Explanation:

When light passes through a narrow slit, it diffracts and creates a pattern of bright and dark regions known as a diffraction pattern. The angular deflection of the first diffraction minimum, also called the first dark fringe, can be calculated using the following formula:

θ = λ / (2 * w)

where θ is the angular deflection, λ is the wavelength of light, and w is the width of the slit.

a) For a slit width of 0.020 mm and a wavelength of 630 nm (or 630 × 10^(-9) m), we can calculate the angular deflection as follows:

θ = (630 × 10^(-9) m) / (2 * 0.020 × 10^(-3) m) = 0.01575 radians

b) For a slit width of 0.20 mm, using the same wavelength, we have:

θ = (630 × 10^(-9) m) / (2 * 0.20 × 10^(-3) m) = 0.001575 radians

c) For a slit width of 2.0 mm:

θ = (630 × 10^(-9) m) / (2 * 2.0 × 10^(-3) m) = 0.0001575 radians

To convert the angular deflection to degrees, we can multiply the value by (180/π):

a) θ = 0.01575 * (180/π) ≈ 0.902 degrees

b) θ = 0.001575 * (180/π) ≈ 0.0902 degrees

c) θ = 0.0001575 * (180/π) ≈ 0.00902 degrees

Therefore, the angular deflection of the first diffraction minimum for the given slit widths is approximately 0.902 degrees, 0.0902 degrees, and 0.00902 degrees for parts (a), (b), and (c), respectively.

The toxic salt will harm the salamander species.

Hence, the correct option is B,

To determine the concentration of the toxic salt in the ditch after it fully mixes and is diluted by the entire volume of the ditch, we can use the formula for concentration:

Concentration (C) = Mass of Salt (M) / Volume of Water (V)

Given:

Mass of Salt (M) = 60.2 mg

Volume of Water (V) = Area (A) * Length (L) = 0.5 \(m^{2}\) * 15 m = 7.5 \(m^{3}\)

Using the formula:

Concentration (C) = 60.2 mg / 7.5 \(m^{3}\)

Concentration (C) = 8.03 mg/ \(m^{3}\)

To convert from mg/ \(m^{3}\) to mg/L, we multiply by 1000:

Concentration (C) ≈ 8.03 mg/ \(m^{3}\) * 1000 = 8030 mg/L

The concentration of the toxic salt in the ditch, after it fully mixes and is diluted by the entire volume of the ditch, is approximately 8030 mg/L.

Since the concentration of the toxic salt exceeds the threshold for biological impairment, which is 100 mg/ \(m^{3}\) or 100 mg/L, the endangered salamander is at risk.

The concentration of the salt in the ditch is significantly higher than the level at which biological impairment occurs, indicating potential harm to the salamander species.

Therefore,The toxic salt will harm the salamander species.

Answer:

h = 0.047 m

Explanation:

It is given that,

Radius of an air bubble is 0.0003 m

The surface tension of water is \(7\times 10^{-2}\ N/m\)

We need to find the depth at which an air bubble of radius 0.0003 m will  remain in equilibrium in water. Let it is given by h.

Pressure due to surface tension is given by :

\(P=\dfrac{2T}{R}\) .....(1)

T is surface tension

Also, pressure due to a height is given by :

\(P=\rho gh\)

So, equation (1) becomes :

\(\rho g h=\dfrac{2T}{R}\)

So,

\(h=\dfrac{2T}{\rho gR}\)          

\(h=\dfrac{2\times 7\times 10^{-2}}{10^3\times 9.8\times 0.0003}\\\\h=0.047\ m\)

So, the depth is 0.047 m.

The formula for the energy stored in an inductor is E = (1/2) × L × I^2. Given that the inductor carries a current of 1.80 A and stores an energy of 0.250 mJ,

we can calculate its inductance as follows:

E = (1/2) × L × I^2

0.250 × 10^-3 J = (1/2) × L × (1.80 A)^2

L = (0.250 × 10^-3 J) / [(1/2) × (1.80 A)^2] = 26.0 μH

Therefore, the inductor's inductance is 26.0 μH.

(b) Using the same formula as in part (a), we can calculate the energy stored in the inductor when it carries a current of 3.3 A:

E = (1/2) × L × I^2

E = (1/2) × (26.0 μH) × (3.3 A)^2

E = 0.0587 mJ

Thus, the inductor stores 0.0587 mJ of energy when it carries a current of 3.3 A.

Hi there!

Counterclockwise.

If a loop of wire is placed in a magnetic field directed out of the page that disappears, that means that the magnetic flux out of the page through the loop has decreased.

The loop will try to oppose this change in the magnetic flux, so an induced current that produces an additional magnetic field out of the page will occur to make up for the decrease in the magnetic flux.

Using the magnetic right-hand rule, the current in the loop would need to be traveling in the counterclockwise direction in order for the produced magnetic field to be directed out of the page inside the loop.

The shortest stopping distance on dry pavement is approximately 87.6 meters, and to stop in the same distance on wet pavement, the speed should be approximately 20.2 m/s.

To determine the shortest stopping distance of an automobile, we can use the equations of motion and the concept of kinetic friction.

Given:

Coefficient of kinetic friction on dry pavement, μ_dry = 0.80

Coefficient of kinetic friction on wet pavement, μ_wet = 0.25

Initial velocity, v_initial = 29.1 m/s

a) Stopping distance on dry pavement:

To find the stopping distance on dry pavement, we need to determine the deceleration (negative acceleration) experienced by the car due to friction.

Using the equation of motion: v_final^2 = v_initial^2 + 2as, where v_final is the final velocity (zero in this case), a is the deceleration, and s is the stopping distance.

Rearranging the equation: s = v_initial^2 / (2a)

The deceleration can be calculated using the formula: a = μ * g, where μ is the coefficient of kinetic friction and g is the acceleration due to gravity (approximately 9.8 m/s^2).

Substituting the values, we have: a = 0.80 * 9.8 m/s^2

Now, we can calculate the stopping distance:

s_dry = v_initial^2 / (2 * a)

Substituting the given values, we get: s_dry = (29.1 m/s)^2 / (2 * 0.80 * 9.8 m/s^2)

Calculating this expression gives us a stopping distance on dry pavement of approximately 87.6 meters.

b) Stopping distance on wet pavement:

To determine the required speed on wet pavement, we want to find the velocity that will result in the same stopping distance as on dry pavement.

Using the same formula as before: s_wet = v_wet^2 / (2 * a_wet)

We can set the stopping distances on dry and wet pavement equal to each other: s_dry = s_wet

Substituting the values, we have: (29.1 m/s)^2 / (2 * 0.80 * 9.8 m/s^2) = v_wet^2 / (2 * 0.25 * 9.8 m/s^2)

Solving for v_wet, we find: v_wet ≈ 20.2 m/s

Therefore, to stop in the same distance on wet pavement as on dry pavement, the speed should be approximately 20.2 m/s.

The induced emf opposing the current is approximately -3.84 V for the 8.00 A current through a 4.00 mH inductor is switched off in 8.33 ms.

To find the induced emf in the inductor, we can use the formula:
emf = -L * (ΔI/Δt)
where:
emf = induced electromotive force (in volts)
L = inductance of the inductor (in Henrys)
ΔI = change in current (in amperes)
Δt = time taken for the current to change (in seconds)
Given the information in your question:
L = 4.00 mH = 4.00 * \(10^{-3}\) H (converting millihenry to henry)
ΔI = 8.00 A (since the current is switched off, the change is equal to the initial current)
Δt = 8.33 ms = 8.33 * \(10^{-3}\) s (converting milliseconds to seconds)
Now, we can plug these values into the formula:
emf = - (4.00 * \(10^{-3}\) H) * (8.00 A) / (8.33 * \(10^{-3}\) s)
emf = - (32 * 10^-3) / (8.33 * \(10^{-3}\))
emf ≈ -3.84 V
The induced emf opposing the current is approximately -3.84 V. The negative sign indicates that the induced emf opposes the change in current, as expected.

To find the EMF induced in the inductor, we'll need to use the formula for the induced EMF in an inductor, which is:

EMF = -L × (ΔI / Δt)

Here, EMF is the induced electromotive force, L is the inductance, ΔI is the change in current, and Δt is the time interval during which the current changes.

Given the information in your question, we have:

\(L = 4.00 mH = 0.004 H\) (converting millihenries to henries)
\(ΔI = 8.00 A\) (the current goes from 8 A to 0 A)
\(Δt = 8.33 ms = 0.00833 s\) (converting milliseconds to seconds)

Now, plug the values into the formula:

EMF =\(-0.004 H × (8.00 A / 0.00833 s)\)

F = force = 294 [N]

d = distance = 5 [m]

\(W = 294*5\\W = 1470 [J]\\\)

Efficiency is defined as the energy required to perform an activity in relation to the energy actually added to perform some activity. This can be better understood by means of the following equation.

a.  The force on the 113 cm side is 0N. b. The force on the 50.0 cm side is 0.120N. c. The 101 cm side force is 0.234N . d. The magnitude of the net force on the loop is 0.354 N

The magnitude of the magnetic force on each side of the loop can be determined using the formula F = I * L * B * sin(θ), where I is the current, L is the length of the side, B is the magnetic field magnitude, and θ is the angle between the magnetic field and the side of the loop. The net force on the loop can be obtained by summing the individual forces acting on each side.

(a) To calculate the magnitude of the magnetic force on the 113 cm side, we use the formula F = I * L * B * sin(θ). The current (I) is 3.66 A, the length (L) is 113 cm, the magnetic field magnitude (B) is 65.9 mT (converted to Tesla by dividing by 1000), and the angle (θ) is 0 degrees since the magnetic field is parallel to this side. Therefore, the force on the 113 cm side is F = 3.66 * 1.13 * 0.0659 * sin(0°) = 0 N.

(b) Similarly, for the 50.0 cm side, the force can be calculated using the same formula, but the length is 50.0 cm and the angle θ is 90 degrees since the magnetic field is perpendicular to this side. Thus, the force on the 50.0 cm side is F = 3.66 * 0.5 * 0.0659 * sin(90°) = 0.120 N.

(c) For the 101 cm side, the angle θ is also 90 degrees, so the force is F = 3.66 * 1.01 * 0.0659 * sin(90°) = 0.234 N.

(d) To find the net force on the loop, we sum the individual forces: 0 + 0.120 + 0.234 = 0.354 N.

Therefore, the magnitude of the net force on the loop is 0.354 N.
