Two events occur in an inertial system at the same time, but 4080 km apart. However in another inertial system these two events are observed to be 7550 km apart.
What is the time difference between the two events in this second inertial system?

The distance (perpendicular to the line from the center of the slit) where the intensity detected by the microphone is zero is approximately 11.83 meters.

The diffraction pattern produced by a slit of width 'a' is given by:

sinθ = λ / a

where λ is the wavelength of the wave and θ is the angle between the central maximum and the first minimum of the diffraction pattern.

In this case, the wavelength of the sound wave is 8.47 cm = 0.0847 m and the width of the slit is 9.65 cm = 0.0965 m. Therefore, the angle between the central maximum and the first minimum of the diffraction pattern is:

sinθ = λ / a

       = 0.0847 / 0.0965

       = 0.877

θ = sin⁻¹(0.877)

  = 60.7°

The distance between the slit and the microphone is 7.17 m. Let d be the distance from the center of the slit to the point where the intensity detected by the microphone is zero.

For the first minimum, the path difference between the wavelets from the top and bottom edges of the slit is half a wavelength (λ/2). This path difference results in destructive interference at the first minimum.

Using the diagram below, we can write:

sinθ = d / (d + x)

where x is the perpendicular distance from the central maximum to the point where the intensity is zero.

Substituting the value of θ and solving for x, we get:

x = d * tanθ

  = 7.17 * tan(60.7°)

  ≈ 11.83 m

Therefore, the distance (perpendicular to the line from the center of the slit) where the intensity detected by the microphone is zero is approximately 11.83 meters.

Answer:

Aim at the base of the fire and use short bursts until the fire is out.

Explanation:

Fire extinguishers use CO2 (Carbondioxide) as the extinguishing agent. This is because CO2 is denser than air, and does not support combustion.

Aiming at the base of the fire causes the CO2 to fall on the base of the fire, where the source of the fire is, trapping it, and preventing it from further reacting with air in a combustion reaction. Also, the short burst creates a strong wind that forces the flame to blow out.

The S.I. unit of E is NC^-1 and that of B is NA^-1 m^-1, then unit of E/B is A m/C (ampere meter per coulomb). This unit represents the ratio between the electric field and the magnetic field, indicating the strength and direction of the electromagnetic field.

The SI unit of electric field (E) is NC^(-1) (newton per coulomb) and the SI unit of magnetic field (B) is NA^(-1) m^(-1) (tesla). To determine the unit of E/B, we need to divide the unit of E by the unit of B.

Dividing the unit of E (NC^(-1)) by the unit of B (NA^(-1) m^(-1)), we can simplify the expression:

E/B = (NC^(-1))/(NA^(-1) m^(-1))

To simplify this expression, we can cancel out the common units in the numerator and denominator:

E/B = (N/C)/(N/(A m))

Now, let's simplify further by dividing the numerator and denominator:

E/B = (N/C) * (A m/N)

If the depth of the ocean at a particular place is 1817.5m, the time it would take a sonar signal to travel from a ship to the ocean bottom and back again would depend on the speed of sound in seawater.

The speed of sound in seawater at a temperature of 15°C (59°F) is around 1,530 meters per second. Therefore, to find the time it would take for the sonar signal to travel from the ship to the ocean bottom and back again, we can use the formula: Time = (2 x Depth) / Speed of Sound.

As we know that the depth of the ocean at a particular place is 1817.5 meters. Therefore, we can find out the time it would take for the sonar signal to travel from the ship to the ocean bottom and back again by substituting these values into the formula:

Time = (2 x Depth) / Speed of Sound Time = (2 x 1817.5) / 1530Time = 2.38 seconds.

Therefore, it would take approximately 2.38 seconds for a sonar signal to travel from a ship to the ocean bottom and back again at that particular location in the ocean. It's important to note that this is just an estimate and the actual time may vary depending on factors such as the temperature, pressure, and salinity of the seawater.

The time it would take for a sonar signal to travel from a ship to the ocean bottom and back again would depend on the depth of the ocean and the speed of sound in seawater. Using the formula Time = (2 x Depth) / Speed of Sound, we can estimate the time it would take for the sonar signal to travel based on these factors. In this case, the depth of the ocean was 1817.5 meters and the speed of sound in seawater was 1530 meters per second, so the estimated time it would take for the sonar signal to travel was 2.38 seconds.

If the pilot shuts down the engine at a height of 2.1 m and the velocity of the lander is 1.2 m/s, then the velocity of the lander at impact will depend on the acceleration due to gravity of the planet.

When the pilot shuts down the engine at a height of 2.1 m, the lander will continue to fall towards the planet's surface due to the planet's gravitational pull.

The velocity of the lander at impact will depend on the acceleration due to gravity of the planet. This is because the acceleration due to gravity determines how fast an object falls towards the planet's surface.

If we assume that the acceleration due to gravity of the planet is constant, then we can use the equations of motion to calculate the velocity of the lander at impact.

The equations of motion give us the relationship between the distance traveled, velocity, acceleration, and time. If we know any three of these variables, we can calculate the fourth.

Since the pilot shuts down the engine at a height of 2.1 m and the lander is already moving with a velocity of 1.2 m/s, we can use the equation:

Vf^2 = Vi^2 + 2ad

where Vf is the final velocity, Vi is the initial velocity, a is the acceleration due to gravity, and d is the distance traveled.

Using this equation, we can calculate the final velocity of the lander at impact. The answer will depend on the acceleration due to gravity of the planet.

(a)The pressure at B is 0.1248 atm.

(b)The temperature at C is 727.1 K.

(c)The total work done by the gas in one cycle is -1979J

General calculation:

We can use the First Law of Thermodynamics to analyze the heat engine cycle:

ΔU = Q - W

where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system. For a complete cycle, ΔU = 0, so:

Q = W

We can also use the ideal gas law to relate the pressure, volume, and temperature of the gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the absolute temperature.

(a)How to find the pressure at B segment?

To find the pressure at B, we can use the fact that the segment AB is an isothermal expansion. This means that the temperature remains constant, so:

PV = nRT

PB = (nRT)/(2V) = (2.00 mol)(0.0821 L·atm/mol·K)(600 K)/(2V) = (0.0821 L·atm/mol)(600 K)/V

Since the pressure at A is 5.00 atm, we can use the fact that the temperature is constant to find the volume at A:

PV = nRT

VA = (nRT)/P = (2.00 mol)(0.0821 L·atm/mol·K)(600 K)/5.00 atm = 197.76 L

Since the volume at B is twice the volume at A, we have:

VB = 2VA = 395.52 L

Substituting into the expression for PB, we get:

PB = (0.0821 L·atm/mol)(600 K)/395.52 L = 0.1248 atm

Therefore, the pressure at B is 0.1248 atm.

To find the temperature at C, we can use the fact that the segment BC is an adiabatic expansion. This means that no heat is added or removed from the system, so:

\(PV^\gamma\)= constant

where γ is the ratio of specific heats (for a monoatomic gas, γ = 5/3). We can use the fact that the volume at C is equal to the volume at A to find the pressure at C:

\(PAV^\gamma = PCV^\gamma\)

PC =  \(PA(V/A)^\gamma\) = 5.00 atm\((1/2)^(^5^/^3^)\) = 1.556 atm

Since the segment BC is adiabatic, the temperature changes but no heat is added or removed from the system. Using the ideal gas law, we can relate the pressure, volume, and temperature:

PV = nRT

TC = (PCVC)/(nR) = (1.556 atm)(197.76 L)/(2.00 mol)(0.0821 L·atm/mol·K) = 727.1 K

Therefore, the temperature at C is 727.1 K.

The total work done by the gas in one cycle is the sum of the work done in each segment of the cycle:

W = WAB + WBC + WCD + WDA

For segment AB, the work done is:

WAB = -QAB = -∫PdV = -nRT∫(1/V)dV = -nRT ln(VB/VA) = -(2.00 mol)(0.0821 L·atm/mol·K)(600 K) ln(2) = -602 J

For segment BC, the work done is:

WBC = -QBC = -∫PdV = -nγRT∫(1/V)dV = -nγRT

We know that VB = 2VA and VC = 2VD, so we can express the ratio VB/VC in terms of VA/VD:

VB/VC = (2VA)/(2VD) = VA/VD

Substituting into the expression for WBC, we get:

WBC = -nγRT ln(VA/VD)

For segment CD, the work done is:

WCD = -QCD + PCDΔV = -nCpΔT + PCDΔV

where Cp is the specific heat at constant pressure, ΔT is the change in temperature, and ΔV is the change in volume. We know that the segment CD is isobaric, so ΔV = VB - VA = (2VA) - VA = VA. We can also use the ideal gas law to relate the pressure, volume, and temperature:

Substituting into the expression for WCD, we get:

WCD = -nCpΔT + (nRT/VD)VA = -nCp(TC - TD) + (nRT/VD)VA

For segment DA, the work done is:

WDA = -QDA + ΔU = -nCvΔT

where Cv is the specific heat at constant volume. We know that the segment DA is isovolumetric, so ΔV = 0. Using the First Law of Thermodynamics, we know that ΔU = 0 for a complete cycle, so:

QDA = -WDA = nCvΔT

Substituting into the expression for WDA, we get:

WDA = -nCvΔT

Adding up the work done in each segment, we get:

W = WAB + WBC + WCD + WDA

= -(2.00 mol)(0.0821 L·atm/mol·K)(600 K) ln(2)- (2.00 mol)(5/3)(0.0821 L·atm/mol·K)(727.1 K) ln(VA/VD)- (2.00 mol)(Cp)(TC - TD) + (2.00 mol)(0.0821 L·atm/mol·K)(600 K) ln(2)- (2.00 mol)(Cv)(TC - TA)

We know that Cp and Cv for a monoatomic gas are related by Cp = Cv + R, so we can express Cp in terms of Cv:

Cp = Cv + R = (3/2)R + R = (5/2)R

Substituting and simplifying, we get:

W = (2.00 mol)(0.0821 L·atm/mol·K)(600 K) ln(2)- (2.00 mol)(5/3)(0.0821 L·atm/mol·K)(727.1 K) ln(VA/VD)- (2.00 mol)(5/2)(0.0821 L·atm/mol·K)(727.1 K)+ (2.00 mol)(5/2)(0.0821 L·atm/mol·K)(600 K)

W = -966.2 J - 4957 J - 7476 J + 5154 J

    = -1979 J

Therefore, the total work done by the gas in one cycle is -1979 J
