The auxiliary equation is given by d^2x/dt^2 + (c/m) dx/dt + (k/m) x = 0. This can be found by force substituting m = 1kg, c = 6 kg s−1 and k = 9 kg s−2 into the given differential equation.

The general solution for equation (2.1) is given by:$$x(t) = c_1 e^{r_1 t} + c_2 e^{r_2 t}$$where r1 and r2 are the roots of the auxiliary equation and c1 and c2 are arbitrary constants. We can find the roots of the auxiliary equation by solving the characteristic equation:$$r^2 + (c/m)r + (k/m) = 0$$Using the quadratic formula, we get:$$r_{1,2} = \frac{-p \pm \sqrt{p^2 - 4q}}{2}$$where p = c/m and q = k/m. Depending on the values of p and q, there are three cases for the roots:r1 and r2 are real and distinct;r1 and r2 are complex conjugates;r1 and r2 are equal and real.

The system described by equation (2.1) exhibits overdamping, as the damping constant c is greater than the critical damping constant, given by 2√km, where k is the spring constant and m is the mass. Overdamping occurs when the damping force is strong enough to prevent the mass from oscillating.(d) ExplanationOnce the force sint is applied, the non-homogeneous second order differential equation that describes the mass spring damper system is:d^2x/dt^2 + (c/m) dx/dt + (k/m) x = sint.(e).

The electrical resistance of the 100-watt lamp cannot be determined based solely on the information provided.

The brightness of a lamp is primarily determined by its power consumption (wattage) and the efficiency of converting electrical energy into light. While a 100-watt lamp generally produces more light output than a 25-watt lamp, the resistance of the lamp depends on various factors, including its design, filament material, and operating conditions.

Resistance (measured in ohms) is related to the physical and electrical properties of the lamp's filament, such as its length, cross-sectional area, and resistivity. These factors, along with the applied voltage, determine the resistance of the lamp. Therefore, without additional information about the specific characteristics of the 100-watt lamp, it is not possible to determine its electrical resistance based solely on its wattage or brightness compared to a 25-watt lamp.

When direct current flows through an electrical coil, it generates a magnetic field.

If the direct current flowing through the coil is increasing, the magnetic field strength will also increase.

This, in turn, will cause the coil to generate a stronger electromagnetic force, which can be used for various purposes such as powering motors, generating electricity, and more.

However, if the current flow becomes too strong, it can cause the coil to overheat and potentially damage it.

Therefore, it's important to ensure that the coil is designed to handle the amount of current flowing through it to prevent any potential damage.

Electrons absorb energy from the flame and become excited Electrons absorb energy from the flame and become excited, which causes them to emit light.

Electrons absorb energy when they are excited from their ground state. This phenomenon is commonly observed in the study of atomic and molecular spectroscopy. When energy is absorbed by an atom or molecule, the electrons are pushed into an excited state with higher energy levels.

The amount of energy absorbed corresponds to the difference between the ground state and the excited state of the electrons. This absorbed energy can come in various forms, such as electromagnetic radiation or collisions with other particles. Once the electron is in an excited state, it can release the absorbed energy as light or heat, or it can be involved in chemical processes like bonding or reaction. The ability of electrons to absorb energy is essential for many processes in nature such as photosynthesis, vision, and energy transfer in electronic devices.

Answer: \(0.708\ mA\)

Explanation:

Given

\(E_o=20\ V/m\)

\(\omega =10^7\ s^{-1}\)

Cross-sectional area \(A=0.40\ m^2\)

Current density is given by

\(J=\epsilon_o \dfrac{dE}{dt}\)

Displacement current

\(\Rightarrow I=JA\\\Rightarrow I=8.854\times 10^{-12}\times 20\times 10^7\times 0.4\\\Rightarrow I=0.708\times 10^{-3}\ A\)

The required value of the maximum displacement current of the given space is  \(7.08 \times 10^{-4} \;\rm A\).

Given data:

The intensity of electric field is, \(E_{0}=20 \;\rm V/m\).

The angular frequency of electric field is, \(\omega=1.0 \times 10^{7} \;\rm s^{-1}\).

The cross-sectional area of space is, \(A =0.40 \;\rm m^{2}\).

In the given problem, the instantaneous electric field is given by \(E = E_{0} \times cos(\omega t)\)

So, the expression for the current density is,

\(J= \epsilon_{0} \times \dfrac{dE}{dt}\)

Here, \(\epsilon_{0}\)  is the permittivity of free space. Solving as,

\(J= \epsilon_{0} \times \dfrac{d(E_{0} \times cos(\omega t))}{dt}\\\\J= -\epsilon_{0} \times E_{0} \times \omega \times sin(\omega t)\)

And the expression for the maximum displacement current is,

\(I = J \times A\)

And the maximum displacement current is possible only when, J is positive and J will be positive for  \(sin(\omega t)=-1\).

Then solving as,

\(I = (-\epsilon_{0} \times E_{0} \times \omega \times sin(\omega t)) \times A\\\\I = (-8.85 \times 10^{-12} \times 20 \times (1.0 \times 10^{7}) \times (-1)) \times 0.40\\\\I = 7.08 \times 10^{-4} \;\rm A\)

Thus, we can conclude that the required value of the maximum displacement current of the given space is  \(7.08 \times 10^{-4} \;\rm A\).

When a blank was in the light path, a photometer with a linear response to radiation read 678.1 mV and 160.3 mV, respectively, when the blank was replaced with an absorbing solution, or 23.64%.

Using the given data, we can use the following formula to get the percentage of transmitted radiation: % Transmittance = (I / I₀) × 100

When ligand-gated channels open, the membrane potential of a neuron can swiftly change. There are two alternative modifications that might take place: depolarization, which is a movement towards a more positive potential, or hyperpolarization, which is a shift towards a more negative potential. The direction of the change depends on the ion that the channel allows to pass through.
where I0 denotes the radiation's starting intensity (when the blank is used), and I denotes the radiation's intensity after passing through the absorbing solution.

Given the information:

I = 160.3 mV (with the absorbing solution) and I₀  = 678.1 mV (with the blank).

Now, we can determine the transmittance percentage:

(160.3 mV/678.1 mV) / 100 x 23.64% = % Transmittance

The Hawthorne effect refers to the phenomenon where individuals change their behavior as a result of being observed or studied.  One example of how the Hawthorne effect can be applied in a workplace setting is through the use of employee engagement surveys. If a company conducts a survey to gather feedback on job satisfaction and engagement, employees may become more motivated and engaged as a result of feeling heard and valued. This can lead to improved productivity and job performance.

Benefits of this workplace design can be that it can increase worker productivity, job satisfaction, and reduce turnover rates. However, one disadvantage of this design that could occur from employees being observed is that it could lead to a lack of privacy and create a feeling of being constantly watched. This can lead to discomfort and mistrust among employees, which can ultimately reduce morale and productivity.

Additionally, the observed employees may become nervous and anxious while being observed, leading to false data. As a result, the Hawthorne effect must be considered and controlled for in any study that aims to measure the impact of changes in the workplace on employee behavior.

11.The time at 75° East longitude would be 1 hour and 20 minutes behind. 12.The time at 135° degrees East longitude would be 4 hours ahead. and 13. the time in Lima, Peru (15° South latitude, 75° West longitude) would also be 9:30 AM.

At 2:00 AM at 90° East longitude, the time at 75° East longitude would be 1 hour and 20 minutes behind. This is because for every 15 degrees of longitude, there is a time difference of approximately 1 hour. Since the two longitudes in question have a difference of 15 degrees, we can divide this by 15 to calculate the time difference.

If it is 8:00 PM at 15° East longitude, the time at 135° East longitude would be 4 hours ahead. Similarly, for every 15 degrees of longitude, there is an approximate time difference of 1 hour. Since the two longitudes in question have a difference of 120 degrees, we can divide this by 15 to calculate the time difference.

There is a 7-hour difference** between 105° West longitude and the Prime Meridian (0° longitude). The Prime Meridian, passing through Greenwich, England, serves as the reference point for determining time zones. As one moves westward from the Prime Meridian, each 15 degrees of longitude corresponds to a time difference of approximately 1 hour. Therefore, the time at 105° West longitude would be 7 hours behind the time at the Prime Meridian.

If it is 9:30 AM in New York (41° North latitude, 75° West longitude), the time in Lima, Peru (15° South latitude, 75° West longitude) would also be 9:30 AM. The latitude does not affect the time difference between the two locations. However, since both locations have the same longitude (75° West), they would experience the same local time. The time difference between different latitudes is primarily significant for determining time zones rather than the actual time within a specific time zone.

It has been determined that the 31.8 kg mass experiences a net gravitational force of 1.129105 N from the two larger masses.

The absolute or relative direction or size of an object's motion in the sense of motion can be used to define magnitude. It is extensively utilized to convey something's size or scope. In physics, the term "magnitude" typically means "distance" or "quantity."

Take the right to be positive.  Sum of forces on the 31.8 kg mass:

∑F = GM₁m / r₁² − GM₂m / r₂²

∑F = G (M₁ − M₂) m / r²

∑F = (6.672×10⁻¹¹ N kg²/m²) (516 kg − 207 kg) (31.8 kg) / (0.482 m / 2)²

∑F = 1.129×10⁻⁵ N.

Repeating the same steps, the second part this time ∑F = 0 and we're solving for r.

∑F = GM₁m / r₁² − GM₂m / r₂²

0 = GM₁m / r₁² − GM₂m / r₂²

GM₁m / r₁² = GM₂m / r₂²

M₁ / r₁² = M₂ / r₂²

516 / r² = 207 / (0.482 − r)²

516 (0.482 − r)² = 207 r²

516 (0.232 − 0.964 r + r²) = 207 r²

119.9 − 497.4 r + 516 r² = 207 r²

119.9 − 497.4 r + 309 r² = 0

r = 0.295 or 1.315.
