, the energy of the electron, and the boundary conditions. For example, if the well is rectangular and the electron is in the ground state, then the probability of finding the electron in the middle one-third of the well will be high. However, if the well is triangular and the electron is in an excited state, then the probability of finding the electron in the middle one-third of the well will be lower.For such more question on probability

if there are two waves A and B with their amplituds 3 cm and 4 cm respectively compared it's loudness and tell which one is more louder
Answers
Wave B will be louder than wave A.
Let the amplitude of wave A be a1 and the amplitude of wave B be a2.
Similarly, let the loudness of wave A be L1 and the loudness of wave B be L2.
We know,
\(\frac{L1}{L2}\) = \(\frac{a1^{2} }{a2^{2} }\)
By substitution we see:
\(\frac{L1}{L2}\) = \(\frac{3^{2} }{4^{2} }\)
We get:
\(\frac{L1}{L2}\) = \(\frac{9}{16}\) .
Thus we see that the loudness of wave A is 9Hz while that of wave B is 16Hz. So we conclude that wave B is louder than wave A.

Resistance in metals increases with increasing temperature according to the equation, rho (T) rhoₒ(1 + α (T-Tₒ)) where α is the temperature coefficient of resistivity and rhoₒ is the resistivity at temperature Tₒ For a particular wire α = 5.5 x 10⁻³ 1/°C and the resistivity and is rhoₒ = 4.5x 10.7 Ω·m at Tₒ = 229 °C
Part (a) Input an expression for the temperature T₂ at which the resistance of a wire will be twice as high as as at Tₒ.
T₂ = _________
Part (b) What is this temperature, in degrees Celcius?
Part (c) If the wire is L = 1 m long with a radius of r = 1 cm, what is its resistance R, in Ω, at 2 Tₒ?
Answers
(a) T₂ = Tₒ + (2ρₒ - ρₒ) / (αρₒ), (b) Substitute values to find T₂ in °C, (c) Use R = ρ(T) * (L / A) to find resistance R at 2Tₒ.
Part (a) To find the temperature T₂ at which the resistance of the wire will be twice as high as at Tₒ, we can set up the equation:
2ρₒ(1 + α(T₂ - Tₒ)) = ρₒ(1 + α(T - Tₒ))
By simplifying and cancelling ρₒ on both sides, we get:
2(1 + α(T₂ - Tₒ)) = 1 + α(T - Tₒ)
Expanding and rearranging the equation, we have:
2αT₂ - 2αTₒ + 2 = αT - αTₒ
2αT₂ = αT + (2αTₒ - αTₒ - 2)
2αT₂ = αT + αTₒ - 2αTₒ + αTₒ - 2
2αT₂ = αT - αTₒ - 2
Dividing both sides by 2α, we obtain:
T₂ = (αT - αTₒ - 2) / (2α)
Part (b) To find the temperature T₂ in degrees Celsius, we substitute the given values:
T₂ = (5.5x10⁻³T - 5.5x10⁻³(229) - 2) / (2x5.5x10⁻³)
T₂ = (5.5x10⁻³T - 1.2595 - 2) / (11x10⁻³)
T₂ = (5.5x10⁻³T - 3.2595) / (11x10⁻³)
Part (c) To find the resistance R at 2Tₒ, we use the formula for resistance:
R = (ρL) / A
where ρ is the resistivity, L is the length, and A is the cross-sectional area. Given the wire length L = 1 m and the radius r = 1 cm (which is equal to 0.01 m), we can calculate the cross-sectional area A:
A = πr² = π(0.01)² = 0.0001π m²
Substituting the given resistivity ρₒ = 4.5x10⁻⁷ Ω·m at Tₒ = 229 °C, we can calculate the resistance R at 2Tₒ:
R = (ρL) / A = (4.5x10⁻⁷)(1) / (0.0001π) = 0.045 / π Ω
Therefore, the resistance R at 2Tₒ is approximately 0.045 / π Ω.
