Explanation:
( a )
<u>The four types of spread spectrum techniques are as follows -</u>
1. Direct sequence spread spectrum .
2. frequency hopping spread spectrum .
3. chirp spread spectrum .
4. time hopping spread spectrum .
( b )
<u>The Direct sequence spread spectrum was devised for eavesdropping in the military .</u>
In the field of telecommunications , the Direct sequence spread spectrum , it is the technique of spread spectrum modulation which is used to reduce the overall inference of the signal .
Answer:
the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
Explanation:
a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below
As we know that
Pressure = F ÷ area
Also
F = mg
Now
= (1500 × 9.8) ÷π (0.24)^2
= 81,726 N/m^2
Hence, the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
