Answer:
We can easily find out the beginning point of the line by using dot representation. When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system. The vector is a straight line that has a certain end which is fixed to its body
Answer:
im 99% sure its initial disturbance
Explanation:
Answer: 9.08KW and 16.21KW
Explanation:
The convection over a flat surface with a length of 10 m and a width of 6m.
The mean temperature is (5oC + 12oC)/2 = 8.5oC.
Then find the following properties of air at this temperature from Table A-15:
k = 0.02428 W/m(oC, v= 1.413x10-5 m2/s, and Pr = 0.7340.
find the Reynolds number. Re= VL/v
Check screenshot
This means that the flow becomes turbulent over the plate and we can use the Nusselt number equation for combined laminar and turbulent flow.
Check screenshot
We then use this Nusselt number to find the heat transfer coefficient and the heat transfer.

Ans
9.08 kW
Then if the wind velocity were doubled, the Re number would be doubled and we would repeat the calculations above, starting with this revised Reynolds number..
Ans
16.21 kW
Answer: Remains constant
Explanation:
The acceleration of the body under the free fall always remains constant. A body falling freely after reaching its maximum height when launched is under the influence of gravitational force (g) and the value is positive for downward fall.
Note that the acceleration possessed by the body is acceleration due to gravity which is the same at any point during the fall i.e 9.81m/s².
