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 ratio of the induced EMF in the loop CDBC to the induced EMF in the loop CADC can be calculated as follows:

ecdbc/ecadc = -dΦ_cdbc/dt / (-dΦ_cadc/dt) = dΦ_cadc/dt / dΦ_cdbc/dt

Let's dive deeper into the details below

The induced EMF is the voltage generated by a changing magnetic field in a coil of wire. In a loop, the induced EMF is proportional to the rate of change of the magnetic flux that is threading the loop. Therefore, in a loop, the induced EMF can be calculated as:

induced EMF = -dΦ/dt, where Φ is the magnetic flux threading the loop.

We can assume that both loops are parallel to the surface and therefore perpendicular to the magnetic field. This means that the magnetic flux threading each loop is proportional to the area of the loop, as follows:

Φ_cadc = B A_cadc and Φ_cdbc = B A_cdbc

Therefore, the ratio of the induced EMF in the loop CDBC to the induced EMF in the loop CADC can be calculated as follows:

ecdbc/ecadc = dΦ_cadc/dt / dΦ_cdbc/dt = (B A_cadc)/dt / (B A_cdbc)/dt = A_cadc / A_cdbc

The answer is the ratio of the areas of the loops.

Answer:

One of the most common injuries that result from working on a scaffold is electrocution. If workers make contact with those wires while working, it can lead to electric shock, especially if that contact damages the wire or if the scaffold is made of metal.

One of the hazards in scaffolding is inadequate assembly

Scaffolding is a temporary structure often used in construction, maintenance, and other projects to provide a platform for workers to access higher areas. However, if not properly assembled, it can become a hazard.

If scaffolding is not assembled correctly, it may lack stability and structural integrity.

This can lead to the scaffolding collapsing, causing workers to fall from significant heights. Improper assembly might involve using incorrect components, insufficiently securing connections, or neglecting safety guidelines

From the question above we can take hold of the statement Below because it is going to assist or help us in solving this particular Question or problem;

" Measurements indicate that the material of tank B will fail and the tank will burst if the air pressure in tank B exceeds 18 kPa."

=> Also, the density of oil = 930

That is if Pressure, P in B > 18kpa there will surely be a burst.

The height, h the can waste oil be poured into tank A is;

The maximum pressure  = height × acceleration due to gravity × density) + ( acceleration due to gravity × density × height, j).

18 × 10^3 = (height, h ×  10 × 930) + 10 × (2 - 1.25) × 1000.

When we make height, h the Subject of the formula then;

Approximately, Height, h = 1.2 metres.

(2). If air is accidentally trapped in the manometer line, what will be the error in the calculation of the height we will have the same pressure.

When the DME (Distance Measuring Equipment) malfunctions at or above 24,000 feet MSL, the correct procedure is to immediately notify ATC (Air Traffic Control) and request an altitude below 24,000 feet. So the correct answer is A. Notify ATC immediately and request an altitude below 24,000 feet.

This is because DME is required above this altitude for navigation and separation purposes.

To determine the convection heat flux in each scenario, we can use the formula Q = hA(T_surface - T_surrounding), where Q is the heat flux, h is the convection coefficient, A is the surface area, and T_surface and T_surrounding are the temperatures of the surface and the surrounding medium, respectively.

For scenario (a):
- Vehicle speed: 40 km/h
- Air temperature: -8°C
- Surface temperature: 30°C
- Convection coefficient: 40 W/m²·K

First, we need to convert the vehicle speed from km/h to m/s:
40 km/h = (40 * 1000) m / (60 * 60) s ≈ 11.11 m/s

Next, we can calculate the heat flux:
Q = 40 W/m²·K * A * (30°C - (-8°C))

Now, let's move on to scenario (b):
- Water stream velocity: 0.2 m/s
- Water temperature: 10°C
- Surface temperature: 30°C
- Convection coefficient: 900 W/m²·K

For this scenario, we can calculate the heat flux using the same formula:
Q = 900 W/m²·K * A * (30°C - 10°C)

To determine which condition feels colder, we compare the heat flux values. The higher the heat flux, the faster heat is transferred away from the hand, making it feel colder.

Now, let's compare the heat flux values with the approximate heat flux under normal room conditions (30 W/m²):
- If the heat flux is higher than 30 W/m², the condition would feel colder.
- If the heat flux is lower than 30 W/m², the condition would feel warmer.

To find the convection heat flux, we use the formula Q = hA(T_surface - T_surrounding). By calculating the heat flux for each scenario, we can determine which condition would feel colder by comparing the values with the approximate heat flux under normal room conditions.

There are various variations on the cycle in light of the weight territory at which it is directed, the kind of reactants, and whether some strategy to actuate the response is utilized. CVD can likewise be directed in a nuclear layer testimony (ALD) mode in which single layers of molecules are created each in turn. CVD has a number of points of interest over actual fume testimony. For instance, the response can frequently be organized to be particular all the more effectively, saving material just in specific districts of the substrate as opposed to covering it

Explanation:

A single pipe with diameter of about 171.5 mm would give the same discharge as the two parallel pipes.

The discharge in each pipe is calculated as follows:For the first pipe with diameter d1 = 50, the cross-sectional area A1 is given as:

A1 = π (d1/2)2 = π (50/2)2 = 1963.5 mm2

For the second pipe with diameter d2 = 100, the cross-sectional area A2 is given as:

A2 = π (d2/2)2 = π (100/2)2 = 7854.0 mm2

The hydraulic head h is the difference in level between the two reservoirs which is given as 10 m.

The friction factor f is given as 0.008.

The length of each pipe is 100 m.

Now we can apply the Darcy-Weisbach equation for head loss hL:

For the first pipe:  hL1 = f (L/d1) (V1^2/2g) where V1 is the velocity in the first pipe.

For the second pipe:  hL2 = f (L/d2) (V2^2/2g) where V2 is the velocity in the second pipe.

The flow rate in each pipe Q is given by Q = VA where V is the velocity and A is the cross-sectional area.

Substituting V = Q/A into the Darcy-Weisbach equation and solving for Q, we obtain:

For the first pipe: Q1 = A1 √(2gh/(fL/d1+K)) where K is the minor losses coefficient which we assume to be negligible for now.

For the second pipe: Q2 = A2 √(2gh/(fL/d2+K))

The discharge in each pipe Q is given by the following:

Q1 = A1 √(2gh/(fL/d1+K)) = 1963.5 mm2 √(2 × 9.81 m/s2 × 10 m / (0.008 × 100 m / 50 + 0)) = 0.029 m3/sQ2 = A2 √(2gh/(fL/d2+K)) = 7854.0 mm2 √(2 × 9.81 m/s2 × 10 m / (0.008 × 100 m / 100 + 0)) = 0.116 m3/s

To find the diameter of a single pipe that would give the same discharge as the two parallel pipes, we can use the following equation:

Q = VA = π (d/2)2 Vd = (4Q / π) / Vwhere V is the velocity of flow in the single pipe. Setting the two flow rates Q1 and Q2 equal to the flow rate Q in the single pipe, we obtain:

Q1 = Q2 = Q = (4Q / π) / Vd1 = d2/2 therefore d2 = 2d1

Substituting d2 = 2d1 and Q = (4Q / π) / V into the equation above, we obtain:Q = π (d1/2)2 V = π (d2/4)2 VQ = 0.029 m3/sV = Q / (π (d1/2)2) = 0.029 m3/s / (π (50/2)2) = 0.023 m/sd = 2 × √(Q / (πV)) = 2 × √(0.116 m3/s / (π × 0.023 m/s)) ≈ 171.5 mm

Therefore, a single pipe with diameter of about 171.5 mm would give the same discharge as the two parallel pipes.
