Through Shannon's Theorem, we can calculate the capacity of the communications channel using the value of its bandwidth and signal-to-noise ratio. The capacity, C, can be expressed as
C = B × log₂(1 + S/N)
where B is the bandwidth of the channel and S/N is its signal-to-noise ratio.
Since the given SN ratio is in decibels, we must first express it as a ratio with no units as
SN (in decibels) = 10 × log (S/N)
30 = 10log(S/N)
log(S/N) = 3
S/N = 10³ = 1000
Now that we have S/N, we can solve for its capacity (in bits per second) as
C = 4000 × log₂(1 + 1000)
C = 39868.91 bps
Thus, the maximum capacity of the channel is 39868 bps or 40 kbps.
Answer: 40 kbps
I think it's 39.53
(please do calculate it. I am not completely sure)
Heat flow includes conduction, convection, and radiation. Conduction involves heat transfer through atoms bumping into each other.
Answer: 6.67 m/s
Explanation:
Recall that average speed is the total distance covered by a moving body divided by the total time taken. The SI unit is metres per second.
i.e Average speed = distance/time taken
Given that:
Distance covered = 6.00 km
Convert kilometers to meters
If 1 km = 1000 m
6.00 km = (6.00 x 1000) = 6000m
Time taken to school = 0.250 hours
Convert time in hours to seconds
If 1 hour = 60 minutes & 1 minute = 60 seconds
Then, 0.250 hours = (0.250 x 60 x 60)
= 900 seconds
Average speed = ?
Average speed = 6000m/900s
= 6.67 m/s
Thus, your average speed to school is 6.67 m/s
In pounds? Cuz if so 2.2 x 4.3 = 9.46
