Answer:
carrier power is 16.1 kW
Explanation:
given data
power transmit P = 20 kW
modulation index m = 0.7
to find out
carrier power
solution
we will apply here power transmit equation that is express as
...............1
put here all value in equation 1 we get carrier power
solve it we get
carrier power = 16.1
so carrier power is 16.1 kW
(3) The amount of energy a sound wave transmits is directly related to the wave's amplitude.
We can even tell this physically because the larger the amplitude, the louder sound is.
Answer:
A = 150 cm at 120 degc
Where A + B = C find B
B = C - A add -A to both sides
Ax = 150 cos 60 = -75
Ay = 150 sin 60 = 129.9
Likewise
Cx = 114.7
Cy = 80.3
Bx = Cx - Ax = 114.7 + 75 = 189.7
By = Cy - Ay = 80.3 -129.9 = -49.6
B = (189.7^2 + 49.6^2)^1/2 = 196.7 length of B vector
tan B = By / Bx = -49.6 / 189.7 B = -14.65 deg
Also
sin B = By / B = -49.6 / 196.1 = -14.65 deg
So B is 196.1 cm at -14.65 deg
Pressure = F/A
Where,
F = Force exerted = 150 N
A = Area = 1*0.5 = 0.5 m^2
Therefore,
Pressure exerted by wind on the wind = 150/0.5 = 300 N/m^2
1 N/m^2 = 1 Pa,
Then,
Pressure, P = 300 Pa
