Answer:

a) 3.18 degree.

Explanation:

tan Ф =  v sinα /( u + v cos α )

v is velocity of the air , u is velocity of pilot , α is angle between u and v and Ф is drift angle of the pilot

tan Ф = 18 sin ( 290 - 224) / 300 + 18 cos ( 290 - 224 )

           = 18 sin 66 / ( 300 + 18 cos 66)

             = 18 x .91 / (300 + 18 x .40)

               = 16.38 / 305.4 = .0536

       Ф = 3 .18 degree.

On the decibel scale, an increase of 10 decibels means an intensity increase of __________times?
Sonbull [250]

Answer:

10

Explanation:

The decibel or decibel, is a unit that relates two values ​​of sound pressure, and electrical power. the base unit is the bel, but given the amplitude but for practicality, a submultiple, the decibel, is used. It is a scalar expression .

Zero belios is the reference value used as a base, hence a bel is equivalent to 10 decibels and means that there is a power increase of 10 times over the reference value.
