A block moves up a 30 degree incline under the action of three applied forces. F1 is horizontal and of magnitude 40 N. F2 is nor
Alja [10]

Answer

given,

F₁ is horizontal = 40 N

F₂ is normal = 20 N

F₃ is parallel = 30 N

work done by

W₂ = 0 as force is acting perpendicular to the direction of motion.

as the motion moved to 0.8 cm

W₃ = F₃ x d

W₃ = 30 x 0.8

W₃ = 24 J

W₁ = F₁ x d

W₁ = F₁ cos ∅ x d

W₁ = 40 cos 30⁰ x 0.8

W₁ = 27.21 J

Using carson's rule, what is the required bw to transmit an fm signal if the maximum deviation is 60 khz and intelligence freque
VashaNatasha [74]

Carson's Rule says:

FM occupied bandwidth =

(2) · (Peak deviation + Highest modulating frequency)

so

FM bw = (2) · (60 kHz + 15 kHz)

FM bw = (2) · (75 kHz)

FM bw = 150 kHz
