Magnitude of average acceleration  \(a_{avg}\)=2.75 units

Average acceleration \(a_{avg}=\) \(2.265 i- 1.58j\)

We're given that \(s=\frac{t^2}{4}\)

And partice is at A at t=2 s and at B at t= 2.2s

Instantaneous velocity \(\frac{ds}{dt} =\frac{t}{2}\)

Velocity at A  (\(V_{a}\)) at 2s = \(\frac{t}{2}\) or  \(\frac{t}{2}Cos \frac{\pi}{3} i+ \frac{t}{2}Sin \frac{\pi}{3}j=\frac{i+\sqrt{3} j}{2}\)

Velocity at B  (\(V_{b}\)) at 2.2s =\(\frac{t}{2}\) or \(\frac{t}{2}Cos \frac{\pi}{6} i+ \frac{t}{2}Sin \frac{\pi}{6}j=\frac{\sqrt{3}i+j }{2}\)

Average acceleration = \(\frac{V_{b}-V{a}}{t}\) =\(2.265 i- 1.58j\)

magnitude = \(\sqrt{(2.265)^2- (1.58)^2}\) = \(2.75\)

The density of air in the sealed container is approximately 1,060 hundred thousandth's lb/ft³.

To calculate the density of air in a sealed container, we need to convert the given pressure and temperature values to the appropriate units and then use the ideal gas law equation.

First, let's convert the pressure from psf (pounds per square foot) to pounds per square inch (psi) by dividing it by 144 (since there are 144 square inches in a square foot):

Pressure = 3409 psf / 144 = 23.6819 psi

Next, let's convert the temperature from Fahrenheit to Rankine by adding 459.67 (since Rankine is on the absolute temperature scale):

Temperature = 83°F + 459.67 = 542.67°R

Now, we can use the ideal gas law equation to calculate the density (ρ) of air:

Density (ρ) = Pressure / (Gas constant * Temperature)

The gas constant for air is approximately 1545 ft·lbf/(lb·R).

Density (ρ) = 23.6819 psi / (1545 ft·lbf/(lb·R) * 542.67°R)

Simplifying the equation and converting units:

Density (ρ) = (23.6819 * 144) lb/ft^2 / (1545 * 542.67) lb/(ft^2·°R)

Density (ρ) ≈ 0.0106 lb/ft^3

To express the density in hundred thousandth's, we multiply the density by 100,000:

Density (ρ) ≈ 1,060 hundred thousandth's lb/ft^3

Therefore, the density of air in the sealed container is approximately 1,060 hundred thousandth's lb/ft^3.

There are several types of CCTV cameras available in the market, but not all of them provide the option to adjust the distance that the camera can see. However, one type of CCTV camera that lets you adjust the distance is the varifocal camera.

A varifocal camera is a type of CCTV camera that comes with an adjustable lens, allowing the user to adjust the focal length manually. This feature provides the user with the flexibility to zoom in or out to get a closer or wider view of the area under surveillance.By adjusting the focal length, you can change the field of view of the camera, which affects the distance that the camera can see. For instance, if you need to monitor a small area like a doorway or a window, you can adjust the focal length to zoom in and get a more detailed view of the area. On the other hand, if you need to monitor a larger area like a parking lot, you can adjust the focal length to zoom out and get a wider view of the area.
In conclusion, if you need to adjust the distance that your CCTV camera can see, you should consider purchasing a varifocal camera as it provides you with the flexibility to zoom in or out and adjust the focal length manually.The type of CCTV camera that allows you to adjust the distance the camera can see is a varifocal camera.

Explain why the equivalent resistance of a parallel combination of resistors is always less than the smallest of the parallel resistors. Adding resistors in parallel gives the current a shorter path through which it can flow, hence decreasing the overall resistance.

The actual filtration rate (dV/dt) for a time interval of 45 minutes is given by the formula: dV/dt = Q/A = (300 L / 45 min) / A = 6.67 L/min.

Constant rate filtration is described by the equation P = av c A 2 (V) d V d t + R m A d V d t. If the average specific resistance and dry cake mass per unit volume of filtrate are constant, i.e. for incompressible filtration, then Eq. (5) should be linear. In Eq. 1, the "filtration constants"

300 L of filtrate were collected after 45 minutes.

The following calculation can be used to calculate the actual filtration rate (dV/dt):

\(dV/dt = A * (dh/dt)\)

(dV/dt) = Q/A

where Q represents the filtrate's volumetric flow rate.

As a result, the real filtration rate (dV/dt) at 45 minutes is:

dV/dt = Q/A = (300 L / 45 min) / A = (6.67 L/min) / A

The geometry of the problem can be modeled by a right triangle. The height of the cliff forms one leg, and the distance to a buoy forms the other leg. The angle of depression is opposite the height of the cliff. An appropriate trig relation is ...

  Tan = Opposite/Adjacent

Solving for the Adjacent side (the distance to the buoy), we find ...

  Adjacent = Opposite/Tan

  distance to buoy 1 = (80 m)/tan(23°) ≈ 188.468 m

  distance to buoy 2 = (80 m)/tan(15°) ≈ 298.564 m

Then the distance between the buoys is ...
