a swimmer experiences a total (absolute) pressure of 117,500 pa in a pool. how far below the surface are they located?

To design the second-order, low-pass filter, we can use a 15.92 nF capacitor and a 90 kΩ resistor. The op-amp circuit should be configured in a non-inverting amplifier configuration with the chosen resistor as the feedback resistor.

First, let's determine the transfer function of the filter. For a maximally flat response, we'll use a Butterworth filter. The transfer function of a second-order Butterworth low-pass filter is given by:

\(H(s) = ωₒ² / (s² + s√2ωₒ + ωₒ²)\)

where ωₒ is the angular frequency corresponding to the 3 dB cutoff frequency (1 kHz in this case). Substituting the values, we have:

\(H(s) = (2π * 1000)² / (s² + s√2 * 2π * 1000 + (2π * 1000)²)\)

Next, we need to determine the gain of the filter. Since we want a maximum gain of 10, we can choose a resistor value for the feedback path that sets the desired gain. Let's assume a feedback resistor of 10 kΩ.

Now, we can choose appropriate capacitor and resistor values for the filter. Let's start by selecting a capacitor value. To ensure an input impedance of 10 kΩ, we can use the formula:

Zin = 1 / (s * C)

Substituting the value of Zin (10 kΩ) and ωₒ (2π * 1000), we can solve for C. This gives us a value of approximately 15.92 nF.

With the capacitor value determined, we can calculate the resistor value using the gain equation:

Gain = 1 + (Rf / Ri)

Substituting the gain value (10) and the input resistor value (10 kΩ), we can solve for Rf. This gives us a value of 90 kΩ.

Answer:

The new pressure will be 12 atm

Two trains 130 m and 140 m long are running on parallel tracks in the same direction with a speed of 68 km/hr and 50 km/hr. How long will it take to clear off each other from the moment they meet?

Solution:            

Relative speed of trains = (68 – 50) km/hr

                               = 18 km/hr

                               = 18 × 5/18 m/sec

                               = 5 m/sec

Time taken by the train to clear off each other = sum of length of trains/relative speed of trains

                                                               = (130 + 140)/5 sec

                                                               = 270/5 sec

                                                               = 54 sec

2. The two trains are running on parallel tracks in the same direction at 70 km/hr and 50 km/hr respectively. The faster train passes a man 27 second faster than the slower train. Find the length of the faster train.

Relative speed of the trains = (70 – 50) km/hr

                                     = 20 km/hr

                                     = 20 × 5/18 m/sec

                                     = 50/9 m/sec

Length of the faster train = relative speed × time taken by train to pass

                                     = 50/9 × 27 m

When your rearview mirror is set to its night setting, it may hamper your ability to accurately judge the distance and speed of cars behind you.

This is because the mirror is designed to reduce glare from headlights and other bright lights, which can make it difficult to see objects that are farther away or moving quickly. Additionally, the reduced brightness of the mirror can make it harder to see details or colors, which can be important when identifying other vehicles on the road.
To compensate for these potential drawbacks, it's important to use other visual cues when driving at night. This might include relying on your side mirrors to monitor nearby traffic, paying close attention to street signs and road markings, and being extra cautious when changing lanes or merging onto highways. It's also a good idea to make sure your headlights are properly aligned and functioning, as this can help improve your visibility and reduce the need to rely solely on your rearview mirror.
Ultimately, driving at night requires extra attention and care, regardless of the settings on your rearview mirror. By remaining vigilant and staying aware of your surroundings, you can help ensure a safe and successful journey, even in low light conditions.

Therefore, when your rearview mirror is set to its night setting, it may hamper your ability to accurately judge the distance and speed of cars behind you.

The soil loss in  \(Mg ha^{-1}\) (Ton/ha) if the bulk density of the soil is 1.01  \(Mg m^{-3}\)  is option a. 0.202 Mg/ha.

For expressing the soil loss in \(Mg ha^{-1}\), need to convert the units appropriately. First, convert the soil loss from millimetres (mm) to meters (m) by dividing it by 1,000 (1 mm = 0.001 m). Thus, the soil loss is 0.0002 m.

Next, calculate the volume of soil lost per unit area (ha). The volume can be obtained by multiplying the soil loss (0.0002 m) by the area (ha). Since the bulk density of the soil is given as 1.01 \(Mg m^{-3}\), can convert the volume to mass by multiplying it by the bulk density.

Using the formula:

Soil loss (Mg ha-1) = Soil loss (m) × Bulk density (\(Mg m^{-3}\)) × Area (ha)

Substituting the values:

Soil loss (\(Mg ha-1\)) = 0.0002 m × 1.01 \(Mg m^{-3}\) × 1 ha

Calculating the result:

Soil loss (\(Mg ha-1\)) = 0.0002 × 1.01 = 0.000202 \(Mg ha-1\)

Therefore, the correct answer is option a. 0.202 Mg/ha.

As fluid is accelerated in an adiabatic nozzle, its kinetic energy rises. Internal energy is the source of the kinetic energy ( this conversion causes a temperature drop).

The flow in the nozzle increases in speed and the gas expands significantly (the pressure, temperature, and density all fall dramatically). You're curious about the source of the gas' significant focused kinetic energy.

The thermal energy that was present in the hot gas upstream of the nozzle in the combustion chamber is where this kinetic energy originates. A gas with a high temperature has molecules traveling about it at fast speeds and in an erratic manner. The nozzle's dimensions are such that when those swiftly moving molecules bounce off its walls, they are sent downstream (out the nozzle exit). This converts random movements into directed ones.

A skydiver who has stepped from a helicopter and is falling through air, before she reaches terminal speed and long before she opens her parachute her speed increases, until she reaches terminal speed.

The highest speed that an item may reach as it descends is referred to as terminal velocity. Because the effects of air resistance on various objects vary depending on their shapes, the terminal velocity speed will be different for each item.

An object will attain its maximum speed when it falls from a low height (like a table) but this is not the terminal velocity since if the object had been allowed to fall for longer, it would have continued to gain speed. If an object was dropped from a height twice as great, the terminal velocity would remain the same.

Explanation:

The total resistance of the circuit is

\(r = \frac{(40)(30)}{40 + 30} + \frac{(50)(20 + 10)}{50 + (20 + 10)} \\ = 35.89 \: ohms\)

so the total current is

Itotal= V/R = 9V/35.89 ohms

= 0.25 A

To find the voltage drop across the 30-ohns resistor, use

V = Itotal × (combined resistance of 40 30)

= 0.25 A × 17.14 ohms = 4.285 volts

so the current through the 30-ohm resistor is

I = (voltage drop)/30-ohms

= (4.285 V)/(30 ohms)

= 0.143 A

For a parallel circuit the voltage across each resistor is the same. Therefore, the voltage drop across the 30 Ω resistor is 9V. Then, the current through this resistor is 0.3 A.

Resistance is the hindrance to the flow of current through a circuit. It is expressed in Ohms. Resistance and current are in inverse proportion. According to Ohm's law, the product of current and resistance is the voltage across the circuit.

V = I R

There are two type of circuits parallel and series. Parallel circuits connects each components in parallel fashion where, the current through each one will be different and voltage is constant.

In a series circuit, the voltage drop across each component is different but the current is the same.

Here, the resistors are connected in a parallel fashion. Hence the voltage drop across each resistors will be 9 V itself.

then current across 30 Ω resistor is:

I = V/R

 = 9 v/ 30 Ω

 = 0.3 A.

Therefore, the current through the resistor of 30 Ω  is 0.3 A.

(a) magnitude of the final velocity is 11.94 m/s, and the (b) angle of the final velocity with respect to the positive x-axis is 37.1°.

We can tackle this issue utilizing kinematic conditions. Since the speed increase is consistent, we can utilize the accompanying conditions:

v = u + at

s = ut + 1/2 \(at^2\)

\(v^2 = u^2\) + 2as

where u is the underlying speed, v is the last speed, t is the time, s is the dislodging, and an is the speed increase.

Given: u = 4.00 m/s I, a = 5.00\(m/s^2\) I + 7.00 \(m/s^2\) j, s = 12.0 m lined up with the x-pivot.

Utilizing the second kinematic condition, we can address for the time taken to venture to every part of the distance:

s = ut + 1/2 \(at^2\)

12.0 = 4.00t + 1/2 (5.00)\(t^2\)

5.00\(t^2\) + 4.00t - 12.0 = 0

Settling for t utilizing the quadratic recipe, we get:

t = 1.09 s (taking the positive root)

Utilizing the first kinematic condition, we can tackle for the last speed in the x-course:

v_x = u_x + a_x t

v_x = 4.00 + 5.00(1.09)

v_x = 9.45 m/s

Utilizing the Pythagorean hypothesis, we can track down the greatness of the last speed:

|v| = sqrt(\(v_x^2 + v_y^2\))

|v| = sqrt((\(9.45)^2\) + (\(7.00)^2\))

|v| = 11.94 m/s

Utilizing the reverse digression capability, we can track down the point of the last speed regarding the positive x-hub:

θ = \(tan^(- 1)\)(v_y/v_x)

θ = \(tan^(- 1)\)(7.00/9.45)

θ = 37.1°

True. Warm air expands faster, leading to a more rapid decrease in air pressure with height than in cold air.

True. In a warm air column, the air molecules have higher kinetic energy and move more vigorously. This increased motion leads to greater expansion of the air column and a more rapid decrease in air pressure with height. As the warm air rises, it expands and becomes less dense, causing the pressure to decrease at a faster rate. In contrast, in a cold air column, the air molecules have lower kinetic energy and move more slowly.

The reduced motion results in less expansion of the air column and a slower decrease in air pressure with height. Therefore, air pressure decreases more rapidly with height in a warm air column compared to a cold air column.

The correct answer is B) real, inverted, and magnification less than one.

When an object is placed closer to a concave mirror than its focal point distance, the image formed is real, inverted, and magnified. This is a result of the reflective properties of a concave mirror and the rules of ray optics. A real image is formed when the reflected light rays actually converge at a point. In this case, the real image is formed in front of the concave mirror. The image formed is also inverted, meaning it is upside down relative to the object. This occurs because the rays of light coming from the object converge after reflection at the mirror's surface. Furthermore, the magnification of the image is less than one. This means that the image appears smaller than the object. The magnification can be calculated as the ratio of the image height to the object height.

In summary, when the object's distance from a concave mirror is less than the focal point distance, the resulting image is real, inverted, and has a magnification less than one.
