A ship has a speed in still water of 10 ms¹ and is pointed in the direction N 30°E, but there is a current of speed 2 ms-¹ flowing towards the direction SE. By applying the Cosine or Sine Rule, find the resultant velocity of the ship, in terms of its speed and a bearing. Give your answers correct to one decimal place.
Answers
Answer:
Hope this helped ^^
Explanation:
To find the resultant velocity of the ship, we can use vector addition by considering the ship's velocity in still water and the velocity of the current separately.
Let's denote the ship's velocity in still water as Vship = 10 m/s, and the velocity of the current as Vcurrent = 2 m/s.
To find the resultant velocity, we can break down the ship's velocity and the current's velocity into their horizontal (East/West) and vertical (North/South) components.
The horizontal component of the ship's velocity (Vship_h) can be calculated using the cosine rule:
Vship_h = Vship * cos(30°)
Vship_h = 10 * cos(30°) = 10 * (√3 / 2) ≈ 8.7 m/s
The vertical component of the ship's velocity (Vship_v) can be calculated using the sine rule:
Vship_v = Vship * sin(30°)
Vship_v = 10 * sin(30°) = 10 * (1 / 2) = 5 m/s
Now, since the current is flowing towards the direction SE (southeast), which is 45° from the East direction, we can break down the current's velocity into its horizontal and vertical components.
The horizontal component of the current's velocity (Vcurrent_h) can be calculated using the cosine rule:
Vcurrent_h = Vcurrent * cos(45°)
Vcurrent_h = 2 * cos(45°) = 2 * (√2 / 2) = √2 m/s
The vertical component of the current's velocity (Vcurrent_v) can be calculated using the sine rule:
Vcurrent_v = Vcurrent * sin(45°)
Vcurrent_v = 2 * sin(45°) = 2 * (√2 / 2) = √2 m/s
Now, we can find the resultant horizontal velocity (Vresultant_h) by adding the horizontal components of the ship's velocity and the current's velocity:
Vresultant_h = Vship_h + Vcurrent_h
Vresultant_h = 8.7 + √2 ≈ 10.1 m/s
Similarly, we can find the resultant vertical velocity (Vresultant_v) by adding the vertical components of the ship's velocity and the current's velocity:
Vresultant_v = Vship_v + Vcurrent_v
Vresultant_v = 5 + √2 ≈ 6.4 m/s
Finally, we can calculate the magnitude of the resultant velocity (Vresultant) using the Pythagorean theorem:
Vresultant = √(Vresultant_h² + Vresultant_v²)
Vresultant = √(10.1² + 6.4²) ≈ 11.9 m/s
The bearing of the resultant velocity can be calculated using the inverse tangent (tan⁻¹) of the vertical component divided by the horizontal component:
Bearing = tan⁻¹(Vresultant_v / Vresultant_h)
Bearing = tan⁻¹(6.4 / 10.1) ≈ 33.7°
Therefore, the resultant velocity of the ship, in terms of its speed and bearing, is approximately 11.9 m/s at a bearing of 33.7°.

What is the perimeter of rectangle � � � � ABCDA, B, C, D?
Answers
As per the data given in the question, the perimeter of rectangle ABCDA is 14 units.
To find the perimeter of the rectangle ABCDA, we need to calculate the sum of the lengths of all four sides.
The coordinates of the vertices are as follows:
A(2, -6)
B(5, -6)
C(5, -2)
D(2, -2)
Let's calculate the length of each side:
Side AB: Distance between points A and B
AB = sqrt\(((5 - 2)^2 + (-6 - (-6))^2)\)
= \(sqrt(3^2 + 0^2)\)
= sqrt(9)
= 3
Side BC: Distance between points B and C
BC = sqrt\(((5 - 5)^2 + (-2 - (-6))^2)\)
= sqrt\((0^2 + 4^2)\)
= sqrt(16)
= 4
Side CD: Distance between points C and D
CD = sqrt\(((2 - 5)^2 + (-2 - (-2))^2)\)
= sqrt\(((-3)^2 + 0^2)\)
= sqrt(9)
= 3
Side DA: Distance between points D and A
DA = sqrt\(((2 - 2)^2 + (-2 - (-6))^2)\)
= sqrt\((0^2 + 4^2)\)
= sqrt(16)
= 4
Now, let's calculate the perimeter by adding the lengths of all four sides:
Perimeter = AB + BC + CD + DA
= 3 + 4 + 3 + 4
= 14
Therefore, the perimeter of rectangle ABCDA is 14 units.

A tornado may be simulated as a two-part circulating flow in cylindrical coordinates, with Vr = Vz = 0. Vtheta = ωr if r ≤ R and Vtheta = ωR2 / r if r ≥ R. Determine the vorticity and the strain rates in each part of the flow.
Answers
Explanation:
\($V_{\theta} = \omega r , r \leq R $\)
= \($\omega \frac{R^2}{r} $\) , r> R
\($V_r = V_z = 0$\)
Inner region vorticity
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(rv_{\theta})\)
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(r\omega r), (e\omega \neq 0)\) (rotational)
Outer region vorticity
\(\Omega _z =\frac{1}{r}.\frac{d}{dt}(\omega e^2/r)\)
= 0 (irrotational)
Strain rate of the inner region
\(e_{\theta \theta}=\frac{1}{r}.\frac{\delta u_{\theta}}{\delta \theta}+\frac{u_r}{r}=0\)
\(e_{z z}=\frac{\delta u_z}{\delta z}=0\)
\(e_{r r}=\frac{\delta u_r}{\delta r}=0\)
\(e_{r \theta}=e_{\theta r}=\frac{1}{2}\left \{ r.\frac{\delta}{\delta r} \left ( \frac{u_{\theta}}{r} \right )+\frac{1}{r}.\frac{\delta u_r}{\delta \theta}\right \}\)
\(e_{r \theta}=e_{\theta r}=\frac{1}{2}\left \{ r.\frac{\delta}{\delta r} \left ( \frac{\omega r}{r}+\frac{1}{r}(0) \right )\right \}\)
= 0
Therefore, the strain rate are 0.
\(e_{r \theta }= e_{\theta r} =\frac{1}{2}\left \{ r \frac{\delta}{\delta r} \left ( \frac{\delta u_{\theta}}{\delta r} \right )+\frac{1}{r}\frac{\delta v_r}{\delta \theta} \right \}\)
\(= \frac{1}{2}\left \{ r. \frac{\delta}{\delta r}\left ( \frac{\omega R^2}{r^2} \right )+\frac{1}{r}. \frac{\delta v_r}{\delta \theta} \right \}\)
\(= \frac{1}{2}\left \{ v-\frac{2}{v^3} .\omega R^2 \right \}\)
\(= -\frac{\omega R^2}{r^2}\)

4. Tony Hawk weighs about 60 kg. Calculate the difference in the pressure placed on the snow if he was standing in the snow on one snowshoe compared to standing in the snow in one boot. The area of the snowshoe is 0.20 m² and the area of the boot is 0.05 m².
Answers
The difference in pressure placed on the snow when Tony Hawk stands on one snowshoe compared to standing in one boot is 800 Pa.
1. Convert the weight of Tony Hawk from kg to N (Newton):
Weight = Mass x Gravity
Given that Tony Hawk weighs about 60 kg and the acceleration due to gravity is approximately 9.8 m/s²,
Weight = 60 kg x 9.8 m/s² = 588 N
2. Calculate the pressure exerted by Tony Hawk on the snow when standing on one snowshoe:
Pressure = Force / Area
Given that the area of the snowshoe is 0.20 m²,
Pressure on snowshoe = 588 N / 0.20 m² = 2940 Pa
3. Calculate the pressure exerted by Tony Hawk on the snow when standing in one boot:
Given that the area of the boot is 0.05 m²,
Pressure on boot = 588 N / 0.05 m² = 11760 Pa
4. Calculate the difference in pressure placed on the snow:
Difference in pressure = Pressure on snowshoe - Pressure on boot
Difference in pressure = 2940 Pa - 11760 Pa = -8820 Pa
Note: The negative sign indicates that the pressure on the snowshoe is lower compared to the pressure on the boot. However, in this context, the absolute value of the difference (8820 Pa) represents the magnitude of the pressure difference.

Answers
Since tech a says to lift the engine by looping straps around the rocker arm shafts and tech b says to lift the engine by using a strap under the oil pan. Neither of them is correct.
How should an engine be lifted correctly?Through direct contact between these components and the tappets and in accordance with the movement of the shaft, the rocker arm is the component in charge of transferring the movement of the camshaft towards the engine's intake and exhaust valves.
Therefore, in lifting, your chains should be in the middle of the hoist hook and the engine. To make certain that everything is disconnected, start carefully jacking up the engine. As soon as the engine is free of the car, continue jacking. Lower the engine onto blocks for security and support after moving the hoist to the desired location.
