An airplane is flying 25° north of east at a speed of 820 km/h. How fast is it moving

Physics
1 answer:
Klio2033 [76]4 years ago
4 0

Answer:

A.350 km/h

Explanation:

Given,

The airplane is flying 25° north of east.

The speed of this plane is, v = 820 Km/h

The speed of the plane towards the north, Vn =?

The North direction is taken as the Y-axis and the East as X-axis

The direction of the plane forms an angle 25° with the X-axis,

Then the Y component is given by the sine angle

                                      <em>   Vn = v sin 25° </em>

                                               = 820 x 0.423

                                               = 347 Km/h

Hence, the plane is traveling with a speed towards north is, V = 350 Km/h

Yakvenalex [24]

Answer:

The correct answer is - true.

In the flow past a compression corner, the upstream Mach number and pressure are 3.5 and 1 atm, respectively. Downstream of the
yulyashka [42]

Answer:

\theta=23.7^{\circ}

Explanation:

The ratio of pressure 2 to 1 us 5.48/1= 5.48 rounded off as 5.5.

Referring to table A.2 of modern compressible flow then M_{\beta_1}=2.2

Also

M_{\beta_1}=M_1 sin \beta and making sin\beta the subject of the formula then

sin\beta=\frac {2.2}{3.5}\\\beta=38.94^{\circ}

Making reference to \theta-\beta-M diagram then

\theta=23.7^{\circ}

What is the mass, in grams, of 2.00 moles of H2O?
tia_tia [17]

Answer:

36g

Explanation:

Given parameters:

Number of moles of H₂O = 2moles

Unknown:

Mass of  H₂O = ?

Solution:

To solve this problem, use the expression below:

   Mass of  H₂O = number of moles x molar mass

Molar mass of  H₂O = 2(1) + 16  = 18g/mol

  Mass of  H₂O = 2 x 18  = 36g
