The receiver of a signal must understand the code or language being used to avoid confusion and losses.
<h3>What is a Signal?</h3>
This is usually in the form of a sound or body movement and is involved in conveying messages to people.
The receiver must understand the code or language in order to prevent confusion or loss of lives and properties.

The electric field between the plates is equal to the potential difference across the plates divided by the separation of the plates.
The potential difference across the plates is equal to the charge stored divided by the capacitance.
Answer:
8.04 second
Explanation:
torque = 500 Nm
Length of blade, L = 2.4 m
mass of blade, m 40 kg
initial angular velocity, ωo = 0 rad/s
frequency, f = 2000 rpm = 2000 / 60 rps
final angular velocity, ωf = 2 x π x 2000 / 60 = 209.33 rad/s
Moment of inertia of the blade,
I = 19.2 kg m^2
Torque = Moment of inertia x angular acceleration
500 = 19.2 x α
where, α be the angular acceleration
α = 26.04 rad/s^2
Use first equation of motion
ω = ωo + αt
where t is the time taken by the propeller to reach 2000 rpm.
209.33 = 0 + 26.04 x t
t = 8.04 second
Thus, the time taken by the propeller is 8.04 second.
